Summary:

In normal conditions, the synthesis of 1 have not been reported in polyoxometalate cluster compounds by elemental analysis, IR, TG and single crystal X-ray diffraction on the crystal structure were characterized.

Structure of compound 1 is based on the Anderson anion [Cr (OH) 6Mo6O18] 3 - one-dimensional chain structure compounds. Formula: [Cu (C10N2H8) 2 (H2O)] 2 {[Cu (C10N2H8)] [Cr (OH) 6Mo6018] 2} · 10H20 (1). X-ray diffraction results show that: Compound (1) is monoclinic, P21 / n space group; cell parameters a = 1.4569 (2) nm, b = 3.4591 (5) nm, c = 1.5088 (2) nm, α = 90 °, β = 111.453 (2) °, γ = 90 °, V = 7.0771 (18) nm3, Z = 4, R1 = 0.0743, ωR2 = 0.1916. Crystal structure analysis shows that the compound is a 1D chain compound, alternately connected by the 2,2 '- pyridine complexes of copper and anions [Cr (OH) 6Mo6O18] 3 - form. Adjacent http://www.chinamagnets.biz/ chains through the pyridine ligand π-π interactions, and thus form a 3D structure.

In addition, the paper also acid-based ionic liquids for the literature research, and proposed a possible future direction of development.
