摘要: 以反式-3-[N,N-二(2-吡啶甲基)氨甲基]-2-羟基-5-甲基苯甲醛肟(H₂L)为配体,合成了一个新颖的线性三核铜(Ⅱ)配合物[Cu₃L₂(py)](ClO₄)₂·2THF (1)(py=吡啶,THF=四氢呋喃),对其进行了红外、紫外、热重和单晶结构表征。配合物1属于单斜晶系,空间群为C2/c,a=2.969 0(7) nm,b=1.302 8(3) nm,c=2.057 4(9) nm,β=132.435(2)°,V=5.873(3) nm³,Z=4,R₁=0.047 9。单晶结构表明,这是一个混合桥(-N-O-和μ₂-O-)连的线性五配位三核铜(Ⅱ)配合物:每个铜均由3个氮原子和2个氧原子配位,中间的铜为扭曲的三角双锥构型,而两侧的铜为扭曲的四方锥构型。变温磁化率显示1的铜离子间存在中等的反铁磁性(J=-33.3(5) cm^-1)。

Abstract: A novel trinuclear copper(Ⅱ) complex, [Cu₃L₂(py)](ClO₄)₂·2THF (1) (H₂L=(E)-3-[N,N-di(2-pyridylmethyl)aminomethyl]-2-hydroxyl-5-methylbenzaldehyde oxime, py=pyridine, THF=tetrahydrofuran), has been successfully synthesized and characterized. 1 crystallizes in monoclinic system with space group C2/c, a=2.969 0(7) nm, b=1.302 8(3) nm, c=2.057 4(9) nm, β=132.435(2)°, V=5.873(3) nm³, Z=4 with final R₁=0.047 9. X-ray crystallography analysis reveals that 1 is a mixed-bridged (-N-O-/μ₂-O-) linear tricopper(Ⅱ) complex with all the copper cations being five-coordinated by three N and two O atoms: the central Cu(Ⅱ) in a distorted trigonal bipyramidal configuration, whereas the peripheral Cu(Ⅱ) in a distorted square pyramidal arrangement. Magnetic susceptibility measurement indicates that there is a medium antiferromagnetic exchange coupling between the Cu(Ⅱ) ions with a J value of -33.3(5) cm^-1. CCDC: 916132.
