Penta­aqua­(di­methyl­formamide)­cobalt(II) sulfate di­methyl­formamide monosolvate

The title compound, [Co(C(3)H(7)NO)(H(2)O)(5)]SO(4)·C(3)H(7)NO, contains five aqua ligands, a Co(II) atom, a sulfate ion and both a coordinating and a non-coordinating di­methyl­formamide (DMF) mol­ecule. The DMF solvent mol­ecule lies between the complex units, which are located along the b axis. The sulfate ion is for charge balance. The Co(II) atom has distorted octa­hedral coordination geometry, being ligated by five aqua ligands and the O atom of the DMF ligand. O—H⋯O hydrogen bonds between the aqua ligands and the sulfate anion and non-coordinating DMF molecule lead to the formation of a three-dimensional network. Since all constituents lie on a mirror plane, the H atoms of all methyl groups and of one of the aqua ligands are equally disordered over two positions.
