Tris{N-[bis(dimethylamino)phosphinoyl]-2,2,2-trichloroacetamido}(triphenylphosphine oxide)holmium(III)

In the title compound, [Ho(C6H12Cl3N3O2P)3(C18H15OP)], the Ho ion is surrounded by six O atoms from the three bidentate N-[bis(dimethylamino)phosphinoyl]-2,2,2-trichloroacetamido ligands (L ) and by one O atom from the triphenylphosphine oxide ligand, with the formation of a distorted monocapped octahedron. In one ligand L , the trichloromethyl group is rotationally disordered between two orientations in a 1:1 ratio, while two dimethylamino groups in another ligand L are disordered between two conformations, each with the same 1:1 ratio.
