Tris(N-{bis-[meth-yl(phen-yl)amino]-phosphor-yl}benzene-sulfonamidato-κ²O,O')(1,10-phenanthroline-κ²N,N')lanthanum(III).

ABSTRACT: The asymmetric unit of [La(C₂₀H₂₁N₃O₃PS)₃(C₁₂H₈N₂)] is created by one La^III 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 La^III 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 π-π stacking inter-actions are observed between the 1,10-phenanthro
