Polymeric cobalt(II) diformate di­methyl­form­amide 0.33-solvate

In the crystal structure of the title compound, poly­[[cobalt(II)-di-μ₃-formato] di­methyl­form­amide 0.33-solvate] [Co(CHO₂)₂]·0.33C₃H₇NO, the units of Co(HCO₂)₂ are assembled into a three-dimensional framework through carboxyl­ate bridging. The four symmetry-independent Co atoms show nearly regular octahedral coordination; two of them lie on inversion centres.
