Bis(4-methoxybenzylammonium) dihydrogen diphosphate

Abstract

In the title compound, 2C8H12NO+·H 2P2O7 2-, the linked PO4 groups of the diphosphate anion are almost eclipsed and the P - O - P angle is 134.45 (7)°. In the crystal, infinite ribbons of H2P2O7 2- anions propagate in [100], being linked by strong O - H⋯O hydrogen bonds. The 4-methoxybenzylammonium cations bond to the diphosphate chains by N - H⋯O and C - H⋯O links, and are themselves linked by C - H⋯π interactions.
