The title complex [^n BuSn(O)O2C(OH)CPh2]6.2H2O has been synthesized by the reaction of n-BuSn(O)OH with benzilic acid in 1:1 molar radio and characterized by IR, ^1H NMR spectra and elemental analysis. The crystal structure was determined by X-ray diffraction. It crystallizes in triclinic, space group PI with a = 1.3543(2), b = 1.4593(2), c = 1.5293(2) nm, α = 102.075 (2),β = 115.571 (2), γ = 93.308(3)°, Z = 1, V = 2.6282(7) nm^3, Mr = 2550.21, Dc = 1.611 g/cm^3,μ = 1.477 mm^-1, F(000) = 1280, R = 0.0309 and wR = 0....
