摘要
合成和表征了两个类似的三齿席夫碱配体(L1)-和(L2)-的铜[Ⅱ]配合物[CuL1I](1)和[CuL2I](2)(HL1为2-(2-pyridyl)-N-[1-(1H-pyrrol-2-yl)ethylidene]ethanamine;HL2为N-[1-(1H-pyrrol-2-yl)ethylidene](2-pyridyl)methanamine),并用红外光谱、电喷雾质谱、紫外-可见光谱、单晶X-射线衍射和热重分析等手段对配合物进行了表征。对配合物1的X-射线晶体结构测定表明它是一个畸变的平面正方形单核铜[Ⅱ]配合物。晶体结构还表明,除了配体的柔性和空间限制外,分子间的相互作用也是影响铜[Ⅱ]配合物结构的因素。
Two copper(n) complexes of the homologous tridentate Schiff-base ligands (L1)- and (L2)-, [CuL1I] (1) and [CuL2I] (2), have been synthesised and characterised by IR, ES-MS, UV-Vis, single crystal X-ray diffraction and thermogravimetric analysis ((L1)- and (L2)- are the deprotonated forms of 2-(2-pyridyl)-N-[1-(1H-pyrrol-2-yl) ethylidene]ethanamine (HL1) and N-[1-(1H-pyrrol-2-yl)ethylidene](2-pyridyl)methanamine (HLZ), respectively). X- ray crystal structure determination carried out on 1 reveals that it is a distorted square planar copper(H) monomer. The crystal structure indicates that the intermolecular interaction is also a factor which can influence the structural properties of copper(l/) complexes in addition to ligand flexibility and steric constraints.
