摘要

A novel Cu(I)-cluster based coordination compound formulated as {(Cu2I2)(2)[Cu-6(dmpymt)(6)]}(n) (Hdmpymt = 4,6-dimethylpyrimidine-2-thione) was synthesized under solvo-thermal condition and characterized by single-crystal X ray diffraction, elemental analysis, IR spectroscopy, thermal analysis, and powder X-ray diffraction. Compound 1 is an infinite 3D structure composed of Cu2I2 and Cu6S6 binary Cu(I) clusters with 6(6) topology, and displays high thermal stability and good solvent stability. Fluorescence experiments illustrate that compound 1 displays apparently red luminescence emission and selectively turn-off fluorescence response for CrO42- and Cr2O72- in water, showing potential luminescent probes for detecting Cr(VI) ions.
