A dual fluorescent/phosphorescent solid was produced using the triazole-assisted synthesis method under hydro(solvo)thermal conditions. The title compound emitted blue luminescence that turned green when UV irradiation was stopped. It also exhibited stable PL properties with good thermal and photostability. Furthermore, the 3D inorganic skeleton in NTOU-6 underwent structural transformation into another inorganic metallophosphite solid ( NTOU-6b ) and water adsorption was observed during this process of structural reconstruction. The detailed structural features of both compounds were also determined by single-crystal X-ray diffraction. This is a very rare example of a metallophosphite with the interesting properties of luminescence color switching (blue to green), water adsorption, and structural transformation. The synthesis, structural diversity, adsorption, material stability, and luminescence properties were also discussed. This is a very rare example of a crystalline metallophosphite/phosphate framework with structural transformation, water adsorption, and luminescence color switching (blue to green).
