Abstract

[(2,4,6-Ph3C6H2)Te](2) reacts with iodine affording the aryltellurenic halide (2,4,6-Ph3C6H2)TeI, which is oxidized by oxygen to yield [(2,4,6-Ph3C6H2)Te(mu(2)-O)I](2). It crystallizes with two molecules of dichloromethane in the monoclinic space group P2(1)/c with a unit cell of the dimensions a=911.3(4); b=1153.3(2); c=2244.1(9)pm; beta=93.53(2)degrees, Z = 2). The analogues bromo compound [(2,4,6-Ph3C6H2)Te(mu(2)-O)Br](2) is Obtained by the reaction of [(2,4,6-Ph3C6H2)Te(mu(2)-O)I](2) With NH4Br. It crystallizes with two molecules of xylene in the monoclinic space group P2(1)/n (a = 1067.5(5); b = 1018.4(4); c = 2486.5(8) pm; beta = 101.71(2)degrees; Z=2). Both compounds are built up by two (2,4,6-Ph3C6H2)TeX units (X=Br, I) which are linked by two oxgen bridges to form centrosymmetric molecules. The Te-O-Te angles are 102 degrees. Distinct Te-O bond lengths have been found (191.4(2) and 208.6(2) pm in [(2,4,6-Ph3C6H2)Te(mu(2)-O)I](2) and 189.8(4)/208.4(5) pm inthe bromo compound).
