Summary, etc. Dissolution of a fine powder obtained by grinding of cobaltous carbonate with 4-nitrobenzoic acid (4-nbaH) in hot dimethylsulfoxide (DMSO) followed by slow evaporation of the solvent resulted in the formation of <em>cis</em>-diaquabis(dimethylsulfoxide)4-nitrobenzoatocobalt(II) 4-nitrobenzoate <strong>1 </strong>in good yield.  The title compound [Co(H<sub>2</sub>O)<sub>2</sub>(DMSO)<sub>2</sub>(4-nba)]4-nba <strong>1</strong> crystallizes in the centrosymmetric monoclinic <em>P2<sub>1</sub>/c</em> space group and its structure consists of two crystallographically independent Co(II) ions. Each unique cobalt exhibits octahedral geometry and is bonded to a pair of terminal aqua ligands situated<em> cis</em> to each other and a bidentate 4-nba ligand which form the square base of the octahedron. A pair of DMSO ligands disposed <em>trans</em> to each other complete the hexa coordination around the central metal. The [Co(H<sub>2</sub>O)<sub>2</sub>(DMSO)<sub>2</sub>(4-nba)]<sup>+</sup> cations and the 4-nba anions are interlinked with the aid of several weak H-bonding interactions. A comparative study of 4-nitrobenzoate compounds of cobalt is described.
