A high dimensional copper coordination polymer {[Cu-2(btb)(2)(H2O)(4)(beta-Mo8O26)]center dot H2O}(n) (1, btb = 1,4-bis(1,2,4-triazol-1-yl)butane) based on [beta-Mo8O26](4-) anions and flexible bis(triazole) ligands has been synthesized and characterized by elemental analysis, IR spectra, single-crystal X-ray diffraction and thermal analysis. The crystallographic data show that complex 1 crystallizes in triclinic space group P (1) over bar with a = 9.7550(10), b = 10.3996(11), c = 10.9516(11) angstrom, alpha = 77.622(2), beta = 89.602(2), gamma = 87.610(2)degrees, V = 1084.25(19) angstrom(3), C16H34Cu2Mo8N12O31, M-r = 1785.15, D-c = 2.734 g.cm(-3), mu(MoK alpha) = 3.303 mm(-1), F(000) = 856, GOF = 1.060, Z = 1, the final R = 0.0376 and wR = 0.0982 for I > 2 sigma(I). In 1, the inorganic building block [beta-Mo8O26](4-) anions are connected with each other to generate one-dimensional chains. Then the chains are further connected by Cu2+ ions to form a three-dimensional (3D) inorganic framework [Cu-2(beta-Mo8O26)](n) containing quadrangular channels, with the pcu alpha-Po primitive cubic topology. The btb ligands are encapsulated into the void of the 3D inorganic framework forming a new three-dimensional architecture. The thermal analysis illustrates that complex 1 retains a comparatively good thermal stability.
