Octahedral and tetrahedral coordination for cobalt(II) in polymeric (₈-benzene-1,2,4,5-tetracarboxylato)bis(N,N-dimethylformamide)dicobalt

Y.-L. Fu, J.-L. Ren and S. W. Ng

Abstract: In the crystal structure of [Co₂(C₁₀H₂O₈)(C₃H₇NO)₂]_n, the tetra-anion uses seven of its eight O atoms to interact with eight Co^II atoms, as one of these seven binds to two metal atoms simultaneously. Four of the eight Co atoms are crystallograpically equivalent and exist in a tetrahedral environment; the other four, which belong to another equivalent set, are each also coordinated by two dimethylformamide molecules in an octahedral environment.
