A rare mononuclear alkyldithiolate Cu^II complex characterized by a reversible Cu^II/Cu^I redox couple, compared with its bis([small mu ]-thiolato) dicopper parent complex.

RA: This is one of my dream ligand systems which gives a nice tetrahedral twist when needed and gives high stability to the formed complex due to the chelation. Diphenyl groups attached and the inability to make a complete tetrahedral geometry made this wonderful Cu(II)-bisthiolate complex possible. This is one of the rarest examples of this kind.
