Chiral Schiff-based ligand L-H2vap,derived from the condensation of o-vanillin and L-2-amino-3-phenyl-1-propanol,reacts with Cu(ClO4)2·6H2O,Gd(NO3)3·6H2O and triethylamine in the presence of 4-hydroxybenzoid acid to give L-[Cu4(Hvap)2(vap)2(MeOH)2](ClO4)2·2MeOH·H2O (1).The structure of 1 was characterized by EA,IR,TGA,solid-state CD spectra and the single-crystal X-ray diffraction analyses.The X-ray diffraction analyses reveal that the complex crystallize in the monoclinic system,chiral space group P21 with Z=2,containing a boat-shaped {Cu4O4} structure.Cu4 clusters in 1 are connected through intermolecular hydrogen bonding to form supramolecular chains along b axis.The solid-state CD spectra comfirm the chiral nature of 1.CCDC:883888.
