In the two-dimensional title coordination polymer, [Zn(C8H4O4)(C14H14N4)] n , the ZnII atom adopts a distorted tetrahedral geometry, being ligated by two O atoms from two different benzene-1,3-dicarboxylate dianions and two N atoms from two symmetry-related 1,2-bis(imidazol-1-ylmethyl)benzene molecules. The dihedral angles between the imidazole rings and the benzene ring in the neutral ligand are 76.31 (13) and 85.33 (15)°. The ZnII atoms are bridged by dicarboxylate ligands, forming chains parallel to the a axis, which are further linked by 1,2-bis(imidazol-1-ylmethyl)benzene molecules, generating a two-dimensional layer structure parallel to the ac plane. The crystal structure is enforced by intralayer and interlayer C—H...O hydrogen bonds.

In the title compound, {[Ag(C29H25N3)2]NO3·CH3OH·H2O}n, the AgIcation is four-coordinated by two pyridine N atoms and two imidazole N atoms from four individual 4-(1-(5′-isopropyl-[1,1′:3′,1′′-terphenyl]-2′-yl)-1H-imidazol-2-yl)pyridine (i-pro-pyim) ligands. This gives rise to a highly distorted tetrahedral geometry with bond angles falling in the range 100.33 (19)–122.76 (19)°. Two crystallographically independenti-pro-pyim ligands (AandB) adopt very similar conformations to one another, such that the dihedral angles between the pyridyl and imidazolyl rings in the two ligands are 40.7 (3) and 42.2 (3)°, respectively. Eachi-pro-pyim ligand binds two symmetry-related Ag+cations, leading to the formation of 14-membered cyclic dimers, in which the AgIatoms are separated by 6.963 (2) Å for the Ag–A2–Ag dimer and 7.020 (2) Å for Ag–B2–Ag. These cyclic dimers are alternately connected to each other by sharing AgIatoms, resulting in the formation of a looped-chain structure extending along the [100] direction. Moreover, adjacent looped chains are connected by intermolecular π–π interactions [centroid-to-centroid distance = 3.689 (4) Å], giving rise to the formation of a two-dimensional supramolecular network propagating parallel to (110). Several intermolecular C—H...O and O—H...O hydrogen bonds further contribute to the stabilization of the crystal structure.

In the title complex, [Cu(C13H8NOS)2], the CuIIatom is coordinated by two N atoms and two O atoms from two bidentate benzothiazolphenolate ligands, forming a distorted tetrahedral geometry [dihedral angle between two N—Cu—O planes: 45.1 (2)°]. The dihedral angles between the benzothiazole ring systems and the phenol rings are 4.1 (4) and 5.8 (4)°, indicating an almost planar geometry. Weak intra- and intermolecular C—H...O hydrogen bonds are observed. In the crystal, weak π–π interactions between aromatic and thiazole rings [centroid–centroid distances = 3.626 (3) and 3.873 (3) Å] link the molecules into a two-dimensional supramolecular network along thebcplane.

In the title coordination polymer, [Ag2(C4H4O4S)], each AgIcation is four-coordinated by three of the four carboxylate O atoms and the S atom from symmetry-related sulfanediyldiacetate ligands, thus defining a distorted tetrahedral geometry at the metal centre. The AgIcations are bridged by sulfanediyldiacetate groups, leading to a two-dimensional layer structure. These layers are interconnectedviaAg—S bonds to form a three-dimensional coordination polymer network overall.

The ZnIIions are bridged by Hbtc2−and bmi ligands, leading to a 4-connected two-dimensional network with the topological notation (44.62). Adjacent layers are further connected by 12 kinds of hydrogen bonds and also by π–π interactions, resulting in a three-dimensional supramolecular architecture in the solid state.
