Structural and spectral studies of 3-(2-hydroxyphenylimino)-1-phenylbutan-1-one and its diorganotin(IV) complexes

Two diorganotin(IV) complexes of general formula R2Sn[Ph(O)CCH-C(Me)N-C6H4(O)] have been synthesized from the corresponding diorganotin(IV) dichlorides and 3-(2-hydroxyphenylimino)-1-phenylbutan-1-one, in methanol. In diphenyltin compound, the central tin atom adopts distorted trigonal-bipyramidal geometry whereas in discrete molecule of dimethyltin compound, the coordination geometry is more square-pyramidal in character.
