Abstract
Organometallic compounds comprise an important class of antitumor agents. The chemical properties, biological significance, industrial importance and structural characterization of organotin(IV) complexes are well documented. A new Organotin (IV) complex with formula C32H48Cl2N8O12P2 Sn [(4-NO2-C6H4C(O)NH)(OC4H8N)2PO]2Sn(CH3)2Cl2 was synthesized and characterized by IR, 1H, 13C, 31P{1H} NMR spectroscopy and single crystal X-ray diffraction. Single crystal X-ray analysis shows that it belongs to monoclinic system, space group P21/c, with a = 15.9281(10) Å, b = 8.3865(5) Å, c = 15.9242(10) Å, = 103.9340(10)º, Z = 2. The Sn coordination geometry is octahedral. The Sn atom in this compound is located in the inversion center making half of the molecule related by symmetry. The distances Sn-O, Sn-Cl and Sn-C are within expected values. The O-Sn-O angle is trans (180°), but the Sn-O-P angles are about 145°.
