| 摘 要： | 1INTRODUCTION Chelidamic acid(2,6-dicarboxy-4-hydroxypyri-dine),an emblematical polydentate ligand,has been of great attraction due to its usage in many areas of science,such as coordinate chemistry,biochemis-try,organic chemistry,medical chemistry and even in HIV investigation1].More and more metal com-plexes containing chelidamic acid ligands have been reported,which play a significant role in de-signing the molecules and extending chemistry of chelidamic acid2].In our previous paper…

| Abstract: | Complex Cu(C7H3NO5)(DMF)(H2O)] was crystallized from the reaction of Cu(CH3COO)2·H2O with 2,6-dicarboxy-4-hydroxypyridine (chelidamic acid) in DMF solution and its structure was characterized by X-ray crystallography. The crystal is of triclinic, space group (P1)with a = 7.835(2), b = 8.594(2), c = 10.309(2)(A),α = 84.16(3), β= 77.94(3), γ= 69.22(3)°, V = 634.4(2) (A)3, Mr = 335.76, Z = 2, Dc = 1.758 g/cm3, λ = 0.71073(A), μ(MoKα) = 1.756 mm-1 and F(000) = 342. The structure was refined to R = 0.0367 and wR = 0.0805 for 2191 observed reflections with I > 2σ(I). The crystal structure shows a distorted square pyramidal geometry around the copper(II) ion, which is chelated by one nitrogen atom and two oxygen atoms of the chelidamic acid, one water molecule and one DMF molecule. The title complex displays 1-D hydrogen-bonded double chains. |
