Abstract: | A new protonated borophosphate (H3O)Mg(H2O)2BP2O8]·H2O ( 1 ) was synthesized under mild hydrothermal conditions and characterized by single‐crystal X‐ray diffraction, FTIR spectroscopy and TG‐DTA. The compound crystallizes in the hexagonal system, space group P6(1)22 (No 178), a = 9.4462(7) Å, c = 15.759(2) Å, V = 1217.8(2) Å3, and Z = 6. There exist infinite helical $^1_\infty$ {BP2O8]3–} ribbons built up from corner‐sharing PO4 and BO4 tetrahedra, which are connected by MgO4(H2O)2 leading to an infinite three‐dimensional open‐framework. The H3O+ ions are located at the free thread of the helical ribbons, whereas crystallized water occupy the channels of the helical ribbons. The dehydration of the compound occurs at a higher temperature which is presumably due to the anisotropic hydrogen bonds in the crystal structure. The luminescent properties of the compound were studied. |
