| Abstract: An organic-inorganic hybrid [Cu2(1,4-bth)3(H2O)( β-Mo8O26)] (1) (1,4-bth=4-(6-(1H-1,2,4-triazol-1-yl)hexyl) -4H-1,2,4-triazole)) based on dimeric copper clusters [Cu2(1,4-bth)3]4+ and [ β-Mo8O26]4- polyanions has been synth-esized and characterized by element analysis, IR spectra, single-crystal X-ray diffraction, thermal analysis. The crystallographic data shows that complex 1 crystallizes in triclinic space group P1 with a=1.195 1(2) nm, b=1.252 0(2) nm, c=2.146 0(4) nm, α=85.893(3)°, β=76.229(3)°, γ=62.714(3)°, V=2.769 0(8) nm3, C30H50Cu2Mo818O27, Mr=1989.48, Dc=2.386 g·cm-3, μ(Mo Kα)=2.598 mm-1, F(000)=1 932, GOF=1.001, Z=2, the final R1=0.062 0 and wR2=0.153 4 for I>2σ(I). In complex 1, each 1,4-bth ligand acted as a tridentate-linker to bridge three Cu2+ ions and dimeric copper clusters [Cu2(1,4-bth)3]4+ were formed. Each dimeric copper cluster is connected to four same clusters forming parallel two dimensional (2D) sheets [Cu2(1,4-bth)3]n4n+. Then the [ β-Mo8O26]4- anions through bonded to the Cu2+ ions as the pillars to construct a three dimensional (3D) framework, with the pcu alpha-Po primitive cubic topology; the thermal analysis illustrate that compound 1 retains a comparatively good thermal stability.
