Abstract: A new mebendazolium di­hydrogen phosphate phospho­ric acid solid material was obtained and characterized by single-crystal X-ray diffraction and complementary solid-state techniques {systematic name: 5-benzoyl-2-[(meth­oxy­carbon­yl)amino]-1H-1,3-benzo­diazol-3-ium di­hydrogen phosphate-phos­pho­ric acid (1/1), C16H14N3O3+·H2PO4-·H3PO4}. Structure solution confirmed proton transfer from phospho­ric acid towards the basic imidazole ring of mebendazole. The mebendazolium cation and the di­hydrogen phosphate anion assemble in the solid state in a cyclic hydrogen-bond-driven supra­molecular motif, as observed in all mebendazolium/oxyanions structures reported in the literature. This salt crystallizes in the monoclinic P21/c (No. 14) space group. A detailed study of the crystal structure performed by atom-to-atom and global Hirshfeld surface analysis indicates that several hydrogen bonds act as the main inter­molecular inter­actions stabillizing the material. The new material is stable up to 458 K.
