In the title naphthalimide derivative, C(23)H(26)N(2)O(6), 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, inter-molecular O-H⋯O and C-H⋯O hydrogen bonds link neighbouring mol-ecules, forming R(2) (2)(9) hydrogen-bond ring motifs. These rings are further inter-connected by inter-molecular N-H⋯O and C-H⋯O hydrogen bonds into a three-dimensional supra-molecular network.
在标题萘二甲酰亚胺衍生物C(23)H(26)N(2)O(6)中，1,8 - 萘二甲酰亚胺体系基本呈平面状[最大偏差 = 0.0456 (16) Å]。在1,8 - 萘二甲酰亚胺单元中观察到交替出现的长、短C - C键长的特征模式。穿过氨基甲酸甲酯和乙酸基团的平均平面与1,8 - 萘二甲酰亚胺平面分别形成42.30 (9)°和61.59 (9)°的二面角。在晶体结构中，分子间的O - H⋯O和C - H⋯O氢键连接相邻分子，形成R(2) (2)(9)氢键环基序。这些环通过分子间的N - H⋯O和C - H⋯O氢键进一步相互连接成三维超分子网络。
