摘要
A novel organic-inorganic hybrid compound {[Cu(2,2'-bpy)_2]_2Mo_8O_(26)} hasbeen hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction.The compound crystallizes in the orthorhombic space group, Pna2_1, with a = 2.4164(5), b =1.8281(4), c = 1.1877(2) nm, V = 5.247(2) nm^3, Z = 4, and final R_1 = 0.0331, wR_2 = 0.0727. Thestructure consists of discrete {[Cu(2,2'-bpy)_2]_2Mo_8O_(26)} clusters, constructed from aβ-octamolybdate subunit [Mo_8O_(26)]^(4-) covalently bonded to two [Cu(2,2'-bpy)_2]^(2+)coordination complex cations via bridging oxo groups. In addition, the spectroscopic properties andthermal behavior of this compound have been investigated by spectroscopic techniques (UV-vis, IR,Raman and EPR spectra) and TG analysis.
