Abstract

Crystals of tris(<i>N,N</i>-dimethylaminomethyl)phosphine oxide (tmpo) are hexagonal, space group <i>P</i>6<sub>3</sub>; <i>a</i> = 8.723(5), <i>c</i> = 10.636(5) Å, <i>Z</i> = 2, <i>R</i> = 0.039 for 384 observed reflections. The complex [Co(tmpo)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>](ClO<sub>4</sub>)<sub>2</sub>, forms orthorhombic crystals, space group <i>Pbca</i>, <i>a</i> = 19.16(1), <i>b</i> = 10.576(2), <i>c</i> = 117.043(4) Å, <i>Z</i> = 4, <i>R</i> = 0.069 for 1 409 observed reflections. The molecule is centrosymmetric, with the Co atom lying in the center. The tmpo is coordinated through the oxygen atom and one of the nitrogen atoms. The coordination of the ligand brings about very small changes in the bond lengths and angles except for the P=O bond. The coordinated water molecules play a major part in the structure of [Co(tmpo)<sub>2</sub>(H<sub>2</sub>O)<sub>2</sub>](ClO<sub>4</sub>)<sub>2</sub>.
