The Cu (Ⅱ) complex of bis-Schiff base ([Cu (Pioen) H_2O] synthesized from Pio and ethylenediamine (en) and 1,3-propanediamine (tn) Synthesis and Crystal Structure of (ClO_4) _2 and [Cu (Piotn) (H_2O) _2] (ClO_4) 2. Crystal [Pioen] H_2O_3 (ClO_4) _2 belongs to the orthorhombic system. The space group P2_12_12_2, α = 7.9534 (19), b = 7.6768 (48), c = 26.1037 (189), Z = 4, R = , R_w = 0.0771. The crystal [Cu (Piotn) - (H_2O) _2] (ClO_4) _2 belongs to the orthorhombic system with space group P ~ (nam) and α = 7.1360 (24). b = 13.7887 (42), 0 = 22.2556 (81), Z = 4, R = 0.0491, R_w = 0.0491. The structure is solved by the Patterson function and the Fourier synthesis method, and is corrected to convergence by full matrix least square method.
