Tris{N-[bis-(dimethyl-amino)phosphino-yl]-2,2,2-trichloro-acetamido}(triphenyl-phosphine oxide)holmium(III).

In the title compound, [Ho(C6H12Cl3N3O2P)3(C18H15OP)], the HoIII 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.
