A novel three-dimensional inorganic framework: hydrothermal synthesis and crystal structure of CuMo3O10·H2O

A novel three-dimensional inorganic bimetallic compound Cu[Mo3O10]·H2O 1 has been hydrothermally synthesized and structurally characterized by single-crystal X-ray diffraction. Compound 1 crystallizes in the orthorhombic system, space group Pnma, a=8.6085(17) A, b=7.5822(15) A, c=13.690(3) A, V=893.6(3) A3, Z=4, λ(MoKα) 0.71073 A (R(F)=0.0357 for 1101 reflections). The structure of compound 1 is based on [{Mo3O10}2-]∞ isopolyoxomolybdate chains bonded together with CuO4 tetrahedra into a three-dimensional inorganic open framework. Three types of Mo-Cu layers and one-dimensional tunnels are observed in the title compound
