The 2D-layer compound ([Na2(C8H12N2O3)4(C2H6SO)4(W6O19)]n 1, Mr = 2133.98) synthesized by the reaction of sodium tungstate and barbitone sodium in the solution of DMSO and water has been characterized by IR and Raman spectra, elemental analysis and TGA. X-ray diffrac- tion analysis indicates that Compound 1 crystallizes in the monoclinic system, space group C2/c with a = 14.8026(4), b = 17.3012(3), c = 19.6379(5) ?, β = 98.6300o, V = 4972.4(2) ?3, Z = 4, F(000) = 3928, Dc = 2.851 and μ = 14.101 mm-1. 1 has a two-dimensional layer structure with hexapolyoxotungstate building blocks and coordinated sodium chains.
