Crystal and molecular structure of monoglycine nitrate

Study of the Family of Glycine–Selenious Acid Addition Compounds: Crystal Structure of Diglycine Hydrogen Selenite and Vibrational Spectra and DSC Measurement of Diglycine Hydrogen Selenite and Monoglycine–Selenious Acid Crystals

“…Only linear (two-center) hydrogen bonds were found for the NH> group in the crystal structure of DGSe(IV), similar to MGSe(IV) (4). In contrast to some related compounds of glycine (6)(7)(8), no bifurcated (three-center) hydrogen bond was found.…”

catena-Poly[[[tetraaquamagnesium(II)]-μ-glycine-κ2O:O′] dinitrate]

“…This is the most common case for such salts, although glycinium or glycinate compounds can also occur, e.g. copper glycinate nitrate monohydrate (Davies et al, 1992) or glycinium nitrate (Narayanan & Venkataraman, 1975). In (I), the glycine molecules are slightly twisted from a planar conformation, the O2-C1-C2-N3 torsion angle being 179.56 (1) .…”

The Behavior of the Deformation Vibration of NH3 in Semi-Organic Crystals under High Pressure Studied by Raman Spectroscopy

“…Because H-bonds are long-range interactions, a group N-H is bonded to more than one acceptor (oxygen atom) at the same time and two of the hydrogen atoms of the NH3 group form bifurcated hydrogen bonds (BH-bond). The third hydrogen atom of the NH3 + group forms a strong intermolecular conventional hydrogen bond (H-bond) with lengths 2.792 Å and angle 169° [12]. An analysis and comparison of the H-bonds in both compounds reveals substantial differences.…”
