摘要：
In this paper, 1,3-bis(carboxymethyl)imidazolium nitrate was prepared, and its structure was also determined by a single-crystal X-ray diffraction. Its FT-infrared and Raman spectra were measured and reported. The crystal structure and the type of O-H center dot center dot center dot O hydrogen bonds were analyzed on the basis of the vibrational spectroscopy and Density Functional Theory (DFF) calculation. Additionally, thermal stability of 1,3-bis(carboxymethyl)imidazolium nitrate and its decomposition process were discussed. (C) 2017 Elsevier B.V. All rights reserved.
