Abstract

The molecular structure of 1,3,5-tris (trimethylstannyl) benzene has been determined by gas-phase electron diffraction. The C-C bond length is in good agreement with that in benzene. In agreement with the somewhat electron-releasing character of the substituents, the endocyclic bond angles at the substituents are somewhat smaller than 120°. The mean value of Sn-C bond lengths is greater than that in tetraphenyltin and tetramethyltin. The SnMe3 groups appear freely rotating around the Caryl-Sn bonds. The following bond lengths (rg) and bond angles were determined: (Sn-C)mean 2.150 ± 0.007 Å, C-C 1.399 ± 0.005 Å, (C-H)mean 1.105 ± 0.006 Å, < C-C(Sn)-C 117.7 ± 1.7°, < Caryl-Sn-Cmethyl 106.7 ± 0.7°, < Sn-C-H 111.5 ± 0.9°.
