Abstract
A novel cluster organic framework, Er3Cu5I4L10(H2O) (1, L = 4-pyridin-3-yl-benzonate), has been hydrothermally made and structurally characterized by single crystal X-ray diffraction. Structure analysis shows [Er3(COO)6]3+ (Er3) clusters are linked by carboxylate groups generating one dimensional wave-like chain, which further extended by Cu5I4 + (Cu5) clusters into three dimensional heterometallic cluster organic framework. From the perspective of topology, such framework defines a new (7,9)-connected net, considering Er3 and Cu5 cores as the nodes. Furthermore, the elemental analysis, powder X-ray diffraction, infrared spectra and thermogravimetric analysis are also studied.
