摘　　要：A novel Ce-containing poly(tungstobismuthate)Cs18Na8H_(2)0[Ce3(H_(2)O)10W8Bi4O_(2)8(B-α-Bi W9O_(3)3)4]2·64H_(2)O(1)has been synthesized by a facile one-pot self-assembly reaction strategy.Its structural characterization is realized by virtue of single-crystal X-ray diffraction,infrared spectroscopy,powder X-ray diffraction and thermogravimetric analysis.The polyoxoanion of 1 is an octameric architecture consisting of two tetrameric entities[Ce3(H_(2)O)10W8Bi4O_(2)8(B-α-Bi W9O_(3)3)4]23-linked by two Ce–O–W bonds,and adjacent polyoxoanions are further combined together by means of Ce3+linkers,resulting in an infinite 1D chain architecture.Compound 1 is the currently largest tungstobismuthate,and also represents the first example of lanthanide-encapsulated tungstobismuthate exhibiting an extended structure.Furthermore,compound 1 as a heterogeneous catalyst,exhibits high activity for the oxidative decontamination of a sulfur mustard simulant,2-chloroethyl ethyl sulfide(CEES)into 2-chloroethyl ethyl sulfoxide(CEESO).
