The title compound, {[Zn(C9H11N2S2)2]·0.5C6H7N} n , comprises two independent, but chemically similar, Zn[S2CN(Et)CH2py]2 residues and a 4-methylpyridine solvent molecule in the asymmetric unit. The Zn-containing units are connected into a one-dimensional coordination polymer (zigzag topology) propagating in the [010] direction, with one dithiocarbamate ligand bridging in a μ2-κ3 mode, employing one pyridyl N and both dithiocarbamate S atoms, while the other is κ2-chelating. In each case, the resultant ZnNS4 coordination geometry approximates a square pyramid, with the pyridyl N atom in the apical position. In the crystal, the chains are linked into a three-dimensional architecture by methyl- and pyridyl-C—H...S, methylene-C—H...N(pyridyl) and pyridyl-C—H...π(ZnS2C) interactions. The connection between the chain and the 4-methylpyridine solvent molecule is of the type pyridyl-C—H...N(4-methylpyridine).

The reaction of bis(3-oxo-1,3-diphenylprop-1-enolato-κ2 O,O′)zinc(II), [Zn(dbm)2], with tris[4-(pyridin-3-yl)phenyl]amine (T3PyA) in tetrahydrofuran (THF) afforded the title crystalline coordination polymer, {[Zn(C15H11O2)2(C33H24N4)]·C4H8O} n . The asymmetric unit contains two independent halves of Zn(dbm)2, one T3PyA and one THF. Each ZnII atom is located on an inversion centre and adopts an elongated octahedral coordination geometry, ligated by four O atoms of two dbm ligands in equatorial positions and by two N atoms of pyridine moieties from two different bridging T3PyA ligands in axial positions. The crystal packing shows a one-dimensional polymer chain in which the two pyridyl groups of the T3PyA ligand bridge two independent Zn atoms of Zn(dbm)2. In the crystal, the coordination polymer chains are linked via C—H...π interactions into a sheet structure parallel to (010). The sheets are cross-linked via further C—H...π interactions into a three-dimensional network. The solvate THF molecule shows disorder over two sets of atomic sites having occupancies of 0.631 (7) and 0.369 (7).

The asymmetric unit of the title compound, [Pb2(C8H3IO4)2(CH4O)]n, contains two PbIIatoms, two 5-iodoisophthalate (5-IIP2−) ligands and one coordinated methanol molecule. One Pb atom is eight-coordinated, surrounded by seven carboxylate O atoms from five 5-IIP2−ligands and one O atom from the terminal methanol ligand. The other Pb atom is seven-coordinated in a hemidirected geometry, surrounded by seven carboxylate O atoms from five 5-IIP2−ligands. Both Pb atoms are connected by carboxylate groups to form a one-dimensional infinite rod along theaaxis; neighbouring rods are further linked by the aromatic rings of 5-IIP2−to generate the final three-dimensional structure with channels in theadirection. An O—H...O hydrogen bond between the methanol ligand and one of the carboxylate groups of a 5-IIP2−ligand stablizes the three-dimensional framework. Interestingly, a centrosymmetric rhombus-shaped I4unit is formed by four 5-IIP2−ligands, with I...I distances of 3.8841 (8) and 3.9204 (8) Å.

The asymmetric unit of the title compound, 2C18H15Te+·2Br−·C3H6O or Ph3TeBr·0.5Me2CO, contains two crystallographically independent triphenyltelluronium cations, two bromide anions, and one disordered [site-occupancy ratio = 0.581 (7):0.419 (7)] solvent molecule. Interionic Te...Br interactions connect the cations and anions into a tetrameric step-like structure. The primary coordination spheres of both Te atoms are TeC3trigonal pyramids: three short secondary tellurium–bromine interactions expand the coordination geometry of one of the Te atoms to an octahedron. While the other Te atom shows only two Te...Br secondary bonding interactions, it is also six-coordinated due to a Te...π interaction [3.769 (2) Å] with one of the phenyl rings of the adjacent cation.

The title tetranuclear stannoxane, [Sn4(C6H5)8(C6H4NO3)4O2]·1.5CHCl3·solvent, crystallized with two independent complex molecules, A and B, in the asymmetric unit together with 1.5 molecules of chloroform. There is also a region of disordered electron density, which was corrected for using the SQUEEZE routine [Spek (2015). Acta Cryst. C71, 9–18]. The oxo-tin core of each complex is in a planar `ladder' arrangement and each Sn atom is fivefold SnO3C2 coordinated, with one tin centre having an almost perfect square-pyramidal coordination geometry, while the other three Sn centres have distorted shapes. In the crystal, the complex molecules are arranged in layers, composed of A or B complexes, lying parallel to the bc plane. The complex molecules are linked by a number of C—H...O hydrogen bonds within the layers and between the layers, forming a supramolecular three-dimensional structure.

Each metal ion exhibits a distorted tetrahedral coordination geometry consisting of two pyridyl and two benzimidazole N atoms from four distinct ligands. Two metal ions are linked by two bep ligands to form a centrosymmetric 18-memberedM2(bep)2metallacycle, while adjacentM2(bep)2metallacycles are further interlinked by another two bep ligands resulting in a ladder-like array. In the extended structure, four adjacent ladder-like arrays are connected together through C—H...F, O—H...O and C—H...O hydrogen bonds between bep ligands, solvent molecules and counter-anions into a three-dimensional supramolecular structure.

The title coordination polymer, [Cd3Co2(CN)12(C2H8N2)4]n, has an infinite two-dimensional network structure. The asymmetric unit is composed of two crystallographically independent CdIIatoms, one of which is located on a twofold rotation axis. There are two independent ethylenediamine (en) ligands, one of which bis-chelates to the Cd atom that sits in a general position, while the other bridges this Cd atom to that sitting on the twofold axis. The Cd atom located on the twofold rotation axis is linked to four equivalent CoIIIatomsviacyanide bridges, while the Cd atom that sits in a general position is connected to three equivalent CoIIIatomsviacyanide bridges. In this way, a series of trinuclear, tetranuclear and pentanuclear macrocycles are linked to form a two-dimensional network structure lying parallel to thebcplane. In the crystal structure, these two-dimensional networks are linkedviaN—H...N hydrogen bonds involving an en NH2H atom and a cyanide N atom, leading to the formation of a three-dimensional structure. This coordination polymer is only the second example involving a cyanometallate where the en ligand is present in both chelating and bridging coordination modes.

In the crystal structure, the pyridine-2,3-dicarboxylate (pydc2−) ligand exhibits μ3-η1,η1:η1:η1and μ3-η1,η1:η1,η1:η1coordination modes, bridging two FeIIIcations and one SrIIcation. The SrIIcation, which is located on an inversion centre, is eight-coordinated by six O atoms of four pydc2−ligands and two water molecules. The coordination geometry of the SrIIcation can be best described as distorted dodecahedral. The FeIIIcation is six-coordinated by O and N atoms of four pydc2−ligands in a slightly distorted octahedral geometry. Each FeIIIcation bridges two neighbouring FeIIIcations to form a one-dimensional [Fe2(pydc)4]nchain. The chains are connected by SrIIcations to form a three-dimensional framework. The topology type of this framework istfj. The structure displays O—H...O and C—H...O hydrogen bonding.
