摘要
A new complex{[Zn2(L)(cpa)2]·H2O}n(1)was prepared under hydrothermal conditions based on 4-carbonylphenylacetic acid(H2cpa)with multi-N-donor ligand 1,4-di(1H-imidazol-4-yl)benzene(L).The complex was characterized by IR spectroscopy,TGA,X-ray powder and single-crystal diffraction.It crystallizes in the orthorhombic system,space group Pbca with a=8.6427(9),b=16.1616(17),c=20.941(2)A,V=2925.0(5)A3,Z=8,C(15)H(13)N2O5Zn,Mr=366.64,Dc=1.665 g/cm^3,μ=1.707 mm^-1,S=1.011,F(000)=1496,the final R=0.0385 and wR=0.0945 for 3360 observed reflections(I>2σ(I)).The central metal Zn(Ⅱ)atom with distorted ZnO3N tetrahedral coordination geometry is four-coordinated by three oxygen and one nitrogen atoms.The cpa^2- ligands connect Zn(Ⅱ)atoms to form two-dimensional(2D)double-layer networks which are further pillared by L ligands into a binodal(3,4)-connected three-dimensional(3D)architecture with a(6^3·10^3)(6^3)tcj/hc topology.Solid-state luminescent property together with quantum yield(QY)and luminescence lifetime is also investigated for compound 1.
