Abstract

Abstract:

Reaction of the N,N,N',N'-p-xylylenediamine tetracetic acid (H$_4$L) with Cu(NO$_3$)$_2$ leads to the formation of a new polynuclear copper complex. Crystal structure of the polynuclear copper complex has been determined. This polynuclear copper complex belongs to the orthorhombic space group Pmn21, and exhibits a novel 3D structure. Rectangular channels with a dimension of 1.105 6 nm$\times$0.696 4 nm, based on the distances of Cu ions, are found in this structure. Additionally, the results of electro spray ionization-mass spectrometry (ESI-MS) spectra and potentiometric measurements show that the polynuclear copper complex exists as a dinuclear species in the solution. The results may provide theoretical basis to potential applications of the polynuclear copper complex in magnetism, catalysis and structural and functional models of metalloenzymes.
