摘要：
L-Tryptophan L-tryptophanium chloride is a new salt with (A center dot center dot center dot 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 center dot center dot center dot O hydrogen bond with the O center dot center dot center dot O distance equal to 2.5556(18) angstrom. The infrared and Raman spectra of the crystal are studied and compared with the spectra of L-tryptophanium chloride. (C) 2014 Elsevier B.V. All rights reserved.
