Bis(4-meth­oxy­benzyl­ammonium) dihydrogen diphosphate

A. Elboulali, S. Akriche, S. S. Al-Deyab and M. Rzaigui

Abstract: In the title compound, 2C8H12NO+·H2P2O72-, 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 H2P2O72- 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...[pi] inter­actions.
