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, <f>a=8.6085(17)</f> A˚, <f>b=7.5822(15)</f> A˚, <f>c=13.690(3)</f> A˚, <f>V=893.6(3)</f> A˚3, <f>Z=4</f>, <f>λ</f>(MoK<f>α</f>) = 0.71073 A˚ (<f>R(F)</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. [Copyright &y& Elsevier]
