The title compound, [Zn(C8H4O4)]n, consists of one ZnIIcation and one benzene-1,2-dicarboxylate dianion (BDC2−) as the building unit. The ZnIIcation is four-coordinated by four carboxylate O atoms from four dianionic BDC2−ligands in a distorted tetrahedral geometry. The ZnIIcations are linked by the BDC2−ligands to generate a structure featuring two-dimensional zinc–carboxylate layers containing left- and right-handed helical chains. The two-dimensional layers are stacked along theadirection. The thermal stability of the title compound has been studied.

The title compound, [Zn(C8H6N4O3)]nor [Zn(L)]n[H2Lis 3-(6-oxo-6,9-dihydro-1H-purin-1-yl)propionic acid], crystallized as a nonmerohedral twin. The ZnIIcation is four-coordinated, ligated by two carboxylate O atoms from twoLligands and two N atoms from another two ligands. Each ligand bridges four ZnIIcentres, extending the structure into a three-dimensional polymer with a 4-connected (65,41) topological structure containing two-dimensional homochiral layers constructed from one-dimensional metal–organic helices. Investigation of the thermal stability of the compound shows that the network has very high thermostability and is stable up to 720 K.

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 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.
