  Structural investigations of the organoantimony(V) halides Ph4SbX and Ph3SbX2(X = Cl, Br or I) in the solid state and in solution

  摘要：

  X-Ray crystallography revealed a distorted trigonal-bipyramidal structure for Ph(4)Sbl, with Sb-C-ax 2.141(3), Sb-C-eq 2.103(3)-2.117(3) Angstrom and a long Sb-l distance of 3.341(1) Angstrom in monoclinic crystals of P2(1)/n symmetry. Consideration of the weak Sb-X bonds in Ph(4)SbX (X = Cl, Br or I) leads to reassignment of their Raman spectra; Ph(4)Sbl ionises forming [Ph(4)Sb](+) in acetonitrile, as shown by C-13 and Sb-121 NMR spectra. The halide Ph(3)Sbl(2) is reported in two phases, yellow. orthorhombic (Fdd2) crystals isomorphous with Ph(3)SbBr(2) and off-white, cubic (P4(3)32) crystals. In each the molecule is trigonal-bipyramidal. with axial Sb-l bonds of 2.865(1) Angstrom in the former and 2.885(1) Angstrom in the latter, and small differences in their respective bond angles. The phenyl groups of the cubic form are in the regular propeller arrangement whereas one group of the orthorhombic form has a reversed orientation. The vibrational spectra of the two forms differ slightly.

  Arsonium and stibonium cations form contact ion pairs even with very large counterions in chlorohydrocarbons. In the tetraphenyloborates of these cations, the aromatic ring current of the anion phenyl rings causes the NMR signals of protons in α-position of As and Sb t move upfield 1 to 3 ppm. The ion pairs are short-lived so that the B(C6H5)−4 ion has the characteristic properties of an NMR shift

  即使在氯代烃中有非常大的抗衡离子，son和阳离子也会形成接触离子对。在这些阳离子的四苯基硼酸盐中，阴离子苯环的芳环电流使As和Sb t的α位质子的NMR信号向高磁场移动1至3 ppm。离子对被短暂，使得B（C 6 H ^ 5）- 4离子具有NMR位移试剂的特征属性。
