Structure analysis of triaryl derivatives of the group V elements III. Molecular Structure and Spectra of Tris(2,6-Dimethylphenyl)Stibine, C 24H 27Sb

Abstract

X-Ray structure analysis, dipole moment measurement and electronic spectra investigation have been carried out on tris(2,6-dimethylphenyl)stibine. Crystals are monoclinic, a 15.873 Å, b 16.204 Å, c 8.246 Å, γ 103.29°, Z = 4, space group P2 1/ b. The mean value of valence angle CSbC is 104.7°; that of the SbC bonds 2.190 Å. The molecular conformation is governed by steric effects due to the methyl groups. The dipole moment is 0.62 D.
