Diethyl Tellurium Morpholine Dithiocarbamate: Synthesis, Structural Elucidation and Te-C bond Cleavage
Abstract: Sulfur-ligated tellurium complexes continue to attract considerable attention owing to their intriguing stereochemical behaviour and supramolecular associations. In this work, diethyl tellurium diiodide, [(C?H?)?TeI?] was reacted with ammonium salt of morpholine dithiocarbamates in dichloromethane. Remarkably, morpholine dithiocarbamates led to Te?C bond cleavage, yielding Te(C?H??NO). The complexes were characterized by elemental analysis, FT-IR, ?H, ??C NMR spectroscopy, and single-crystal X-ray diffraction. Spectroscopic studies confirmed the presence of monodentate dithiocarbamate coordination in the bis-complexes. X-ray analyses revealed that Te(C?H??NO) features Te?H agostic interactions and C?H???O hydrogen bonds leading to a hexameric supramolecular association. These findings provide the structural evidence for Te?C bond cleavage in acyclic diethyl tellurium (IV) systems, highlighting new pathways for organotellurium transformations and supramolecular assembly formation.
