Abstract

Two biphenyl-based N2S2 ligands, 2, 2′-bis-(4-methylimidazol-5-yl) methylsulfanyl) biphenyl (N2S2-mim) and 2, 2′-bis (2-pyridylmethylsulfanyl) biphenyl (N2S2-mpy), have been synthesized and their complexation with copper (II) precursors studied. In order to assess whether the biphenyl ring is influencing the geometry around the copper atom, the NS ligand 1-methyl-4-(2-pyridylmethylsulfanyl) benzene (NS-mpy) and its copper ...
