摘要

Two new lanthanide complexes,[Eu2(Pht)2(HPht)2(Phen)2(H2O)4](1)and [Gd(3-CNC6H4COO)3(H2O)2]n(2)(where Pht2-=dianion of o-phthalic acid,HPht-=mono-anion of o-phthalic acid,Phen=1,10-phenanthroline,3-CNC6H4COO=3-cyanobenzoate)have been synthesized and their crystal structures were determined by X-ray crystallography.The result shows that 1,3-dicyanobenzene was hydrolyzed to give 3-cyanobenzoate under the hydrothermal condition.The compound 2 forms a one-dimensional coordination polymer,whereas the compound 1 is a dimer.The title complex 1 crystallizes in the triclinic system,space group P1,with lattice parameters a=1.01048(6)nm,b=1.06755(7)nm,c=1.19266(8)rim,a=90.188(3)°,β=99.526(2)°,y=100.981(2)°,V=1.24479(14)nm3,Z=1,Dc=1.861 Mg/m3.The title complex 2 crystallizes also in the triclinic system,space group P1,with lattice parameters a=0.93749(9)nm,b=1.14943(10)nm,c=1.27024(11)nm,a=90.188(3)°,β=73.788(5)°,y=86.757(5)°,V=1.19389(19)nm3,Z=2,Dc=1.757 Mg/m3.The photophysical property of 1 has been studied with excitation and emission spectra,which exhibits strong red emission.
