toluene or by reacting Me2SnCl2, LaHNa and LbHNa (1:1:1) in anhydrous methanol. The products were characterized by microanalysis, IR, NMR (1H, 13C, 119Sn) and 119mSn Mössbauer spectroscopy. A full characterization of the structures of the complexes [nBu2Sn(LaH)(LbH)] (1 and 2) and [Me2Sn(LaH)(LbH)] (3) in the solid state were accomplished by single crystal X-ray crystallography. These complexes were found
