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

In the title compound, [Ho(C(6)H(12)Cl(3)N(3)O(2)P)(3)(C(18)H(15)OP)], the Ho(III) 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.
