What is Binuclear copper(I) complexes of some tetradentate pyridyl phthalazines about?

## Binuclear copper(I) complexes of a series of pyridyl phthalazines have been prepared by the reaction of copper(I) salts with the Iigands in acetoninile. The two copper(I) centres are bound to the tetradentate ligands in dimeric or polymeric structures. The complexes are diamagnetic and oxygen sensitive, especially in solution. A binuclear copper(I) complex has been isolated from the ascorbic acid reduced aqueous solution of [Cu,(PAP)(OH)ClJ, (PAP= 1,4di(2'-pyridyl)aminophthalrrzine) which does not contain coordinated ascorbic acid. However aerial oxidation of the ascorbic acid reduced aqueous solution of the same complex produces a binuclear copper species containing one molecule of ascorbate. Aerial oxidation of a dimethylsulfoxide solution of a binuclear copper(I) complex produces a binuclear hydroxy bridged copper species.
