Pentaaqua(dimethylformamide)cobalt(II) sulfate dimethylformamide monosolvate

M. Tas, S. Çamur and S. Topal

Abstract: The title compound, [Co(C3H7NO)(H2O)5]SO4·C3H7NO, contains five aqua ligands, a CoII 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 CoII 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.
