摘　　要：The title compound of Cu（C14H9O3）2（C5H5N）2（C2H5OH）2（1） was synthesized via the hy- drothermal reaction of CuCl2·2H2O and 9-hydroxy-fluorene-9-carboxylic acid（HHF） with pyridine, and characterized by elemental analysis and infrared spectra. The crystal belongs to triclinic, space group P1 with a = 8.8302（12）, b = 10.1625（14）, c = 12.2708（17）, α = 86.207（2）, β = 69.562（2）, γ = 64.932（2）o, V = 930.3（2） 3, Z = 1, Mr = 764.30, Dc = 1.364 g/cm3, F（000） = 399, S = 1.059 and μ（MoKα） = 0.644 mm-1. The final R = 0.0459 and wR = 0.1274 for 3414 observed reflections with I 〉 2σ（I）. The copper atom is six-coordinated by two oxygen atoms from two different 9-hydroxy-fluorene-9-carboxylate ligands, two pyridine nitrogen atoms and two ethanol oxygen atoms, forming a distorted octahedral coordination geometry. The extensive O–H···O hydrogen bonding connects the molecules to form a one-dimensional chain structure. Between adjacent one-dimensional chains, a two-dimensional layered structure was formed by fluorene ring π-π packing interaction. Between the layers, a three-dimensional structure was formed through the π-π packing interaction of the pyridine ring. Moreover, the thermal stability and photoluminescent property of the complex has been investigated.The title compound of Cu（C14H9O3）2（C5H5N）2（C2H5OH）2（1） was synthesized via the hy- drothermal reaction of CuCl2·2H2O and 9-hydroxy-fluorene-9-carboxylic acid（HHF） with pyridine, and characterized by elemental analysis and infrared spectra.
