A new protonated borophosphate (H 3 O)Mg(H 2 O) 2 [BP 2 O 8 ]·H 2 O ( 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 P 6(1)22 (No 178), a = 9.4462(7) Å, c = 15.759(2) Å, V = 1217.8(2) Å 3 , and Z = 6. There exist infinite helical $^1_\infty$ {[BP 2 O 8 ] 3– } ribbons built up from corner‐sharing PO 4 and BO 4 tetrahedra, which are connected by MgO 4 (H 2 O) 2 leading to an infinite three‐dimensional open‐framework. The H 3 O + 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.
