AbstractA heteroleptic silver(I) complex of bis(diphenylphosphano)methane (DPPM) and thiourea (tu) with the formula [Ag2(DPPM)2(tu)3](NO3)2 · 2H2O (1) was prepared and characterized by infrared (IR) and nuclear magnetic resonance (1H, 13C, and 31P) spectroscopic methods, and X-ray crystallography. The crystal structure determination has shown that the complex (1) is dinuclear having each silver(I) ion coordinated by two phosphorus atoms of DPPM molecules and two sulfur atoms of tu ligands adopting a distorted tetrahedral environment. The two silver atoms are bridged by one of the three tu molecules. The other two tu ligands are coordinated in a terminal mode; one with each silver(I) ion. The dinuclear units are associated to each other through hydrogen bonding interactions to form a three-dimensional network in the solid state. Complex 1 showed significant activity against two Gram-negative bacteria (Escherichia coli, Pseudomonas aeruginosa), and molds (Aspergillus niger, Penicillium citrinum), while the activities were poor towards yeasts (Candida albicans, Saccharomyces cerevisiae).

An unexpected trinuclear Co(II) complex, [Co3(L2)2(μ-OAc)2(CH3OH)2]·2CH3OH (H2L2 = 4,4′-dibromo-2,2′-[ethylenedioxybis(nitrilomethylidyne)]diphenol) constructed from a half-Salamo-based ligand (HL1 = 2-[O-(1-ethyloxyamide)]oxime-4-bromophenol) and Co(OAc)2·4H2O, has been synthesized and characterized by elemental analyses, infrared spectra (IR), UV-Vis spectra, X-ray crystallography and Hirshfeld surface analysis. The Co(II) complex contains three Co(II) atoms, two completely deprotonated (L2)2− units, two bridged acetate molecules, two coordinated methanol molecules and two crystalline methanol molecules, and finally, a three-dimensional supramolecular structure with infinite extension was formed. Interestingly, during the formation of the Co(II) complex, the ligand changed from half-Salamo-like to a symmetrical single Salamo-like ligand due to the bonding interactions of the molecules. In addition, the antimicrobial activities of HL1 and its Co(II) complex were also investigated.

In the crystal structure of (4) the selenourea molecules are joined in the shoulder-to-shoulder fashion via N—H...Se hydrogen bonds [N...Se = 3.529 (7) and 3.534 (7) Å] to generate a ribbon and each selenourea molecule also forms a pair of chelating N—H...I hydrogen bonds [N...I = 3.567 (7) and 3.652 (7) Å] to an adjacent iodide ion.

Coarse crystalline (NH2)2(O)P-N=P(NH2)3 is obtained from a NH3 saturated CH2Cl2 suspension of (NH2)2(O)P-N=P(NH2)3 NH4Cl at room temperature. (NH2)2(O)P-N=P(NH2)3·NH4Cl is synthesized by slow addition of Cl2(O)P-N=PCl3 to a solution of NH3 in CH2Cl2 at -78 °C. Excess NH4Cl is removed by treatment with HNEt2 followed by extraction with CH2Cl2. The crystal structure of (NH2)2(O)P-N=P(NH2)3 has been determined by single crystal X-ray methods (P21/c; a = 1462.8(3), b = 944.8(2), c = 1026.9(2) pm, β = 110.69(3)°; Z = 8). In the unit cell there are two crystallographically unique molecules. They form a three dimensional network by intermolecular hydrogen bonding interactions (N-H···N ≥ 313 pm. N-H···O ≥ 293 pm). The investigation of the thermal properties shows decomposition with evolution of NH3 above 80 °C.

The asymmetric unit of the title compound, [Ni(NCS)2(C12H9NO)2(CH3OH)2]·CH3OH, comprises one NiII cation, two thiocyanate anions, two 4-benzoylpyridine coligands, two coordinating, as well as one non-coordinating methanol molecule. The NiII cation is coordinated by two terminally N-bonded thiocyanate anions, the N atoms of two 4-benzoylpyridine coligands and the O atoms of two methanol ligands within a slightly distorted octahedron. Individual complexes are linked by intermolecular O—H...S hydrogen bonding into chains parallel to [010] that are further connected into layers parallel to (10\overline{1}) by C—H...S hydrogen bonds. Additional C—H...O hydrogen-bonding interactions lead to the formation of a three-dimensional network that limits channels extending parallel to [010] in which the non-coordinating methanol molecules are located. They are hydrogen-bonded to the coordinating methanol molecules. X-ray powder diffraction revealed that the compound could not be prepared as a pure phase.

The crystal structure of title salt, C14H36N4 4+·2ClO4 −·2Cl−, has been determined using synchrotron radiation at 220 K. The structure determination reveals that protonation has occurred at all four amine N atoms. The asymmetric unit contains one half-cation (completed by crystallographic inversion symmetry), one perchlorate anion and one chloride anion. A distortion of the perchlorate anion is due to its involvement in hydrogen-bonding interactions with the cations. The crystal structure is consolidated by intermolecular hydrogen bonds involving the 1,4,8,11-tetramethyl-1,4,8,11-tetraazoniacyclotetradecane N—H and C—H groups as donor groups, and the O atoms of the perchlorate and chloride anion as acceptor groups, giving rise to a three-dimensional network.

The crystal structure of title compound, (C14H36N4)[CrO3Cl]2Cl2, has been determined by synchrotron radiation X-ray crystallography at 220 K. The macrocyclic cation lies across a crystallographic inversion center and hence the asymmetric unit contains one half of the organic cation, one chlorochromate anion and one chloride anion. Both the Cl− anion and chlorochromate Cl atom are involved in hydrogen bonding. In the crystal, hydrogen bonds involving the 1,4,8,11-tetramethyl-1,4,8,11-tetraazoniacyclotetradecane (TMC) N—H groups and C—H groups as donor groups and three O atoms of the chlorochromate and the chloride anion as acceptor groups link the components, giving rise to a three-dimensional network.

The reaction of copper(I) iodide withN-acetylthiomorpholine (L, C6H11NOS) in acetonitrile results in a coordination polymer with composition [CuI(L)2]n. The CuIatom is coordinated by two S atoms and two I atoms, adopting a distorted tetrahedral environment. The μ2-bridging mode of the I atoms gives rise to chains extending parallel to [010]. C—H...O hydrogen-bonding interactions between the chains lead to a three-dimensional network.

The 1 : 1 adduct of the a-amino acid glycine with urea has been prepared and its crystal structure determined by X-ray crystallography and refined to a residual R 0·028 for 776 observed reflections. Crystals are monoclinic, pace group P21 with two molecules in a cell of dimensions a 7·364(1), b 4·8703(2), c 8·494(1) Å, β 98·555(7)°. The polymeric structure is based on a primary cyclic hydrogen-bonded nine-membered ring involving both the carboxyl oxygen and an amino hydrogen of the zwitterionic glycine molecule with the urea amine hydrogen and oxygen respectively.

Crystal data: 1, C20H20N16CrK, monoclinic, space group C2/c, a = 1611.2(5), b = 1050.6(3), c = 1609.0(5) pm, β = 91.69(3)°, Ζ = 4 and Rw = 0.037 for 923 diffractometer data; 2, C15H15N15CrRb, monoclinic, space group P21/n, a = 1311.9(3), b = 1139.0(4), c = 1523.3(4) pm, β = 109.39(2)°, Ζ = 4 and Rw = 0.046 for 2336 data.The crystal structure of 1 contains six-coordinated chromium and potassium cations with two pyridine ligands and four µ(1,3) bridging azido groups forming a three-dimensional network structure. The chromium atoms are trans-coordinated by the pyridine ligands, whereas the potassium cations are cis-coordinated. The polymeric complex 2 features di-µ(l,1,3) azido bridged CrRbN2 rings, distorted octahedral chromium(III) coordination geometry, sevencoordinated rubidium, and di-μ(1,3) azido bridges which link the binuclear RbCr(pyridine)3(N3)2 moieties into infinite chains parallel to the b axis.

The monoclinic crystal structure of lithium chromium(III) diphosphate, LiCrP2O7, isotypic with other members of the series LiM IIIP2O7 (M III = Mn, Fe, V, Mo, Sc and In), was refined from laboratory X-ray powder diffraction data using the Rietveld method. The Cr3+ cation is bonded to six O atoms from five diphosphate anions to form a distorted octahedron. Links between the bent diphosphate anions and the Cr3+ cations result in a three-dimensional network, with tunnels filled by the Li+ cations in a considerably distorted tetrahedral environment of O atoms.
