THE CRYSTAL-STRUCTURE OF DI-2-AMINOPYRIMIDINIUM TETRAPHENYLDICHLORO(MU-OXO)DISTANNATE

Hydrolysis of diphenyltin dichloride in the presence of diethyl ether proceeds via formation of an ionic, monomeric diorganodistannoxane com pound. The single-crystal X-ray diffraction study of (C4H6N3)(2)[SnPh( 2)OCl](2) is reported, together with IR data. The dimer consists of fi ve coordinate tin(IV) units with di-mu-oxo bridging. The coordination geometry of the tin unit is a distorted trigonal bipyramid with two ph enyl groups and one mu-oxo in equatorial positions, and the other two mu-oxo and chlorine atoms in axial positions.
