L-tryptophan L-tryptophanium chloride is a new salt with (A⋯A(+)) type dimeric cation. It crystallizes in the monoclinic system (space group P2(1), Z=2). The asymmetric unit contains one zwitterionic L-tryptophan molecule, one L-tryptophanium cation and one chloride anion. The dimeric cation is formed by a O-H⋯O hydrogen bond with the O⋯O distance equal to 2.5556(18) Å. The infrared and Raman spectra of the crystal are studied and compared with the spectra of L-tryptophanium chloride.
L-色氨酸氯化L-色氨酸鎓是一种具有(A⋯A(+))型二聚阳离子的新盐。它在单斜晶系中结晶（空间群P2(1)，Z=2）。不对称单元包含一个两性离子L-色氨酸分子、一个L-色氨酸鎓阳离子和一个氯离子阴离子。二聚阳离子通过O-H⋯O氢键形成，O⋯O距离等于2.5556(18) Å。研究了该晶体的红外光谱和拉曼光谱，并与氯化L-色氨酸鎓的光谱进行了比较。
