✦ Synopsis

The crystal and molecular structures of tris(panisyl)tin acetate (1) (p-anisyl =p-methoxyphenyl) and trimesityltin acetate (2) (mesityl= 2,4,64rimethylphenyI) have been determined. Both have monomeric structures with the acetate group acting as an asymmetric bidentate ligand. Bond valence analysis of (1) and (2) and other Ph,Sn02CR suggest however that the carboxylate ligand effectively occupies a single bonding position at tin. Thus in (1) and (2) the tin atom is in a chemical environment equivalent to that found in four-coordinate R,Sn-X systems based on tetrahedral geometry.
