  Abstract:   Heteroleptic diorganochalcogen compounds of type R[2-(Me2NCH2)C6H4]E [R = (phtz)CH2, E = Se (1), S (2); R = (4-Cl-phtz)CH2, E = S (3); R = (pz)CH2CH2, E = Se (4)] were prepared by reacting 2-(Me2NCH2)C6H4ELi with the appropriate organic halide in a 1:1 molar ratio. The new compounds were investigated in solution by 1H, 13C and 77Se NMR where appropriate. For compounds 1 and 4 the crystal and molecular structures were determined by single-crystal X-ray diffraction.

Keywords: Diorganoselenium compounds, hypercoordination, structure elucidation
