Two unusual copper complexes with nitrilotriacetate and 4,5-diazafluoren-9-one or trans-1,2-bis(4-pyridyl)ethylene mixed-ligands
摘要:
Two unusual copper complexes [Cu(Hnta)(afo)] (1) and [Cu-3(nta)(2)(bpe)(2)(H2O)(4)] (.) bpe (.) 10H(2)O (2) were synthesized and characterized. 1 displays a novel zigzag chain structure via tetradentate Hnta ligands and 2 forms two-dimensional network via hydrogen bonds interactions between the coordination water molecules and nta or free bpe ligands.
