Abstract: Reactions of monofunctional 9,10-phenanthrenequinone monooxime with dialkyl/diaryl-tin dichloride in desired molar ratios in refluxing benzene affords corresponding dialkyl-/diaryl-tin(IV) oximates, which have been characterized by elemental analyses (C, H, N and Sn), IR, multinuclear (1H, 13C and 119Sn) NMR and mass spectroscopy. On the basis of calculation of C-Sn-C bond angle from coupling constant, trigonal-bipyramidal and octahedral geometry are proposed for the chelates 5a-5c and 6a-6c. Semiempirical studies have been carried out to understand the tautomeric and conformational behaviour of the ligand.
