[Tc(NO)Cl₂(PPh₃)₂(CH₃CN)] and Its Reactions with 2,2'-Dipyridyl Dichalcogenides.

ABSTRACT: The sparingly soluble technetium(I) complex [Tc^I(NO)Cl₂(PPh₃)₂(CH₃CN)] (1) slowly dissolves during reactions with 2,2'-dipyridyl ditelluride, (2-pyTe)₂, 2,2'-dipyridyl diselenide, (2-pySe)₂, or 2,2'-dipyridyl disulfide, (2-pyS)₂, under formation of deeply colored solutions. Blue (Te compound) or red solids (Se compound) of the composition [{Tc^I(NO)Cl₂(PPh₃)₂}₂{µ₂-(2-pyE)₂}], E = Te (3), Se (4), precipitate from the reaction solutions upon addition of toluene. They represent the first technetium complexes with dichalcogenides. While [{Tc^I(NO)Cl₂(PPh₃)}₂{µ₂
