    • Synthesis of 1: To a DMF solution (6 mL, pH, 6.5) containing Hade (6.75 mg, 0.05 mmol, octanedioic acid (8.7 mg, 0.05 mmol, and appropriate NaOH (0.1 M) was slowly added a methanol solution (4 mL) of CuCl2 2H2O (34.1 mg, 0.2 mmol) with constant stirring. The resulting mixture was allowed to stir for about 1 h and filtered. Blue block-shaped crystals suitable for X-ray analysis were obtained within 5 days by slow evaporation of the filtrate under an ambient environment. Yield: 60, based on Hade, Anal.

Semiempirical absorption corrections were applied SADABS, and the program SAINT was used for integration of the diffraction profiles. 28 A total of 11 503 reflections up to, 25.03? were collected, of which 4044 unique reflections were used. The structures were solved by direct methods and refined with the fullmatrix least-squares technique using the SHELXS-97 and SHELXL- 97 programs.28
