Academy of Sciences, Fuzhou 350002, China) Abstract:Polymeric cerium nitrate complex with 1,4-bis(phenylsulfinyl)butane (bphsb) [Ce(bphsb)2(NO3)3]n (1) was synthesized and characterized. The crystal structure of the complex indicated that the ligand bphsb and cerium(Ⅲ) ion form a polymeric double-bridge chain complex involving 18-membered macrometallocycles. Each cerium ion is coordinated by ten O......
