Polybis­(NN-dimethyl­formamide)(μ-formato)(μ5-4-oxidoisophthalato)dizinc(II)

摘要

The title compound, [Zn2(CHO2)(C8H3O5)(C3H7NO)2]n, is a three-dimensional metal–organic framework, of which two independent Zn^II atoms (denoted Zn1 and Zn2) are linked by both 4-oxidoisophthalate and formate bridging ligands. The 4-oxidoisophthalate ligands link two Zn1-type and three Zn2-type atoms, forming a corrugated sheet roughly parallel to the ac plane. The formate ions join two neighboring sheets along the b axis, forming a three-dimensional network. Two independent dimethylformamide ligands are coordinated to separate Zn^II atoms and fill the voids provided by the framework. Both types of Zn^II atoms have a distorted trigonal-bipyramidal coordination geometry.
