N,N,N′,N′-Tetramethylethylenediammonium tetrachloridocobaltate(II)

The asymmetric unit of the title compound, [(CH3)2NH(CH2)2NH(CH3)2][CoCl4], contains a tetrachloridocobaltate(II) dianion and two halves of two centrosymmetric, crystallographically-independent, dications. One independent dication is disordered between two conformations in a 0.784 (13):0.216 (13) ratio. In the crystal, intermolecular N—H...Cl hydrogen bonds link cations and anions into chains propagated in [0overline{1}1]. These hydrogen bonds contribute to the distorted tetrahedral geometry at the CoII atom.
