Poly[bis(N,N-dimethylformamide)(mu-formato)(mu(5)-4-oxidoisophthalato)dizinc(II)]

초록

The title compound, [Zn-2(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.
