| Popis: | The reactions of tris(5-bromo-2-methopxyphenyl)antimony with 2-, 3-nitrobenzaldoximes and 3-fluorophenylacetic acid in the presence of tert-butyl hydroperoxide with the formation of products with the general formula (2-MeO-5-Br-C6H3)3SbХ2, where Х = ONCHC6H4NO2-2 (I), ONCHC6H4NO2-3 (II), OC(O)CH2C6H4F-3 (III), have been studied. According to X-ray diffraction data, complexes I and II crystallize in the form of solvates (with 0.5C6H6 and 2C6H6, respectively). The Sb atoms in molecules of complexes I–III have a trigonal bipyramidal coordination with the carbon atoms of aryl radicals in the equatorial plane and the oxygen atoms of oximate and carboxylate ligands in axial positions. The ОSbО axial angles are 173.47(18)° (I), 170.71(9)° (II), and 173.96(10)° (III), and the OSbC angles variate within 86.2(2)°–95.1(2)° (I), 81.31(13)°–94.35(12)° (II), and 83.12(12)°–96.50(13)° (III). The ranges of Sb–C band lengths are 2.097(6)–2.109(6) A (I), 2.115(4)–2.137(4) A (II), and 2.119(4)–2.122(3) A (III), and the Sb–O bond are 2.050(5), 2.055(5) A (I), 2.058(3), 2.093(3) A (II), and 2.111(3), 2.110(3) A (III). |
