【 摘 要 】

In the title compound, C11H12N2O2·C4H4O4·H2O, the l-tryp­to­phan mol­ecule crystallized as a zwitterion, together with a neutral fumaric acid mol­ecule and a water solvent mol­ecule. In the crystal, the three components are linked by a series of N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds, forming slabs lying parallel to (001). The slabs are connected by O—H⋯O hydrogen bonds, involving inversion-related fumaric acid groups, leading to the formation of a three-dimensional structure.
