XRD, thermal, FTIR and SEM studies on gel grown γ-glycine crystals

TLDR: In this article, α-and γ-forms of Glycine were crystallized in silica gel by reduction of solubility method and characterized by single crystal X-ray diffraction studies and density determination.

Abstract: Glycine is the smallest among amino acids. The polymorphs, α- and γ-forms of glycine were crystallized in silica gel by reduction of solubility method. The grown crystals were characterized by single crystal X-ray diffraction studies and density determination. Fourier transform infrared spectroscopic studies and thermogravimetric analysis of γ-glycine were also conducted. Morphological and scanning electron microscopic (SEM) studies were also made and compared with the crystal packing. (© 2007 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)
