Abstract

The title compound, [Co2(C7H4NO4)2(C10H8N2)2(H2O)4](C7H4NO4)2, consists of a centrosymmetric bimetallic complex charge-balanced by free 4-nitro-benzoate anions. The CoII ion exhibits a distorted cis-CoN2O4 octa-hedral coordination environment and the Co⋯Co separation is 3.326 (2) Å. In the crystal, the dications and anions are linked by O-H⋯O and C-H⋯O hydrogen bonds.

Keywords: bimetallic complex; crystal structure; divalent-metal 4-nitro­benzoate; hydrogen bonds.
