Abstract

In the crystal of [(2-MeO)(5-Cl)C₆H₃]₃Bi (I), obtained from bismuth trichloride and 2-methoxy-5-chlorophenyllithium in ether, bismuth atoms have a trigonal ligand environment. The coordination number of the central atom is 6 (3 + 3), with allowance made for the coordination of the MeO oxygen atom to the metal (the Bi···OMe intramolecular distances are 3.014(6), 3.088(6), and 3.168(6) Å). Treatment of a mixture of I and bromodifluoroacetic acid, or [(2-MeO)(5-Br)C₆H₃]₃Bi and 2,3,4,5-tetrafluorobenzoic acid in ether with tert-butyl hydroperoxide results in the formation of trigonal bipyramidal triarylbismuth dicarboxylates [(2-MeO)(5-Cl)C₆H₃]₃Bi[OC(O)CF₂Br]₂ (II) and [(2-MeO)(5-Br)C₆H₃]₃Bi[OC(O)C₆HF₄-2,3,4,5]₂ (III), respectively, with carboxyl ligands in the apical positions. In the crystals of II and III, the metal atom is additionally coordinated to the oxygen atoms of the O=C and MeO groups (3.05(16), 3.30(16), and 3.153(5)−3.117(5) Å for II and 3.004(7), 3.230(7), and 3.159(7)−3.199(7) Å for III). The structures of I–III were studied by X-ray diffraction (CIF file CCDC nos. 2044006 (I), 2044005 (II), and 2048153 (III)).
