elemental analysis, UV, IR, and mass spectrometry. Compounds 2a, 2b and 2c were characterized by single-crystal X-ray structure analysis. In the solid state, 2a, 2b, and 2c showed the Schiff bases backbone in a bent arrangement containing a tin atom with distorted octahedral geometry, where the ligand occupies the four equatorial positions and the methyl, n-butyl, or phenyl groups occupy the trans axial positions
