Phthalazin-1(2H)-one–picric acid (1/1)

The geometric parameters of the title compound, C(8)H(6)N(2)O·C(6)H(3)N(3)O(7), are in the usual ranges. The three nitro groups are almost coplanar with the aromatic picrate ring [dihedral angles 10.2 (2)°, 7.62 (16) and 8.08 (17)°]. The mol­ecular conformation of the picric acid is stabilized by an...

description The geometric parameters of the title compound, C(8)H(6)N(2)O·C(6)H(3)N(3)O(7), are in the usual ranges. The three nitro groups are almost coplanar with the aromatic picrate ring [dihedral angles 10.2 (2)°, 7.62 (16) and 8.08 (17)°]. The mol­ecular conformation of the picric acid is stabilized by an intra­molecular O—H⋯O hydrogen bond. The phthalazin-1(2H)-one mol­ecules are connected via N—H⋯O hydrogen bonds, forming centrosymmetric dimers.
