摘　　要：A novel tetranuclear copper cluster[Cu4(μ-L)6Cl2]was constructed by 2-(1H-pyrazol-3-yl)pyridine(HL)under hydrothermal conditions,and structurally concluded by single-crystal X-ray diffractions,elemental analyses and IR spectra.The title complex 1 was of triclinic system,space group■,C24H18ClCu2 N9,Mr=595.01,a=9.6497(13),b=11.4133(7),c=13.0919(15)?,α=99.166(7),β=108.707(11),γ=111.974(9)°,V=1200.7(2)?3,Z=2,Dc=1.997 g/cm^3,F(000)=706,μ(MoKα)=3.203 nm-1,Rint=0.0404,R=0.0536 and wR=0.1490 for4890 observed reflections with I>2σ(I).In this structure,complex 1 was the unimolecule with unprecedented tetranuclear cluster,which was expanded into a 2D network by wide-ranging C-H…Cl intermolecular hydrogen bonds and further exhibited a 3D supramolecular architecture based onπ-πstacking interactions.In addition,the complex was thermally stable up to 300℃and the solid state fluorescent property of 1 was examined and compared with the ligand.
