A dialkyltin benzamidoacetate compound {[n-Bu2Sn(O2CCH2NHCOC6H5)](2)O}(2)center dot C6H6 has been synthesized by the reaction of dialkyltin oxide with benzamidoacetic acid in 1:1 molar ratio, and its structure was determined by X-ray single-crystal diffraction. The crystal belongs to orthorhombic, space group Pca21, with a = 1.9134(4), b = 1.9605(4), c = 2.0657(4) run, Z = 4, V = 7.749(3) nm(3), D-c = 1.054 mg.m(-3), mu(MoKa) = 1.337 mm(-1), F(000) = 3576, the final R = 0.0405 and wR = 0.0860. According to the structural analysis, the tin atom adopts a distorted five-coordinate trigonal bipyra...
