Hydronium (3-oxo-1-phosphono-1,3-dihydroisobenzofuran-1-yl)phosphonate
Résumé
In the title compound, H3O+center dot C8H7O8P2-, the anions form inversion dimmers by way of pairs of O-H center dot center dot center dot O hydrogen bonds involving the phosphonic functions and via the hydronium cation. Further O-H center dot center dot center dot O links involving the hydronium cation play a prominant part in the cohesion of the crystal structure by building bridges between bisphosphonate pairs, forming infinite ribbons along the b-axis direction and by cross-linking these ribbons perpendicularly along the a-axis direction, forming an infinite three-dimensional hydrogenbond network. The benzene ring and the C=O atoms of the furan ring are disordered over two sets of positions of equal occupancy.
