The structural chemistry of the polymeric 1:1 adducts of copper(1) halides ( CuX ; X = Cl, Br, I) with nitrile bases (exemplified by aceto- and benzo-nitrile ) has been systematically explored. Single-crystal X-ray structure redeterminations of enhanced precision have been carried out for all acetonitrile adducts (refined as orthorhombic, Pbnm , Z 4, a ≈ 13.0, b ≈ 8.5, c ≈ 4.0 � ; R 0.039, 0.030, 0.043 for No = 534, 365, 727 'observed' reflections) and the chloride and bromide benzonitrile adducts (monoclinic, P21/n, a ≈ 3.9, b ≈ 17.5, c ≈10.9 � , β ≈ 98, Z 4); R 0.046, 0.048 for No = 1452, 1209); all structures are of the common one-dimensional 'stair' polymer type. In these adducts, the ligand is essentially 'one-dimensional' with substituents well removed from the point of attachment and from interaction within the parent polymer chain. Under these circumstances, the polymer is essentially 'orthogonal' with Cu-X crosslinks at (or nearly at) right angles to the polymer axis, and containing quasi-mirror planes, the series providing reference parameters for the description of distortions observed in these polymers when more hindered bases are coordinated.

The synthesis and room-temperature single-crystal X-ray structure determination of the 1 : 1 adduct of silver(I) nitrate with triphenylstibine, AgNO3/SbPh3 (1 : 1), is recorded, being monoclinic, Cc,a 12·824(2), b 15·794(4),c 9·796(2) Å, β 117·50(1)°, Z= 4; conventional R on F was 0·030 for 2881 independent ‘observed’ (I > 3σ(I)) reflections. The complex is a one-dimensional polymer with bridging nitrate groups, resembling in this respect its phosphine and arsine analogues. The completion of this study, along with related species recorded in accompanying papers, means that full structural data are now available for the complete array AgNO3/EPh3 (1 : n), E = P, As, Sb, n = 1–4, with the one exception of E = Sb, n = 2.

Adducts of lead(II) nitrate with 2,4,6-tris(2-pyridyl)-1,3,5-triazine (' trz ') have been synthesized and structurally characterized by room-temperature single-crystal X-ray studies, for 1:1 and 1:2 stoichiometry. Crystals of [( trz ) Pb (NO3)2](∞|∞) are monoclinic, P 21/c, a 10.531 (1), b 12.856(2), c 16.874(3) Ǻ, β 102.83(1)°, Z = 4 f.u .; R was 0.027 for No = 2773 'observed' (I > 3σ(I)) reflections. The complex is an infinite polymer; the plane of the tridentate trz ligand lies normal to the polymer axis ( Pb -N(central; distal) 2.523(5); 2.594(5), 2.568(5) Ǻ) with unsymmetrically bidentate nitrate groups to either side ( Pb -O 2.598(6), 2.928(7); 2.556(6), 2.911(7) Ǻ). The third oxygen of each nitrate group bridges to the next lead atom in the polymer chain ( Pb -O 3.008(5), 3.083(6)Ǻ). [( trz )2Pb(NO3)2] is monoclinic, C 2/c, a 15.723(5), b 10.034(2), c 24.379(15) Ǻ, β 106.84(4)°, Z = 4 f.u .; R was 0.038 for No 3030. The compound is a methanol monosolvate. The complex species is mononuclear, with the lead atom located on a crystallographic 2 axis and 10-coordinated by pairs of symmetry-related tridentate trz ( Pb -N(central; distal) 2.779(4); 2.800(5), 2.818(5) Ǻ) and bidentate nitrate ligands ( Pb -O 2.796(6), 2.689(5)Ǻ). A hexahydrate has also been obtained (triclinic, Pī a 23.580(9), b 10.147(4), c 9.762(4)Ǻ, α 113.14(3), β 92.11(3), γ 101.60(3)°, Z = 2 f.u ; R 0.041 for No 5633); although metal-ligand distances are similar to those found in the methanol solvate, and quasi-2 symmetry is retained, a very different stereochemistry is evident in respect of the relative dispositions of the ligands about the (quasi)-2 axis, involving a substantial twist of the two nitrate ligands relative to the triazines, and a flattening of the latter. The coordination polyhedron is different in the two 1:2 adducts. In the methanol solvate the stereochemistry is pentagonal antiprismatic whereas in the hexahydrate it is bicapped square antiprismatic.

Adducts (1 : 1) of copper(I) chloride, bromide and thiocyanate with quinoline have been synthesized and have been the subject of single-crystal X-ray structure determinations at 295 K. Crystals of the chloride are orthorhombic, P 212121, a 15.358(7), b 14.309(6), c 3.801(2)Ǻ, Z 4; R was 0.055 for 541 'observed' reflections. Crystals of the bromide are monoclinic, C2/c, a 19.417(5), b 14.048(4), c 15.753(6) Ǻ, β 125.31(2)°, Z 4 tetramers; R was 0.049 for 1138 'observed' reflections. Crystals of the thiocyanate are monoclinic, P 21/c, a 5.682(1), b 10.412(2), c 16.838(5)Ǻ, β 97.48(2)°, Z 4 f.u .; R was 0.045 for 914 'observed' reflections. The chloride takes the form of the common 'stair' polymer, unexpectedly, while the thiocyanate is an expanded version of the same. The bromide provides a second example of a novel tetrameric 'basket' structure exemplified previously by the iodide analogue.

Recrystallization of silver(I) chloride from neat piperidine (L) yields a 1 : 2 adduct, characterized by a single-crystal X-ray study. Crystals are monoclinic, C2/c, a 20.76(4), b 6.422(7), c 20.69(2)Ǻ, β 96.9(1)°, Z 8; R 0.042 for 1061 'observed' reflections. The structure, the first determined for a 1 : 2 silver(I) chloride/monodentate amine adduct, is an infinite one-dimensional chloro-bridged polymer -AgL2-Cl-AgL2-Cl-. About the four-coordinate silver atom, Ag-Cl are 2.524(3), 2.667(3)Ǻ, Ag-N 2.385(9), 2.347(11)Ǻ, with Ag-Cl-Ag 102.62(9)°; the largest angle in the silver environment is 120.3(2)°(Cl-Ag-N).

Structure Determinations

Syntheses and room-temperature single-crystal X-ray structure determinations are recorded for 1 : 1 adducts of lead(II) nitrate with the linear multidentate polyamines ethane-1,2-diamine ('en'(= '2')), H2N(CH2)2NH(CH2)2NH2(' dien ' = '22') and H2N(CH2)xNH(CH2)yNH(CH2)zNH2 ( xyztet = '222tet' (= ' trien '), '232tet', '323tet'). Crystal/refinement data are as follows: [(en) Pb (NO3)2](∞|∞) is monoclinic, P 21/c, a 5.388(2), b 12.440(5), c 13.123(3) Ǻ, β 102.33(3)°, Z = 4 f.u .; R 0.037 for No 2698 'observed' (I > 3σ(I)) reflections. [( dien ) Pb (NO3)2](∞|∞) is orthorhombic, Ccma , a 9.800(2), b 10.840(2), c 20.521(5), Z = 8; R 0.045, No 991. [( trien ) Pb (NO3)2](∞|∞) is orthorhombic, P 212121, a 14.815(3), b 10.975(3), c 8.410(2) Ǻ, Z = 4; R 0.050, No 1360; [(232tet) Pb (NO3)2](∞|∞) is isomorphous, a 14.524(6), b 11.221(1), c 8.860(2) Ǻ, R 0.036, No 2371. [(323tet) Pb (NO3)2](∞|∞) is monoclinic, P21/c, a 8.195(4), b 14.407(7), c 13.312(4) Ǻ, β 91.05(3)°, Z = 4; R 0.049, No 1644. In general, the degree of complexity of the adduct diminishes as the ligand size increases: whereas the en adduct is a compact one-dimensional two stranded polymer with nearly all nitrate oxygens involved in tight bridging interactions, the extent of bridging diminishes in the adducts of the larger amines, until, for the 323tet species, a monomer is obtained involving a lead coordination sphere containing the ligand and a pair of bidentate nitrate groups. The 1 : 2 adduct with en is also recorded, and is a dimer with quasi-i internal symmetry. [(en)2Pb(NO3)2]2 is monoclinic, P21, a 6.661(2), b 14.226(8), C 13.618(4)Ǻ, β 96.51(2)°; R 0.072, No 1713.

AbstractThe cyano-bridged heteronuclear coordination polymer of zinc(II)/nickel(II) has been prepared by N-(2-hydroxyethyl)-ethylendiamine (hydet-en), alternatively named 2-(2-aminoethylamino)-ethanol and characterised by IR and thermal analysis. In the bimetallic complex, the decomposition of hydet-en ligands is seen to be endothermic whereas that of the cyano ligands is found to be exothermic. The crystal structure of the complex has been determined by single-crystal X-ray diffraction. The crystal structure of the zinc(II)-nickel(II) complex consists of a one-dimensional polymeric chain –Zn(hydet-en)

A novel Bi (III) coordination compound, [Bi(HQ)(Cl)4]n ((Q = pyridine-4-carbaldehyde thiosemicarbazone), was prepared in this research using a sonochemical technique. SEM, infrared spectroscopy (IR), XRD, and single-crystal X-ray analysis were utilized to analyze the Bi(III) coordination compound. The structure determined using single-crystal X-ray crystallography indicates that the coordination compound is a 1D polymer in solid state and that the coordination number of bismuth (III) ions is six, (BiSCl5), with one S donor from the organic ligand and five Cl donors from anions. It is equipped with a hemidirectional coordination sphere. It is interesting that the ligand has been protonated in the course of the reaction with a Cl- ion balancing the charge. This compound’s supramolecular properties are directed and regulated by weak directional intermolecular interactions. Through π–π stacking interactions, the chains interact with one another, forming a 3D framework. Thermolysis of the compound at 170 °C with oleic acid resulted in the formation of pure phase nanosized Bi (III) oxide. SEM technique was used to examine the morphology and size of the bismuth (III) oxide product produced.
