摘要： 报道了N-氧化吡啶-2-甲醛(Pio)与乙二胺(en)及1,3-丙二胺(tn)生成的双Schiff碱Cu(Ⅱ)配合物([Cu(Pioen)H2O](ClO4)2和[Cu(Piotn)(H2O)2](ClO4)2)的合成和晶体结构。晶体[Cu(Pioen)H2O3(ClO4)2属正交晶系,空间群P212122,α=7.9534(19)Å,b=7.6768(48)Å,c=26.1037(189)Å,Z=4,R=0.0771,Rw=0.0771。晶体[Cu(Piotn)-(H2O)2](ClO4)2属正交晶系,空间群Pnam,α=7.1360(24)Å。b=13.7887(42)Å,0=22.2556(81)Å,Z=4,R=0.0491,Rw=0.0491。结构由Patterson函数及Fourier合成法解出,经全矩阵最小二乘法修正至收敛。

Abstract: 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)2and 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=7.9534(19)Å, b=9.6768(48)Å, c=26.1037(189)Å, Z=4 , R=0. 0771; CCu(Piotn) (H2O)2](ClO4)2, ortborhombic system, space group Pnam,a=7.1360 (24)Å, 6=13.7887(42)Å.c=22.2556(81)Å,Z=4, R=0.0491. The intensity data were collected on R3m/Efour-circle diffractometer with Mo Ka radiation. The structures were solved by Patterson method and refined by full matrix least-square method.
