Bis(2,2'-bipyridine-κN,N')(3,5-dinitro-2-oxidobenzoato-κO,O)cobalt(II).

In the title compound, [Co(C(7)H(2)N(2)O(7))(C(10)H(8)N(2))(2)], the Co(II) 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 NO(2) groups of the 3,5-dinitro-2-oxidobenzoate ligand.
