The complexes were synthesized as follows: The ligand (2 molar equivalents) was suspended
in approximately 20 mL of methanol and the suspension heated to boiling. To the boiling mixture
was added, dropwise, a solution of CuCl 2H O (one molar equivalent) in 5 mL methanol. The

yellow mixture was heated at reflux for 2½ - 3h during which time it became a bright orange
color. The reaction mixture was allowed to cool to room temperature and then filtered to collect
a yellow solid. The product was washed with methanol and then a small amount of ether,
followed by drying at the vacuum line.
