Abstract

The 119Sn, 15N, 13C and 1H NMR aswell as the solid state 119Sn CP-MAS NMR spectra have been used to study the structures of four diorgano(chloro)tin(IV) oxinates and thiooxinates, (C6H5)2Sn(Cl)(oxin) and R2Sn(Cl)(Txin), where R = benzyl, phenyl, or vinyl groups, oxin = 8-quinolinolate, txin = 8-quinolinethiolate, in deuteriochloroform solution and in the solid state. Both in a non-coordinating solvent (CDCl3) and in the solid state the compounds studied are formed by monomeric molecular chelate complexes with a distorted cis-trigonal bipyramidal arrangement of coordination polyhedra centred on a five-coordinated tin atom. The fine structure of the centre-bands in the 119Sn CP-MAS spectra can qualitatively be explained as result of the combined effect of residual dipolar coupling and scalar interaction of the 119Sn nucleus with two different quadrupolar nuclei (14N, I = 1; 35,37Cl, I = 3 2).
