摘要:
The Mannich condensation of formaldehyde with some amines and imidazoles rendered four bis-imidazole ligands in a very simple one pot reaction. The X-ray structures of four copper(II) compounds, obtained with these ligands, show in all cases the copper(II) ions to be in a square pyramidal environment. Three compounds appeared to be mononuclear, while the least bulky ligand rendered a dinuclear complex. (C) 2003 Elsevier B.V. All rights reserved.
