【Abstract】 [Cu2L2(H2O)2]·3H2O(H2L=2-[(3,5-Dichloro-2-hydroxy-benzylidene)-amino]-butyricacid) was synthesized using threonine,3,5-Dichloro-salicylaldehyde and copper acetate as raw materials.Elemental analysis,IR spectra,and X-ray single-crystal diffraction were carried out to determine the composition and crystal structure.The results indicate that the crystal structure belongs to monoclinic system,space group P2/1 with a=0.6985(2) nm,b=1.0789(2) nm,c=1.9639(3) nm,β=92.182(3)°,Mr=797.34,V=1.4789(6) nm3,Z=2,Dc=1.790 g/cm3,μ(MoKα)=1.867 mm-1,F(000)=808,the final R=0.0321 and wR=0.0566 for 7629.The Cu(II) atom is coordinated by one N atom,two O atoms of tridentate schiff base ligands and one water molecule,forming square geometry.The asymmetric unit comprises two Cu(II) L(H2O) and three water molecules.The water molecules are linked by hydrogen bonds.更多还原
