Hydrothermal Synthesis, Crystal Structure, and Luminescent Properties of One New Inorganic-organic Hybrid Compound (ClBzQl)₃[PMo₁₂O₄₀] (ClBzQl = 1- (4′-Cl-benzyl)quinolinium cation)

Abstract

A new polyoxometalate-based inorganic-organic hybrid compound (ClBzQl)₃[PMo₁₂O₄₀] 1 (ClBzQl = 1-(4′-Cl-benzyl)quinoli- nium cation) has been synthesized by hydrothermal method and characterized by IR, elemental analysis, and X-ray crystallography. Analysis of the crystal structure of 1 suggests that there are multiform intermolecular C−H···O hydrogen bonds between polyoxoanions and organic cations and obvious face-to-face π−π interactions involving quinoline rings of adjacent cations. The luminescent properties of the compound 1 in the solid state at room temperature were investigated.
