A wide series of diorganyldiaryloxytelluranes having an azomethine function in the position ortho to the tellurium atom have been synthesized by the reaction of diorganyldimethoxytelluranes with benzilidene-o-aminophenols.The X-ray structural investigation of the dimethylbis<2-(4-nitrobenzylideneimino)phenyloxy>tellurane indicates the presence of an intramolecular coordination bond Te...N.According to the dipole moment data and the 1H, 125Te, 14N NMR spectra, in compounds VII, excluding those having nitor groups in the position para to the CH=N bond, the Te...N coordination is retained in a non-polar solvent (benzene).
