The interplay of secondary Te?N, Te?O, Te?I and I?I interactions, Te?π contacts and π-stacking in the supramolecular structures of [{2-(4-nitrobenzylideneamino)-5-methyl}phenyl](4- methoxyphenyl)tellurium dihalides

The unsymmetrically substituted diorganotellurium dihalides [2-(4,4′-NO2C6H4CHNC6H 3Me]RTeX2 (R = 4-MeOC6H4, X = Cl, 1a; Br, 1b; I, 1c; R = 4-MeC6H4; X = Cl, 2; R = C 6H5, X = Cl, 3) were prepared in good yields and characterized by solution and solid-state 125Te NMR spectroscopy, IR spectroscopy and X-ray crystallography. In the solid-state, molecular structures of 1a and 1c possess scarcely observed 1,4-type intramolecular Te?N secondary interaction. Crystal packing of these compounds show an unusually rich diversity of intermolecular secondary, Te?O, Te?I and I?I interactions, Te?π contacts as well as extensive π-stacking of the organic substituents.
