摘　　要：[{Cu（phen）（DMF）2}2（β-Mo8O26）] 1 （C36H44Cu2Mo8N8O30, Mr = 1963.39, phen =- 1,10-phenanthroline） and [Cu（phen）2]2[{Cu（phen）}2Mo8O26] 2 （C72H48Cu4Mo8N12O26, Mr = 2518.90） have been synthesized from （Bu4N）2[Mo6O19], Cu（NO3）2·3H2O and phen using solution method and under solvothermal condition, respectively. Both compounds 1 and 2 are structurally characterized by elemental analyses, IR and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinic system, space group P21/n, with a = 16.3347（13）, b = 9.861（1）, c = 17.2827（14） A, β=99.099（4）°, V= 2748.8（3） A3, Z = 2, Dc= 2.372 g/cm^3, F（000） =1900 and μ= 2.614 mm^-1. X-ray diffraction analysis reveals that compound 1 consists of discrete {[Cu（phen）（DMF）2]2（β-Mo8O26）} clusters constructed from β-[Mo8O26]^4- subunits covalently bound to two [Cu（phen）（DMF）2]^2- coordination groups. Compound 2 crystallizes in the monoclinic system, space group C2/c, with a = 33.1401（9）, b = 16.4508（5）, c = 16.2622（4） A, β= 119.2460（10）°, V = 7735.7（4） A3, Z = 4, Dc = 2.163 g/cm^3, F（000） = 4896 and μ= 2.413mm^-1. X-ray diffraction analysis reveals that compound 2 consists of a centrosymmetric β-octamolybdate-supported complex anion [ {Cu（phen）}2Mo8O26] and two bis-phenanthroline Cu（I） cations.[{Cu（phen）（DMF）2}2（β-Mo8O26）] 1 （C36H44Cu2Mo8N8O30, Mr = 1963.39, phen =- 1,10-phenanthroline） and [Cu（phen）2]2[{Cu（phen）}2Mo8O26] 2 （C72H48Cu4Mo8N12O26, Mr = 2518.90） have been synthesized from （Bu4N）2[Mo6O19], Cu（NO3）2·3H2O and phen using solution method and under solvothermal condition, respectively.
