摘要

A new polyoxometalate (POM)-based compound, {Cu5L4H3W12O40]} [L = 1,6-bis(1,2,4-triazol-1-yl)hexane], has been hydrothermally synthesized and characterized by elemental analysis, IR spectroscopy, UV spectroscopy, X-ray powder diffraction and single crystal X-ray diffraction. In 1, there is a threefold interpenetrating metal-organic network. Furthermore, via sharing Cu cations, the metal-organic networks are fused together by [H3W12O40](5-) (W-12) polyoxoanions to yield a novel 3D POM cluster-organic framework. Additionally, in contrast to free L ligand, compound 1 exhibits an enhanced luminescent property, attributed to an internal heavy metal effect.
