Supramolecular assemblies of organotellurium(IV) dithiocarbamates and third order nonlinear optical susceptibility (χ(3)) of C4H7(CH3)Te[S2CN(C2H5)2]2

Synthesis of supramolecular assemblies of organotellurium(IV) dithiocarbamates, formed through intramolecular Te⋯S secondary bonds, intermolecular Te⋯X (X = I, S) secondary bonds and C–H⋯O hydrogen bonds are described. The supramolecular assemblies containing diethyldithiocarbamate group may serve as possible “rescue agents”. The third order nonlinear optical susceptibility of the organotellurium(IV) diethyldithiocarbamate C4H7(CH3)Te[S2CN(C2H5)2]2 (1) has been studied by degenerate four wave mixing technique using a picosecond laser. It is found to exhibit efficient third-order nonlinear optical susceptibility (χ(3)) of 7.21 × 10−14 esu and second order hyperpolarizability (γ) of 4.88 × 10−32 esu.
