Hydronium (3-oxo-1-phosphono-1,3-dihydroisobenzofuran-1-yl)phosphonate

چکیده
In the title compound, H(3)O(+)·C(8)H(7)O(8)P(2) (-), the anions form inversion dimmers by way of pairs of O-H⋯O hydrogen bonds involving the phospho-nic functions and via the hydro-nium cation. Further O-H⋯O links involving the hydronium cation play a prominant part in the cohesion of the crystal structure by building bridges between bis-phospho-nate 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 hydrogen-bond network. The benzene ring and the C=O atoms of the furan ring are disordered over two sets of positions of equal occupancy.

In the title mol-ecule, C(18)H(20)NO(3)PS, the benzene ring and the benzothia-zole mean plane are almost coplanar, forming a dihedral angle of 2.29 (2)°. The two ethyl groups are each disordered over two conformations in ratios that refined to 0.59 (1):0.41 (1) and 0.56 (1):0.44 (1). In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into layers parallel to the bc plane.
