Reactions of 2-(hydroxymethyl)pyridine (Hhmp) with PbCl2and Pb(NO3)2at room temperature led to the formation of two novel compounds, namely tetrakis[μ3-(pyridin-2-yl)methanolato]-tetrahedro-tetrakis[chloridolead(II)], [Pb4(C6H6NO)4Cl4], (I), and poly[(μ2-nitrato)[μ2-(pyridin-2-yl)methanolato]lead(II)], [Pb(C6H6NO)(NO3)]n, (II). Compound (I) exhibits a tetranuclear Pb4O4cubane structure, which is connected through π–π stacking interactions between the pyridine groups of the (pyridin-2-yl)methanolate (hmp−) ligands and through C—H...Cl interactions to form an interesting threefold diamondoid network. Compound (II) possesses two-dimensional (4,4)-sql topology based on a Pb2O2unit, which is further extended into a three-dimensional supramolecular network through π–π stacking interactions between adjacent pyridine rings and through C—H...O interactions between the pyridine C atoms of the hmp−ligands and the nitrate anions.

A new 1,3,4-oxadiazole-containing bispyridyl ligand, namely 5-(pyridin-4-yl)-3-[2-(pyridin-4-yl)ethyl]-1,3,4-oxadiazole-2(3H)-thione (L), has been used to create the novel complexes tetranitratobis{μ-5-(pyridin-4-yl)-3-[2-(pyridin-4-yl)ethyl]-1,3,4-oxadiazole-2(3H)-thione}zinc(II), [Zn2(NO3)4(C14H12N4OS)2], (I), andcatena-poly[[[dinitratocopper(II)]-bis{μ-5-(pyridin-4-yl)-3-[2-(pyridin-4-yl)ethyl]-1,3,4-oxadiazole-2(3H)-thione}] nitrate acetonitrile sesquisolvate dichloromethane sesquisolvate], {[Cu(NO3)(C14H12N4OS)2]NO3·1.5CH3CN·1.5CH2Cl2}n, (II). Compound (I) presents a distorted rectangular centrosymmetric Zn2L2ring (dimensions 9.56 × 7.06 Å), where each ZnIIcentre lies in a {ZnN2O4} coordination environment. These binuclear zinc metallocycles are linked into a two-dimensional network through nonclassical C—H...O hydrogen bonds. The resulting sheets lie parallel to theacplane. Compound (II), which crystallizes as a nonmerohedral twin, is a coordination polymer with double chains of CuIIcentres linked by bridgingLligands, propagating parallel to the crystallographicaaxis. The CuIIcentres adopt a distorted square-pyramidal CuN4O coordination environment with apical O atoms. The chains in (II) are interlinkedviatwo kinds of π–π stacking interactions along [0\overline 11]. In addition, the structure of (II) contains channels parallel to the crystallographicadirection. The guest components in these channels consist of dichloromethane and acetonitrile solvent molecules and uncoordinated nitrate anions.

The title compound, C2H10N2 2+·2Cl−·2C12H8N2·4H2O, has an inversion centre located midway between the two C atoms of the ethylenediammonium cation. The 1,10-phenanthroline molecules stack along the a axis, and are linked by π–π stacking interactions to form one-dimensional chains. These are bridged by ethylenediammonium cations, via hydrogen bonds, forming two-dimensional supramolecular sheets parallel to the ac plane. Hydrogen bonds to chloride anions and water molecules connect these two-dimensional sheets, resulting in the formation of a three-dimensional supramolecular network.

The asymmetric unit of compound (I) is composed of two independent cation–anion units of {[Cu(Lpn)2][Fe(CN)5)(NO)]} and two water molecules. The FeIIIatoms have distorted octahedral geometries, while the CuIIatoms can be considered to be pentacoordinate. In the crystal, however, the units align to form zigzag cyanide-bridged chains propagating along [101]. Hence, the CuIIatoms have distorted octahedral coordination spheres with extremely long semicoordination Cu—N(cyanido) bridging bonds. The chains are linked by O—H...N and N—H...N hydrogen bonds, forming two-dimensional networks parallel to (010), and the networks are linkedviaN—H...O and N—H...N hydrogen bonds, forming a three-dimensional framework. Compound (II) is a two-dimensional cyanide-bridged coordination polymer. The asymmetric unit is composed of two chiral {[Cu(Lpn)2][Cr(CN)6]}−anions bridged by a chiral [Cu(Lpn)2]2+cation and five water molecules of crystallization. Both the CrIIIatoms and the central CuIIatom have distorted octahedral geometries. The coordination spheres of the outer CuIIatoms of the asymmetric unit can be considered to be pentacoordinate. In the crystal, these units are bridged by long semicoordination Cu—N(cyanide) bridging bonds forming a two-dimensional network, hence these CuIIatoms now have distorted octahedral geometries. The networks, which lie parallel to (10-1), are linkedviaO—H...O, O—H...N, N—H...O and N—H...N hydrogen bonds involving all five non-coordinating water molecules, the cyanide N atoms and the NH2groups of the Lpn ligands, forming a three-dimensional framework.

In the title compound, [Mn(NO3)2(C12H8N2)2], the MnIIatom lies on a twofold rotation axis, and is six-coordinated in a distortedtrans-N4O2octahedral environment by four N atoms from two 1,10-phenanthroline ligands and two O atoms from two nitrate anions. The nitrate anion is disordered about a twofold rotation axis with fixed occupancy factors of 0.5. In the crystal, molecules are linked by weak C—H...O hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 4.088 (5) Å] into a three-dimensional supramolecular network.

Centrosymmetric Dimers

It has been observed that when electron-rich naphthyl rings are present in chalcones they can participate in π–π stacking interactions, and this can play an important role in orientating inhibitors within the active sites of enzymes, while chalcones containing heterocyclic substituents additionally exhibit fungistatic and fungicidal properties. With these considerations in mind, three new chalcones containing 2-naphthyl substituents were prepared. 3-(4-Fluorophenyl)-1-(naphthalen-2-yl)prop-2-en-1-one, C19H13FO, (I), crystallizes withZ′ = 2 in the space groupP-1 and the four molecules in the unit cell adopt an arrangement which resembles that in the space groupP21/a. Although 3-(4-bromophenyl)-1-(naphthalen-2-yl)prop-2-en-1-one, C19H13BrO, (II), withZ′ = 1, is not isostructural with (I), the molecules of (I) and (II) adopt very similar conformations. In 1-(naphthalen-2-yl)-3-(thiophen-2-yl)prop-2-en-1-one, C17H12OS, (III), the thiophene unit is disordered over two sets of atomic sites, with occupancies of 0.780 (3) and 0.220 (3), which are related by a near 180° rotation of the thiophene unit about its exocyclic C—C bond. The molecules of compound (I) are linked by three independent C—H...π(arene) hydrogen bonds to form centrosymmetric octamolecular aggregates, whereas the molecules of compound (II) are linked into molecular ladders by a combination of C—H...π(arene) and C—Br...π(arene) interactions, and those of compound (III) are linked into centrosymmetric dimers by C—H...π(thiophene) interactions.

Mixed-valence copper(I/II) atoms have been introduced successfully into a Pb/I skeleton to obtain two heterometallic iodoplumbates, namely poly[bis(tetra-n-butylammonium) [bis(μ3-dimethyldithiocarbamato)dodeca-μ3-iodido-hexa-μ2-iodido-tetracopper(I)copper(II)hexalead(II)]], {(C16H36N)2[Cu4 ICuIIPb6(C3H6NS2)2I18]} n , (I), and poly[[μ3-iodido-tri-μ2-iodido-iodido[bis(1,10-phenanthroline)copper(I)]copper(I)copper(II)lead(II)] hemiiodine], {[CuICuIIPbI5(C12H8N2)2]·0.5I2} n , (II), under solution and solvothermal conditions, respectively. Compound (I) contains two-dimensional anionic layers, which are built upon the linkages of CuII(S2CNMe2)2 units and one-dimensional anionic Pb/I/CuI chains. Tetra-n-butylammonium cations are located between the anionic layers and connected to them via C—H...I hydrogen-bonding interactions. Compound (II) exhibits a one-dimensional neutral structure, which is composed of [PbI5] square pyramids, [CuII4] tetrahedra and [CuIIN4I] trigonal bipyramids. Face-to-face aromatic π–π stacking interactions between adjacent 1,10-phenanthroline ligands stabilize the structure and assemble compound (II) into a three-dimensional supramolecular structure. I2 molecules lie in the voids of the structure.
