摘要	By controlling the metal-ligand ratios, two new Cu(II) coordination polymers based on D-camphoric acid (H(2)DCA) and 1,4-bis(imidazol-1-yl)-butane (bimb), {[Cu-2(DCA)(2)(bimb)(2)(H2O)](2)center dot 7H(2)O}(n) (1), and {[Cu-2(DCA)(2)(bimb)]}(n) (2), have been hydrothermally synthesized and characterized by single-crystal X-ray diffraction, IR and UV-Vis spectra, powder X-ray diffraction. Comparative investigation showed that the different metal-ligand ratios affected the coordination modes of ligand and thus resulted in two distinct structures from 1D chain to 3D network. In 1, the Cu(II) centers are connected by DCA(2-) and bimb into 1D chains, and (H2O)(4) water clusters connect the 1D chains into a 3D supramolecular structure via O-H center dot center dot center dot O hydrogen bonds. Differently, the Cu(II) centers in 2 are bridged by four carboxyl of DCA 2- to form the binuclear paddle-wheel [Cu-2(O2CR)(4)] units, which are pillared by bimb ligands into a 3D framework showing 6-connected pcu topology. Moreover, thermogravimetric and magnetic properties of the two CPs have also been investigated.
