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 unsymmetrical diorganotellurium dihalides [2-(4,4′-NO2C6H4CHNC6H3Me](4-YC6H4)TeX2 (X = Cl, Y = MeO, 1a; Y = Me, 2; Y = H, 3; Y = MeO, X = Br, 1b; I, 1c) were prepared and characterized. Molecular structures of 1a and 1c show scarcely observed 1,4-type intramolecular secondary Te⋯N coordination. Crystal packing of 1c exhibits an unusually rich diversity of intermolecular Te⋯O, Te⋯I and I⋯I interactions while that of 1a shows Te⋯π and π⋯π interactions as the only intermolecular associative forces.
