Compound 1 was prepared by laying method, the mixed solution containing 2-[(pyridin-2-ylmethylene)-amino] ethanol (0.1 mmol, 0.0136 g), Cu(ClO4)2 • 6H2O (0.2 mmol, 0.074 g) and pyridine-2-carbaldehyde (0.1 mmol, 0.0107 g) in methanol was carefully layered on the aqueous solution of sodium azide(0.4 mmol, 0.026 g). The single crystals suitable for X-ray diffraction were grown after two weeks. Anal. Calc. for C14H14Cu3.50N27O: H 1.77 C 21.09 N 47.47. Found: H, 1.72; C, 21.65; N, 47.95%.
