Abstract

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-(dimethyl-amino)phosphino-yl]-2,2,2-trichloro-acetamido ligands (L(-)) and by one O atom from the triphenyl-phosphine oxide ligand, with the formation of a distorted monocapped octa-hedron. In one ligand L(-), the trichloro-methyl group is rotationally disordered between two orientations in a 1:1 ratio, while two dimethyl-amino groups in another ligand L(-) are disordered between two conformations, each with the same 1:1 ratio.
