Crystal structure of bis­{4-bromo-2-[(carb­amim­id­amido­imino)­meth­yl]phenolato-κ(3) N,N′,O}cobalt(III) nitrate di­methyl­formamide monosolvate

The title compound, [Co(C(8)H(8)BrN(4)O)(2)]NO(3)·C(3)H(7)NO, is formed of discrete [CoL (2)](+) cations, nitrate anions and di­methyl­formamide (DMF) mol­ecules of crystallization. The cation has no crystallographically imposed symmetry. The ligand mol­ecules are deprotonated at the phenol O atom and octa­hedrally coordinate the Co(III) atoms through the azomethine N and phenolate O atoms in a mer configuration. The deprotonated ligand mol­ecules adopt an almost planar conformation. In the crystal lattice, the cations are arranged in layers in the ab plane divided by the nitrate anions and solvent mol­ecules. No π–π stacking is observed. All of the amine H atoms are involved in hydrogen bonding to nitrate, DMF or ligand O atoms or to one of the Br atoms, forming two-dimensional networks parallel to (100).
