✦ Synopsis

The dinuclear molecule of p-{[(Me 3 Si) 2 CH]Sn(Cl) 2 CH 2 SiMe 2 } 2 C 6 H 4 is centrosymmetric and adopts an `S' conformation that is stabilized by intramolecular CÐHÁÁÁp interactions. The tin atom exists within a distorted tetrahedron defined by a C 2 Cl 2 donor set.

The dinuclear molecule of [(Me 3 SiCH 2 )Cl 2 Sn] 2 (CH 2 ) 3 adopts an extended conformation and features distorted tetrahedral tin centres, with the greatest distortion manifested in the CÐSnÐC angles of approximately 128 °. The distortions are ascribed to the influence of intermolecular SnÁÁÁCl i

## Abstract Each tin atom of the title compound is five‐coordinate, defined by 2C, 2Cl and 1O atoms, and shows a distorted square pyramidal configuration stabilized by intramolecular SnΒ· Β· Β·O or SnΒ· Β· Β·Cl interactions. Both nitrate anions coordinate the tin atoms in a monodentate mode. Copyright Β©
