Functionalized diorganotelluride and diorganoditelluride: Complexation behaviour as a hybrid (Te, o) ligand

Article abstract of DOI:10.1080/10426509708043568

The ligation of asymmetric diorganotelluride aryltelluroacetic acid (1) with Pd(II) and Pt(II) and bis(5-methyl-2-hydroxyphenyl)ditelluride (2) with Hg(II) and Cu(II) have been studied. In square planar complexes of stoichiometry [MCl(1-H)]₂(M = Pd or Pt) the bidentate uninegative behaviour of 1 has been inferred on the basis of IR ¹H and ¹³C{¹H} NMR. data in conjunction with elemental analysis. The presence of an M-Cl(bridging) vibration band in the IR spectra around 260-270 cm^-1 supports the dimeric formulation of these complexes. In DMSO these chloro bridges are broken which result in lower values for molecular weights in comparison to those calculated on the basis of dimeric stoichiometry. The reaction of 2 with CuCl₂ results in an unusually stable aryltellurenyl chloride. The Te ← O secondary interaction seems to be responsible for its stability. The reaction of HgCl₂ with 2 gives an intricate material of composition ArTeHgCl₂. It seems to be aryltellurenyl chloride which is mercurated at a position orho to the OH group.
