Abstract

Reductive cleavage of C₆F₅SeSeC₆F ₅ with elemental M (M = Zn, Cd, and Hg) in pyridine results in the formation of (py)₂Zn(SeC₆F₅)₂, (py)₂Cd(SeC₆F₅)₂, and Hg(SeC ₆F₅)₂. Structural characterization of the Zn and Cd compounds reveals tetrahedral coordination environments, while the Hg compound shows a complicated series of linear structures with two short, nearly linear Hg-Se bonds, up to two longer and perpendicular Hg· · ·Se interactions, and no coordinated pyridine ligands. All three compounds exhibit well-defined intermolecular π-π-stacking interactions in the solid state. They are volatile and decompose at elevated temperatures to give MSe and either (SeC₆F₅)₂ or Se(C ₆F₅)₂.
