Bis(2,2′-bipyridine-k2 N,N′)(3,5-dinitro-2- oxidobenzoato-k2 O 1,O 2)cobalt(II)

In the title compound, [Co(C7H2N2O7)(C10H8N2)2], the CoII atom is coordinated by four N atoms from two 2,2′-bipyridine ligands and two O atoms from a 3,5-dinitro-2-oxidobenzoate ligand, displaying a distorted octa-hedral coordination geometry. The crystal structure involves C - H⋯O hydrogen bonds between the 2,2′-bipyridine ligands and the carboxyl-ate and NO2 groups of the 3,5-dinitro-2-oxidobenzoate ligand.
