| Abstract: A supramolecular compound [Cu(sala)(4,4′-bipy)2]·0.5(4,4′-bipy)·2H2O (sala=N-(2-hydroxybenzyl)-DL-alaninate, 4,4′-bipy=4,4′-bipyridine) was synthesized and characterized by elemental analysis, IR, and the crystal structure was determined by X-ray diffraction technique. It crystallizes in orthorhombic system with space group Pbca. The crystal data are: a=1.877 7(3) nm, b=1.636 7(2) nm, c=2.149 8(2) nm, and V=6.606 9(10) nm3, Z=8, Dc=1.374 g·cm-3, μ=0.713 mm-1, F(000)=2 848, R1=0.044 6, wR2=0.105 7. In the title complex, Cu(Ⅱ) ion is five coordinated with distorted square pyramid configuration. The complex formed three-dimensional porous supermolecular structure through π-π stacking and hydrogen bonds. There exist uncoordinated 4,4′-bipy molecules in the compound, exhibiting a certain inclusion phenomenon. CCDC: 648620. |
