The asymmetric unit of the title compound, poly[{μ(4)-4-[(carboxylatomethyl)sulfanyl]benzoato}(N,N-dimethylformamide)zinc], [Zn(C(9)H(6)O(4)S)(C(3)H(7)NO)](n), consists of one crystallographically independent Zn(II) cation, one 4-[(carboxylatomethyl)sulfanyl]benzoate (L(2-)) ligand and one coordinated dimethylformamide (DMF) molecule. The zinc ion is coordinated by five O atoms from four separate L(2-) ligands and one DMF molecule, and the ZnO(5) unit displays a distorted square-based-pyramidal geometry. Two ZnO(5) units form a binuclear zinc-tetracarboxylate paddlewheel cluster, and these are bridged by L(2-) ligands to generate an intersecting helical chain (Zn(2+) ions as nodes), which is composed of right-handed (P) and left-handed (M) helices. Weak C-H···O hydrogen bonds extend the one-dimensional coordinated chain into a weakly bound three-dimensional supramolecular architecture.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
