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′-NO2C6H4CHNC6H3Me]RTeX2 (R = 4-MeOC6H4, X = Cl, 1a; Br, 1b; I, 1c; R = 4-MeC6H4; X = Cl, 2; R = C6H5, 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.
