A new inorganic–organic hybrid material (C 10 H 8 N 2 H) 2 (Mo 8 O 26 ) · 2NH 4 ( 1 ) was prepared under solvothermal conditions (H 2 O/ethanol), which was then used as a starting material in the synthesis of another material, (C 10 H 8 N 2 Cu) 2 (Mo 8 O 26 ) · 2NH 4 ( 2 ). Each compound has been characterized by single-crystal X-ray diffraction, X-ray powder diffraction, elemental analysis, thermogravimetric analysis, fluorescence, FT-IR, and bond valence sum calculations. The comparative study focuses on the transformation and structural change between 1 and 2 , which arises from the simple substitution of the proton in 1 with the Cu + ions. The other surprising feature is that Cu + ions can not only directly be used to substitute the proton of 1 but also ameliorate its photoluminescence property. It means that 1 appears to have recognizable functional protons in the solid-state structure and, hence, can very well be considered as an ideal precursor agent to design the functional materials with special architectures and photoactive properties.
