Crystal structure and spectral properties of a new type of polymeric complex with 18-membered macrocycles [Nd(C 16H 18S 2O 2) 2(NO 3) 3] n

Abstract

The neodymium nitrate complex with 1,4-bis(phenylsulfinyl)butane(bphsb)[Ln(bphsb) 2(NO 3) 3] n has been synthesized and characterized. The X-ray crystal structure determination of the complex indicates that bphsb and neodymium(III) ion form a polymeric chain involving 18-membered macrocycles, each macrocycle comprising two neodymium(III) ions. The adjacent metal centres are linked by the bridging ligand. Each neodymium ion is ten-coordinated and the coordination geometry is a distorted 4,4-bicapped square antiprism. The IR and absorption spectra of solid and solution for the complex were also studied.
