A novel compound, [Co(phen)3][V10O26]·H2O, was hydrothermally synthesized and characterized by single-crystal X-ray diffraction. This compound crystallizes in the orthorhombic space group Ccca with a=13.447(3), b=29.936(6), c=23.252(5) A˚, V=9360(3) A˚3, Z=8 and R=0.0285. Data were collected on a Rigaku R-AXIS RAPID IP diffractometer at 293 K in the range of 1.36<θ<24.99°. The structure of the compound consists of vanadium oxide layers, which are built up from the infinite VO4 chains by corners and edges sharing. The [Co(phen)3]2+ complexes occupy the interlayer space and contact each other via π−π stacking interactions of the phen groups to form infinite one-dimensional chains. [Copyright &y& Elsevier]

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) A˚3, 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. [Copyright &y& Elsevier]
