【 摘 要 】

A novel supramolecular network containing binuclear copper unit [Cu(phen)₂(�?-IDA)Cu(phen)·(NO₃)](NO₃)· 4(H₂O) (1) was synthesized through the self-assembly of iminodiacetic acid (H₂IDA) and 1,10-phenanthroline (phen) in the condition of pH = 6. It has been characterized by the infrared (IR) spectroscopy, elemental analysis, single crystal X-ray diffraction, and thermogravimetric analysis (TGA). 1 shows a 2-D supramolecular structure assembled through strong and unique �?-�? packing interactions. Density functional theory (DFT) calculations show that theoretical optimized structures can well reproduce the experimental structure. The TGA and powder X-ray diffraction (PXRD) curves indicate that the complex 1 can maintain the structural integrity even at the loss of free water molecules. The magnetic property is also reported in this paper.
