Synthesis and characterization of two novel potentially tetradentate chelating O^N^C ligands: 2-(2-hydroxyphenyl)-6-p-tolylisonicotinic acid and 2-(2-hydroxyphenyl)-6-p-tolylisonico- tinic acid ethyl ester were firstly reported.

The mono- and binuclear Cu(I) complexes with substituted 2,2’-bipyridine and iodide ligands, [CuL2]BF4 (L=4-methoxycarbonyl-6-(4-methylphenyl)-2,2’-bipyridine (a), 6-(4-hydroxymethylphenyl)-2,2’-bipyridine (b) and 6-(4-methoxylphenyl)-2,2’-bipyridine (c)) and [Cu2(-I)2L2] were prepared, and the crystal structures of the com-plexes were obtained from signal-crystal X-ray diffractional analysis. The spectroscopic properties of the complexes in dichloromethane are dominated by low energy MLCT bands from 360 to 650 nm. The electrochemical studies of mononuclear complexes reveal that the complexes have stable copper(I) state.
