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.
