Tris(N-{bis-[meth-yl(phen-yl)amino]-phosphor-yl}benzene-sulfonamidato-?2O,O')(1,10-phenanthroline-?2N,N')lanthanum(III).

ABSTRACT: The asymmetric unit of [La(C20H21N3O3PS)3(C12H8N2)] is created by one LaIII ion, three deprotonated N-{bis-[meth-yl(phen-yl)amino]-phosphor-yl}benzene-sulfonamidate (L-) ligands and one 1,10-phenanthroline (Phen) mol-ecule. Each LaIII ion is eight-coordinated (6O+2N) by three phosphoryl O atoms, three sulfonyl O atoms of three L- ligands and two N atoms of the chelating Phen ligand, leading to the formation of six- and five-membered metallacycles, respectively. The lanthanum coordination polyhedron has a bicapped trigonal-prismatic geometry. 'Sandwich-like' intra-molecular ?-? stacking inter-actions are observed between the 1,10-phenanthroline ligand and two benzene rings of two different L- ligands. The phenyl rings of L- that are not involved in the stacking inter-actions show minor positional disorder. Mol-ecules form layers parallel to the (010) plane due to weak C-H?O inter-molecular hydrogen bonds. Unidentified highly disordered solvate mol-ecules that occupy ca 400?Å3 large voids have been omitted from the refinement model.
