SYNTHESIS AND STRUCTURE OF [(PH3C6H2)TE]2, [(PH3C6H2)TE(AUPPH3)2]PF6 AND [(PH3C6H2)TEAUI2]2

[(2,4,6-Ph3C6H2)Te]2 reacts with Ph3PAu+ to yield [2,4,6-Ph3C6H2)Te(AuPPh3)2]PF6 which can be oxidized by I2 to form the gold(III) complex [(2,4,6-Ph3C6H2)TeAuI2]2. [(2,4,6-Ph3C6H2)Te]2 crystallizes in the monoclinic space group P2(1)/c with a = 810.6(2); b = 2026.5(5); c = 2260.6(7) pm; beta = 99.23(3)-degrees and Z = 4. In the crystal structure the ditelluride exhibits a dihedral angle C11-Te1-Te2-C21 of 66.1(2)-degrees. The distance Te1-Te2 is 269.45(6) pm. In the cation of the triclinic complex [(2,4,6-Ph3C6H2)Te(AuPPh3)2]PF6 (space group P1BAR; a = 1197.4(3); b = 1457.2(4); c = 1680.0(6) pm; alpha = 84.69(3)-degrees; beta = 85.11(3)-degrees; gamma = 75.54(3)-degrees; Z = 2) a pyramidal skeleton RTeAu2 with distances Te-Au = 259.2(1) and 257.8(2) pm and Au-Au = 295.3(1) pm is present. [(2,4,6-Ph3C6H2)TeAuI2]2 crystallizes in the triclinic space group P1BAR with a = 1086.3(3); b = 1462.9(6); c = 1654.2(2) pm; alpha = 85.25(2)-degrees; beta = 87.44(1)-degree; gamma = 80.90(3)-degrees; Z = 2. In the centrosymmetrical dinuclear complex [(2,4,6-Ph3C6H2)TeAuI2]2 the Au atoms exhibit a square-planar coordination by two iodine atoms and two tellurolate ligands. The tellurolate ligands form symmetrical bridges with distances Te-Au = 260.0 pm. The distances Au-I are in the range of 260.3(1) and 263.7(1) pm.
