A novel three-dimensional metal-organic framework (MOF), [H3O][Cd3Cl(PZC)(3)(H2O)(3)] (1), has been synthesized based on a trinuclear Cd(II) cluster and H(2)PZC ligand (H(2)PZC = 1H-pyrazole-4-carboxylic acid). Compound 1 crystallizes in a trigonal crystal system with the space group R3m. Trinuclear Cd(II)-clusters as secondary building units (SBU) are further connected by the H(2)PZC ligand to form a two-fold interpenetrated 3D framework. Compound 1 exhibits excellent water-stability and good luminescence properties for various organic solvents and different metal ions. The systematic investigation for luminescence indicates that compound 1 possesses unique performance for the detection of acetone, Fe2+ and Na+ based on a fluorescence quenching and enhancing mechanism, thus it can be regarded as a potential luminescence probe for the detection of acetone, Fe2+ and Na+.
