| Abstrakt: |
The asymmetric unit of [La(C 20 H 21 N 3 O 3 PS) 3 (C 12 H 8 N 2 )] 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-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 Å 3 large voids have been omitted from the refinement model. |
