摘要
牛磺酸缩2-吡啶甲醛席夫碱与高氯酸铜在50%甲醇中反应合成了一个新型五配位的双核铜配合物{[Cu2(C8H9N2SO3)2·(H2O)]2·2ClO4(1)},其结构和表面光电性能经IR,元素分析,XRD,UV-Vis和SPS表征。1属单斜晶系,空间群C2/c,晶胞参数a=24.563 0(2),b=9.086 3(6),c=13.099 0(10),β=111.775(3)°,V=2 714.9(4)3,Z=4,Dc=1.929 g·cm-3,μ=2.0 mm-1,F(000)=1 592,R1=0.042 5,ωR2=0.113 9。1的中心金属铜离子与席夫碱配体的2个N和2个O原子以及水分子的O原子配位,形成1个五配位的四方锥结构。由配位水分子,没参与配位的磺酸基氧,高氯酸根形成的氢键以及吡啶环间的π┈π相互作用,把配合物堆积成二维超分子层状结构,稳定了整个晶体结构。1在300 nm^800 nm有正光伏响应,与SPS结论一致。
A novel binuelear copper ( lI ) complex { [ Cu2 ( C8 H9N2S03 )2 ·( H2O) ]2 ·2ClO4 ( 1 ) } was synthesized by reaction of copper perchlorate and ligands with taurine condensation 2-pyridineear- boxaldehyde Schiff base in 50% ethanol water solution. The structure and surface photoelectric prop- erties were characterized by IR, elemental analysis, XRD, UV-Vis and SPS. 1 belongs to monoclin- ie, space groupC2/cwitha=24.563 0(2)(A),b=9.086 3(6)(A),c=13.0990(10)(A),β=111.775(3)°,V=2714.9(4)(A)3,Z=4,Dc=1.929 g.cm-3,μ=2.0 mm-1,F(000) =1 592,R1=0.042 5,ωR2=0.113 9.1. The central Cu( 11 ) atom adopts five eoordintaed with two N and three 0 atoms of the ligands from taurine Sehiff base and one water molecule, leading to a square pyramidal geometry. 1 form two dimensional sheet fragments through 0 - H----O hydrogen bonds of thecoordinating water, uncoordinated-sulfonate, perchlorate anions and π ,π interaction with pyridine rings, and stabilizing the packing. 1 exhibited positive surface photovoltage responses in 300 nm - 800 nm. Associated with UV-Vis, the PSP is consistent with it basically.
