    • Complex 1: To the pale-yellow solution containing H 2LCH3 (0.3 g, 1 mmol) and Et3N (0.5 mL) in dry acetonitrile (50 mL) was added [CuI(CH3CN) 4]ClO4 (0.33 g, l mmol, and the solution was refluxed under argon for 0.5 h, upon which the solution turned to red-brown with a copper mirror on the surface of the round-bottomed flask. The solution was cooled and brought to air with stirring for 0.5 h. The precipitated dark-green microcrystalline solid was isolated by filtration and air-dried. Yield: 0.14 g (39, Anal.
