Isoquinoline 1-oxide-2-nitrobenzoic acid (1/1)

R. Moreno-Fuquen, A. M. Montaño and R. Atencio

Abstract: The title molecular complex, C₉H₇NO·C₇H₅NO₄, owes its formation to an intermolecular hydrogen bond between the O-H and N-O groups, with an OO distance of 2.514 (2) Å. The dihedral angle between the planes of the isoquinoline N-oxide and nitrobenzoic acid rings of the complex is 49.91 (4)°. The crystal structure exhibits overlap between the aromatic rings of the molecules in the [101] direction.
