Abstract
In the title naphthalimide derivative, C23H26N2O6, the 1,8-naphthalimide system is essentially planar [maximum deviation = 0.0456 (16) Å]. A characteristic pattern of alternating long and short C—C bond lengths is observed in the 1,8-naphthalimide unit. The mean planes through the methyl carbamate and acetic acid groups form dihedral angles of 42.30 (9) and 61.59 (9)°, respectively, with the 1,8-naphthalimide plane. In the crystal structure, intermolecular O—H⋯O and C—H⋯O hydrogen bonds link neighbouring molecules, forming R 2 2(9) hydrogen-bond ring motifs. These rings are further interconnected by intermolecular N—H⋯O and C—H⋯O hydrogen bonds into a three-dimensional supramolecular network.
