摘　　要：A high dimensional copper coordination polymer {[Cu2（btb）2（H2O）4（ -Mo8O26）] H2O}n（1, btb = 1,4-bis（1,2,4-triazol-1-yl）butane） based on [ -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 with a = 9.7550（10）, b = 10.3996（11）, c = 10.9516（11）, = 77.622（2）, = 89.602（2）, = 87.610（2）, V = 1084.25（19）3, C16H34Cu2Mo8 N12O31, Mr = 1785.15, Dc = 2.734 g cm 3, μ（MoKα） = 3.303 mm 1, F（000） = 856, GOF = 1.060, Z = 1, the final R = 0.0376 and wR = 0.0982 for I 〉 2 （I）. In 1, the inorganic building block [ -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 [Cu2（ -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.A high dimensional copper coordination polymer {[Cu2（btb）2（H2O）4（ -Mo8O26）] H2O}n（1, btb = 1,4-bis（1,2,4-triazol-1-yl）butane） based on [ -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.
