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.

Photocatalysis is a green technology for the treatment of all kinds of contaminants and has advantages over other treatment methods. Recently, much effort has been devoted to developing new photocatalytic materials based on metal–organic frameworks for use in the degradation of many kinds of organic contaminants. With the aim of searching for more effective photocatalysts, the title three-dimensional coordination polymer, [Cd2(C8H4O4)2(C18H16N2O2)]n, was prepared. The asymmetric unit contains one CdIIcation, one benzene-1,2-dicarboxylate anion (denotedL2−) and half of a centrosymmetric 1,4-bis(pyridin-3-ylmethoxy)benzene ligand (denoted bpmb). Each CdIIcentre is five-coordinated by four carboxylate O atoms from twoL2−ligands and by one N atom from a bpmb ligand, forming a disordered pentagonal pyramidal coordination geometry. The CdIIcentres are interlinked byL2−ligands to form a one-dimensional [Cd2L2]nchain. Adjacent chains are further connected by bpmb linkers, giving rise to a two-dimensional network, and these networks are pillared by bpmb to afford a three-dimensional framework with a 33.42.63.71.81topology. Each grid in the framework has large channels which are filled mainly by the two other equivalent frameworks to form a threefold interpenetrating net. The compound exhibits relatively good photocatalytic activity towards the degradation of methylene blue in aqueous solution under UV irradiation.

NiII MOF (I) shows a 4-connected 3D framework with point symbol 66, but is not a typical dia network. ZnII MOF (II) displays a two-dimensional 44-sql network with one-dimensional water chains penetrating the grids along the c direction. The solid-state photoluminescence analysis of (II) was performed at room temperature and the MOF exhibits highly selective sensing toward Fe3+ and Cr2O7 2− ions in aqueous solution.

The synthesis of coordination polymers or metal–organic frameworks (MOFs) has attracted considerable interest owing to the interesting structures and potential applications of these compounds. It is still a challenge to predict the exact structures and compositions of the final products. A new one-dimensional coordination polymer,catena-poly[[[bis{1-[(1H-benzimidazol-2-yl)methyl]-1H-tetrazole-κN3}zinc(II)]-μ-hexane-1,6-dicarboxylato-κ4O1,O1′:O6,O6′] monohydrate], {[Zn(C6H8O4)(C9H8N6)2]·H2O}n, has been synthesized by the reaction of Zn(Ac)2(Ac is acetate) with 1-[(1H-benzimidazol-2-yl)methyl]-1H-tetrazole (bimt) and adipic acid (H2adi) at room temperature. In the polymer, each ZnIIion exhibits an irregular octahedral ZnN2O4coordination geometry and is coordinated by two N atoms from two symmetry-related bimt ligands and four O atoms from two symmetry-related dianionic adipate ligands. ZnIIions are connected by adipate ligands into a one-dimensional chain which runs parallel to thecaxis. The bimt ligands coordinate to the ZnIIions in a monodentate mode on both sides of the main chain. In the crystal, the one-dimensional chains are further connected through N—H...O hydrogen bonds, leading to a three-dimensional supramolecular architecture. In addition, the title polymer exhibits fluorescence, with emissions at 334 and 350 nm in the solid state at room temperature.
