Two-Dimensional Neutral Framework Generated from Mixed Organic Ligands: Structure and Magnetic Properties
Abstract:
A new two-dimensional neutral framework generated from mixed organic ligands [Cu3(1,2,4-BTC)2(4,4/-bipy)(H2O)4] (where1,2,4-BTC = 1,2,4-benzenetricarboxylate), has been prepared under hydrothermal condition and characterized by single crystal X-ray diffraction and magnetic susceptibilities. Its structure contains two different one-dimensional chains for the Cu ions, namely [Cu2(1,2,4-BTC)2]n2n- and [Cu (4,4/-bipy)]n2n+, respectively; the carboxylate of 1,2,4-BTC ligands links the two different 1-D chains into a interesting steplike supramolecular neutral framework, which exists ferromagnetic interactions between the copper centers.
