โœฆ Synopsis

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 CรSnรC angles of approximately 128 ยฐ. The distortions are ascribed to the influence of intermolecular SnรรรCl interactions.

## Abstract Each tin atom of the title compound is fiveโ€coordinate, defined by 2C, 2Cl and 1O atoms, and shows a distorted square pyramidal configuration stabilized by intramolecular Snยท ยท ยทO or Snยท ยท ยทCl interactions. Both nitrate anions coordinate the tin atoms in a monodentate mode. Copyright ยฉ
