Tris{N-[bis-(dimethylamino)phosphino-yl]-2,2,2-trichloro-acetamido} (triphenylphosphine oxide)holmium(III)

Abstract

In the title compound, [Ho(C6H12Cl3N 3O2P)3(C18H15OP)], the HoIII 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.
