Copper ion mediated selective cleavage of C-S bond in ferrocenylthiosemicarbazone forming mixed geometrical [(PPh3)Cu(μ- S)2Cu(PPh3)2] having Cu2S 2 core: Toward a new avenue in copper-sulfur chemistry

Unprecedented selective cleavage of the carbon-sulfur bond of the ferrocenylthiosemicarbazone moiety has been observed for the first time, resulting in the formation of mixed geometrical binuclear copper complex [(PPh₃)Cu(μ-S)₂Cu(PPh₃)₂]. Upon trying direct synthesis of the title complex, an unusual tetranuclear [Cu ₄(μ₃-Cl)₄(PPh₃)₄] cubane resulted.
