Synthesis and structure of triphenylbismuth bis(pentachlorobenzoate)

Triphenylbismuth bis(pentachlorobenzoate) has been synthesized by the reaction between triphenylbismuth and pentachlorobenzoic acid in the presence of hydrogen peroxide in ether. According to X-ray diffraction data, the bismuth atoms in two crystallographically independent molecules (A and B) have a distorted trigonal bipyramidal coordination. The OBiO and CBiC angles between axial and equatorial substituents are 171.7(3)A degrees, 173.6(3)A degrees, and 105.3(4)A degrees-146.9(4)A degrees. The Bi-O and Bi-C bond lengths are 2.291(8)-2.315(8) and 2.197(11)-2.204(10) , respectively. The BiaEuro broken vertical bar O(=C) distances are 2.843(10)-2.857(11) .
