eng	Structure and solution study of molecular triorganotin compounds containing an N,C,N ligand	The triorganotin compounds R-2(NCN)SnX (NCN = C6H3(Me2NCH2)(2-)2,6(-)) containing different polar groups X or substituents R were prepared. The set of organotin compounds Ph-2(NCN)SnX (X = 1 (2), CF3CO2 (3), CH3CO2 (4), Et2NCS2 (5)) was prepared to study the influence of the polar group X on the character of the Sn-X bond. The effect of substituents R on the character of the Sn-X bond was studied in two additional sets of organotin compounds, R-2(NCN)SnCl (R = Ph (6), Bu (7), Me (8)) and R-2(NCN)SnO2CCH3 (R = Ph (4), Bu (9), Me (10)). The influence of different solvents and temperatures on the presence or absence of covalent Sn-X bonds was studied as well. H-1 and Sn-119 NMR spectroscopy showed the occurrence of dissociation of the Sn-O2CCH3 covalent bond in CD2Cl2 solutions of 4, 9, and 10 at various temperatures (range 300-200 K). The crystal structures of 8 and 10 were studied by X-ray crystallography.
