Abstract

The title complex, [Co(C(10)H(9)N(4)O(2)S)(2)(C(3)H(7)NO)(2)], lies across an inversion center. The Co(II) atom is coordinated in a slightly distorted octa-hedral geometry by four N atoms from two bidentate 4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidate (sulfadiazine) anions and two O atoms from two dimethyl-formamide (DMF) ligands. The dihedral angle between the benzene and pyrimidine rings is 82.37 (13)°. A three-dimensional network is generated by N-H⋯O hydrogen bonds between the amino groups and of the sulfonamidate O atoms of neighbouring mol-ecules. The DMF ligand is disordered over two sets of sites in a 0.559 (4):0.441 (4) ratio.
