Bis(2-hydroxybenzoato-O,O')dimethyltin

The Sn atom in [Sn(C₇H₅O₃)₂(CH₃)₂] is in a skew trapezoidal bipyramidal geometry with two types of Sn-O bond distances of approximately 2.1 and 2.5 Å. The methyl substituents lie over the weaker Sn...O interactions. The weakly bonded O atoms are involved in intramolecular hydrogen-bonding contacts with the hydroxyl groups. In addition there is a close intermolecular contact between one of the weakly associated O atoms and a symmetry-related hydroxyl group.
