This study presents results on synthesis and crystal structure of a new hydrated bismuth(III) oxalate : Bi2(C2O4)3,6H2O. This compound is obtained by precipitation from Bi(NO3)3 solution and oxalic acid. Its structure is determined by X-ray crystallographic analysis from a single crystal: it is monoclinic with a = 9.761(1)Å, b = 8.193(1)Å, c = 10.214(1)Å, $\beta$ = 99.66(1)$^{\circ}$, G.S. P21/n. Its chemical composition is confirmed by chemical analyses, FTIR and TG-DTA experiments.
