    • Preparation of complexes 1 and 2: A methanolic solution (10 mL) containing copper(II) nitrate trihydrate (48 mg, 0.2 mmol) was mixed with an aqueous solution of sodium azide (130 mg, 2 mmol) dissolved in a minimum of water, R)-phea (11 mg, 0.1 mmol) in 3 mL of water was added to this reaction mixture with continuous stirring. The resulting dark-green solution was filtered and left to stand at 5°C. Brown plate-shaped crystals of 1 suitable for X-ray diffraction were obtained by slow evaporation of the solvents within 2 weeks. Complex 2 was obtained using a method similar to that of 1, except that (S)-phea was used. Yield: 54, Elem anal. Calcd for C16H22-Cu3N20: C, 28.05; H, 3.24; N, 40.89.
