| Abstract: | The polynuclear complex, [La(bphsb) 2(NO 3) 3] n (bphsb=1,4 bis(phenylsulfinyl)butane) were obtained. The structure of the complex consists of ten coordinated metal ions linked up with six O atoms of the three bidentate nitrates and with four O atoms of the four bphsb ligands. The coordination polyhedron of the La 3 may best be described as distorted bicapped square antiprism. The bphsb ligands act as bridges that join two neighbouring lanthanum ions to give polymeric chains. Each chain contains 18 membered macrocyclic rings with two La atoms. In the complex, the bphsb ligands adopt meso stereoisomer in which sulfur atoms are chiral, and the absolute configurations of the atoms are RS. |
