New Chalcogenide Cobalt Complexes with Diimine Ligands: Synthesis and Crystal Structure

Аннотация

Reactions of a low-valent cobalt complex [Co(nacnac)(η⁶-C₇H₈)] (1) ((nacnac)⁻ = (HC(C(Me)NC₆H₃-iPr₂)₂)⁻) with selenium and tellurium are studied. Two new binuclear complexes [(Co(nacnac))₂(μ,η²-Se₂)] (2) and [(Co(nacnac))₂(μ,η²-Te₂)] (3) have been isolated and characterized. The structures of the complexes are determined by single crystal X-ray diffraction.
