Notes. Crystal structure of biphenyl-2,2′-diyltriphenylantimony

Abstract

An X-ray analysis of the title compound shows slightly distorted trigonal-bipyramidal geometry about the central atom in contrast to the square-pyramidal co-ordination in the related SbPh₅. The heavy-atom method was used with X-ray diffractometer data and refinement by full-matrix least squares converged at R 0.036 for 3 367 reflections. Crystals are monoclinic, space group P2₁/n, with a= 10.488(5), b= 16.561(8), c= 13.503(6)Å, β= 92.16(2)°, and Z= 4.
