Cupric complexes of bis-Schiff bases prepared by condensation of pico-linaldehyde N-Oxide(pio) with ethylene diamine(en) and trimethylene diamine(tn) , [Cu(Pioen)H2O](ClO4)2 and CCu(Piotn) (H2O) 2](ClO4)2, were synthesised and their crystal structures were determined. The main crystallographic data are as follows. CCu(Pioen)H2CO(ClO4) 2, ortborhombic system, space group P212121, a = 7.953 4 (19) A, b = 9.676 8(48) A, c = 26.1 03 7 (1 89) A , Z = 4 , R = 0. 077 1; CCu(Piotn) (H2O) 2](ClO4) 2, ortborhombic system, space group -Pnaw,a = 7.1360 (24)A, 6 = 13.788 7(42) A.c = 22.255 6(81) A,Z = 4, R = 0.049 1. The intensity data were collected on R 3m/E four-circle diffractometer with Mo Ka radiation. The structures were solved by Patterson method and refined by full matrix least-square method.
