水杨醛甘氨酸还原型希夫碱铜配合物的合成与结构表征

摘要

通过缩合和还原反应合成了还原型希夫碱配体H2SalGly.以H2SalGly、2,2′-联吡啶和醋酸铜为原料合成了配合物[Cu(SalGly)(2,2′-bipy)]·3H2O,并通过溶液挥发法得到了配合物的单晶.利用元素分析、IR及单晶X-衍射仪对所合成配合物的结构进行了表征.结果表明,晶体属单斜晶系,空间群为Cc,Z=4,a=0.528 35(8) nm,b=2.253 9(3) nm,c=1.662 5(3) nm,α=90°,β=98.029(2)°.%Schiff base H2SalGly is synthesized by the condensation and reduction reactions between salicylaldehyde (Sal) and glycine (Gly).The copper complex crystal of [Cu (SalGly)(2,2′-bipy)]·3H2O is synthesized by H2SalGly, 2,2′-bipyridine, and cupric acetate.The single crystal of [Cu (SalGly)(2,2′-bipy)]·3H2O is obtained by vaporizing solvent and its structure characterized by elemental analysis ,IR and X-ray diffraction.The results show that the crystal belongs to monoclinic system and space group Cc, Z=4, a=0.528 35 (8) nm,b=2.253 9 (3) nm,c=1.662 5 (3) nm,α=90°,β=98.029 (2)°.
