Abstract:

The dinuclear dichalcogenides [{(C5HR4)NiE}2] (R = CHMe2; E = S (2), Se (3), Te (4)) have been synthesized from [{(C5HR4)NiBr}2] (1) (R = CHMe2) and the corresponding disodium dichalcogenides. Crystal structure analyses show four-membered Ni2E2 rings with weak, but significant E...E interaction. 1-4 Were characterized electrochem. and reveal nickel-centered oxidns., bridging ligand-centered redns., and the formation of mixed-valent Ni(II)/Ni(III) species.
