Poly[[tris(N,N-dimethylformamide)(μ4-5-nitroisophthalato)(μ3-5-nitroisophthalato)dicobalt(II)] N,N-dimethylformamide monosolvate]

Abstract

In the polymeric title compound, [Co2(C3H7NO)3(C8H3NO6)2]·C3H7NO, one 5-nitroisophthalate dianion has its two carboxylate groups chelating to one CoII atom while simultaneously coordinating to another metal atom in a μ4-bridging mode. The other 5-nitroisophthalte dianion has one carboxylate group chelating to a metal atom whereas the other bridges two metal atoms in a μ3-bridging mode. Both metal atoms show an octahedral coordination. The polymer adopts a layer motif, with the lattice dimethylformamide molecules occupying the space between adjacent layers.
