Complex of cobalt(II) bromide with hexamethylphosphoric triamide.
The title compound, dibromobis[tris(dimethylamino)phosphine oxide]cobalt(II), [CoBr2(C6H18N3OP)2], displays tetrahedral coordination about cobalt. The molecule has twofold crystallographic site symmetry. The short P-N bonds and the planarity of the dimethylamino groups indicate the importance of dpi-ppi interactions. One of the NMe2 groups has an irregular conformation about the P-N bond and deviates from planarity. It is ascribed to the steric hindrance induced by coordination at the O atom of hexamethylphosphoric triamide.
