Structural and spectral studies of diorganotin(IV) complexes containing bis-tridentate N,N-bis(4-oxo-4-phenylbutan-2-ylidene)oxalohydrazide ligand
Original language description
Three new symmetrical binuclear diorganotin(IV) complexes with the symmetrical bis-tridentate Schiff base, N,N-bis(4-oxo-4-phenylbutan-2-ylidene)oxalohydrazide, (R2Sn)2[Ph-C(O)CH-C(Me)N-NC(O)-C(O)N-NC(Me)-CHC(O)-Ph] (R = Ph: Ia; R = Me: Ib; R = n-Bu: Ic)have been synthesized by reaction with corresponding diorganotin(IV) dichloride at room temperature in methanol in presence of triethylamine. The complexes have been characterized by elemental analyses, IR, 1H, 13C, 15N and 119Sn NMR spectroscopy. Two dimensional H,H-COSY, NOESY, H,C-COSY, gs(gradient selected)-HMQC and gs-HMBC techniques were applied in order to assign proton and carbon chemical shifts unambiguously. The ?(119Sn) values for the complexes Ia-Ic are -320.1, -181.9 and -150.7 ppm respectively, indicating pentacoordinated tin centres. The C-Sn-C angles calculated from 1J(119Sn, 13C) for Ia, 1b and Ic are found to be 135.6°, 133.85° and 135.0° respectively. From the 2J(119Sn, 1H) value, the Me-Sn-Me angle for Ib is found t
