The crystal structures of two brominated derivatives of 4-amino-N-butyl-1,8-naphthalenedicarboximide [alternative systematic names: 8-bromo-2-butyl-7-butylamino-1H-benzo[de]isoquinoline-1,3(2H)-dione, C20H23BrN2O2, and 7-amino-8-bromo-2-butyl-1H-benzo[de]isoquinoline-1,3(2H)-dione, C16H15BrN2O2] are reported. The N-butyl groups, which are common to both compounds, are perpendicular to the plane of the naphthalenedicarboximide ring system. The butylamino group at position 4 in (1) is in the plane of the naphthalenedicarboximide ring, with the butyl group oriented towards the peri position of the naphthalenedicarboximide ring. This arrangement results in an opening of the (ring C)-N-(butyl C) angle.
报道了4-氨基-N-丁基-1,8-萘二甲酰亚胺的两种溴化衍生物的晶体结构[替代系统名称：8-溴-2-丁基-7-丁基氨基-1H-苯并[de]异喹啉-1,3(2H)-二酮，C20H23BrN2O2，以及7-氨基-8-溴-2-丁基-1H-苯并[de]异喹啉-1,3(2H)-二酮，C16H15BrN2O2]。这两种化合物共有的N-丁基基团垂直于萘二甲酰亚胺环系统的平面。(1)中4位的丁基氨基位于萘二甲酰亚胺环的平面内，丁基朝向萘二甲酰亚胺环的邻位。这种排列导致(环C)-N-(丁基C)角张开。
