The title compound, [{Na（H2O）3}2lRu（dmso）3}2（MoO4）3]·3H2O, has been obtained by the reaction of Na2MoO4·2H2O with cis-Ru（dmso）4Cl2 in aqueous solution. Its crystal structure was determined by single-crystal X-ray diffraction method. The crystal crystallizes in the triclinic system, space group PI^- with a = 12.3333（3）, b = 12.6289（3）, c = 32.0284（14） A, α = 79.873（7）, β= 87.549（9）, γ = 64.500（4）°, V = 4429.5（2） A^3, Z = 4, Mr = 1358.85, Dc = 2.038 g/cm^3, F（000） = 2696 and μ = 1.874 mm^-1. The compound contains a novel pentanuclear triangle bipyramidal core, [{ Ru（dmso）3 } 2（MoO4）3]^2-, which consists of two { Ru（dmso）3 } ^2＋ fragments and three {μ2-MoO4}^2- units. Furthermore, the dmso ligands bridge the pentanuclear [Ru2Mo3] core and two [Na（H2O）3]^＋ fragments together, forming a neutral heptanuclear ruthenium- and sodiumcontaining polyoxomolybdate.

The polyoxometalate（POM）-imidazole ionic liquid（IL） [C8mim]2[Mo6O19]（C8mim=1-methyl-3-octylimi- dazolium） with a low melting point of 82.6 °C was successfully prepared and characterized by FTIR, XPS, NMR, TG and so on. The polyoxomolybdate-based IL has high stability, and its decomposing temperature reaches 321 °C, which is higher than that of 1-alkyl-3-methylimidazolium halides IL. Further photocatalytic performances of the IL were measured via degrading dye rhodamine B（RB） in aqueous solution under the UV light irradiation. The experiments show that the conversion of RB reaches 80.5% after 90 min under UV-light and the degradation efficiency depends on the pH value of the solution, irradiation time and the dosage of the IL and so on.

The polyoxoanion incorporated {Mn（CO）3^＋} complex, （n-Bu4N）2[Mo6O16（OCH3）2{HOCH2C（CH2O）3}2·{Mn（CO）3}2]（1）, has been synthesized by the reaction of （n-Bu4N）4[Mo8O26] with Mn（CO）5Br in methanol, in the presence of C（CH2OH）4. The complex 1 has been characterized by IR, UV-Vis, X-ray single crystal diffraction, and TG. Crystal data for the complex 1：C25H48MnMo3NO16 （1）, Triclinic Pi, a=0.9405（3） nm, b=1.3351（4） nm, c=1.5455（4） nm, α=103.206（5）°, β=102.165（5）°, γ=100.784（5）°, V=1.7896（9） nm^3, Z=2, R1=0.0703, wR2= 0.1495. The structure analysis of complex 1 shows that the complex consists of two tetrabutylammonium cations and a polyoxomolybdate anion that incorporates two fac-Mn（CO）3^＋ units. The anion of complex 1 can be considered as the dimer of two rhomb-like anions by sharing of two comers.

Because of the variable valence of Mo, the challenging research field of polyoxomolybdate possesses extended diverse structures.[1,2] A series of Strandberg-type polyanion [（RP）2Mo5O21]4- have been reported by Pope et al in 1975. [3] In this report, a new derivate of polyoxomolybdate Na7H[Ni{Mo2O6CH3C（O）（PO3）2}2]·28H2O（1）was synthesized and reported, which was characterized by X-ray powder diffraction, IR and UV spectra and single-crystal X-ray diffraction. Single-crystal X-ray structural analysis shows that the same repeating structural subunits {Mo2O6CH3C（O）（PO3）2} are linked into the polyanion [Ni{Mo2O6CH3C（O）（PO3）2}2]8-（1a）（Fig. 1a） by Ni O6 octahedron. Furthermore, the polyanion 1a are extended into 2D-structure（Fig. 1b） and 3D-structure（Fig. 1c）by Na+ ions.
