Polytris­(NN-dimethyl­formamide)(μ4-5-nitro­isophthalato)(μ3-5-nitro­isophthalato)dicobalt(II) NN-dimethyl­formamide monosolvate

摘要

In the polymeric title compound, [Co2(C3H7NO)3(C8H3NO6)2]·C3H7NO, one 5-nitro­isophthalate dianion has its two carboxyl­ate groups chelating to one Co^II 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.
