Abstract:Tripheylbismuth bis(trichloroacetate) (I), triphenylbismuth bis(chloroacetate) (II), and triphenylbismuth bis(bromoacetate) (III) were synthesized by the reaction of triphenylbismuth with carboxylic acid. The Bi atoms of the synthesized compounds have a distorted trigonal-bipyramidal coordination with phenyl ligands in equatorial positions. The Bi-C bond lengths lie within intervals 2.194(2)–2.201(2), 2.193(8)–2.223(7), 2.191(4)–2.220(3) Å, the distances Bi-O and Bi···O(=C) are equal 2.308(2), 2.315(2), and 2.896(2), 2.931(2); 2.289(6), 2.302(6), and 2.891(6), 2.910(6); 2.295(3), 2.312(3), and 2.893(3), 2.920(3) Å in I, II, and III, respectively. Molecules of triphenylbismuth dicarboxylates show linear dependence between the maximum equatorial angle CBiC (on the side of a contact) and intramolecular distance Bi···O(=C).
