Abstract: | Thirty triorganotin(IV) derivatives of the type R3Sn(R′COCHCOCH2COR″) and [R3Sn]2 (R′COCHCOCHCOR″) (where R = CH3, C2H5, nC3H7, nC4H9 and C6H5 and R′ = R″ = CH3, C6H5 or R′ = C6H5, R″ = CH3) have been synthesised by the interaction of R3SnCl with mono- or disodium salt of 2, 4, 6-heptanetrione, 1-phenyl-1, 3, 5-hexanetrione and 1, 5-diphenyl-1, 3, 5-pentanetrione in 1:1 and 2:1 molar ratios, respectively. The complexes have been examined by their molecular weight, IR, PMR and elemental analyses and their tentative structures assigned. Both “Z” and “E” forms have been identified in the 1:1 complexes in equilibrium with the enol form containing five coordinate tin. The 2:1 derivatives contain one five- and other four coordinated tin(IV) except the phenyl analogue where both the tins are five coordinated. |
