SYNTHESIS AND CRYSTAL-STRUCTURE OF [TECL2 (NPME(3))(2)](2)

[TeCl2(NPMe(3))(2)](2) has been prepared by the reaction of TeCl4 with Me(3)SiNPMe(3) in acetonitrile solution. The compound forms white moi sture sensitive crystals which have been characterized by IR spectrosc opy and by a crystal structure determination. Space group P2(1)/c, Z = 2, structure solution with 3510 independent reflections, R = 0.029. L attice dimensions at -70 degrees C: n = 1206.0(9); b = 1054.7(7); c = 1156.0(6) pm; beta = 99.27(5)degrees. [TeCl2(NPMe(3))(2)](2) forms cen trosymmetric molecules via TeCl2Te bridges with bond lengths Te-Cl of 267.2 and 366.9 pm, the longer one being in Irans-position to one of t he terminally bounded (NPMe(3)(-)) groups. The TeN bond lengths of 190 .1 and 192.6 pm are unusually short.
