Synthesis and structure of triphenylbismuth bis(phenylcarboranylcarboxylate)

Abstract

Triphenylbismuth bis(phenylcarboranylcarboxylate) was synthesized by the reaction of triphenylbismuth with phenylcarboranylcarboxylic acid in the presence of hydrogen peroxide. The bismuth atom has a distorted trigonal-bipyramidal coordination with phenyl ligands in equatorial positions. Bond lengths: Bi-C 2.195(3), 2.196(3), 2.204(3) Å, Bi-O 2.266(2), 2.276 Å. In the molecule there are the donor-acceptor interaction of Bi...O(=C) 2.980(2) and 3.130(3) Å. The value of the equatorial angle CBiC from the side of the Bi...O(=C) contact is 141.4(1)°, the angle OBiO is 168.2(1).
