                                摘要:
                                The preparation of a pentadentate binucleating ligand 2,6-bis[(N-methyl piperazin-1-yl)methyl]-4-cyano phenol (HL) is described together with the corresponding acetato bridged Cu(II) complex [Cu2L-(CH3COO)(2)]CO4. Both the ligand and the complex were characterized by elemental analysis and spectral studies. The electro-chemical behavior of the complex is discussed in detail. A Crystal structure analysis shows that the ligand is pentadentate donating two nitrogens as well as a bridging oxygen to each copper. Two acetates bridge the coppers through axial and apical positions to yield square-pyramidal coppers with a distorted square base. Perchlorates occupy interstitial positions. The structure is held in three-dimensional space by electrostatic attractions and Vander Waals forces. (C) 1998 Published by Elsevier Science Ltd.
