【 摘 要 】

The title compound, [Co(C8H8BrN4O)2]NO3·C3H7NO, is formed of discrete [CoL2]+ 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 CoIII 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 networksparallel to (100).
