Abstract: The structure of strontium magnesium diphosphate, SrMgP₂O₇, belongs to the -Ca₂P₂O₇ isotypical pyrophosphates series SrMP₂O₇ (M = Cr, Mn, Fe, Co, Ni, Cu, Zn). Mg^II atoms occupy square-pyramidal coordination and are isolated in the structure. [MgO₅] units and the [P₂O₇] groups form a three-dimensional framework with channels along [100] and [010], in which are located Sr²⁺ ions.
