摘要：
Two copper(II) complexes of the homologous tridentate Schiff-base ligands (L-1)(-) and (L-2)(-), [(CuLT)-T-1] (1) and [(CuLI)-I-2] (2), have been synthesised and characterised by IR, ES-MS, UV-Vis, single crystal X-ray diffraction and thermogravimetric analysis ((L-1)(-) and (L-2)(-) 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 (HL2), respectively). X-ray crystal structure determination carried out on 1 reveals that it is a distorted square planar copper(10 monomer. The crystal structure indicates that the intermolecular interaction is also a factor which can influence the structural properties of copper(II) complexes in addition to ligand flexibility and steric constraints.
