Two dimethylglyoxime organotin compounds, bis(tri(2-methyl-2-phenylpropyl)tin) dimethylglyoxime complex (C6H5C(CH3)(2)CH2)(3)Sn(ON=C(CH3)C(CH3) =NO)Sn(CH2C(CH3)(2)C6H5)(3) (1) and di(benzyl)tin oxide, chlorine, butanedione oxime multinuclear complex [mu(3)-O-((C6H5CH2)(2)Sn)(2)( ON=C(CH3)C(CH3)= NOH)(O)Cl](2) (2), were synthesized. The compounds were characterized by elemental analysis, IR spectroscopy, NMR (H-1, C-13, and Sn-119), thermogravimetric analysis, and single-crystal X-ray diffraction, and quantum chemical ab initio calculation was performed for their structure and in vitro anticanc...
