Crystal structure and hydrogen-bonding patterns in 5-fluorocytosinium picrate
In the crystal structure of the title compound, 5-fluoro-cytosinium picrate, C4H5FN3O+·C6H2N3O7-, one N heteroatom of the 5-fluoro-cytosine (5FC) ring is protonated. The 5FC ring forms a dihedral angle of 19.97 (11)° with the ring of the picrate (PA-) anion. In the crystal, the 5FC+ cation inter-acts with the PA- anion through three-centre N-H⋯O hydrogen bonds, forming two conjoined rings havin...
متن کاملHydrogen bond mediated stabilization of the salt bridge structure for the glycine dimer anion.
The formation of a salt bridge in deprotonated glycine dimer anions in a solvent-free environment is investigated using both infrared multiple photon dissociation spectroscopy between 600 and 1800 cm(-1) and theory. The zwitterionic and nonzwitterionic forms of glycine in this complex are computed to be nearly iso-energetic, yet predominantly the zwitterionic form is observed experimentally. Th...
متن کاملA double Rydberg anion with a hydrogen bond and a solvated double Rydberg anion: Interpretation of the photoelectron
A double Rydberg anion has two electrons in diffuse orbitals that are bound by a closed-shell, cationic core. Low-energy features in the recently reported photoelectron spectrum of N2H7 2 are assigned to double Rydberg anions on the basis of electron propagator calculations employing Brueckner doubles, coupled-cluster reference states. The lowest electron detachment energy, 0.415 eV, correspond...
متن کاملUnderstanding hydrogen-bond patterns in proteins using network motifs
UNLABELLED Protein structures can be viewed as networks of contacts (edges) between amino-acid residues (nodes). Here we dissect proteins into sub-graphs consisting of six nodes and their corresponding edges, with an edge being either a backbone hydrogen bond (H-bond) or a covalent interaction. Six thousand three hundred and twenty-two such sub-graphs were found in a large non-redundant dataset...
متن کاملGraph-set analysis of hydrogen-bond patterns: some mathematical concepts.
To provide a foundation for further theoretical and software development of the application of graph sets to patterns of hydrogen bonding and other intermolecular interactions a number of mathematical concepts and tools are defined, developed and demonstrated. Following a review of the basic definitions and uses of graph sets, the directional properties of hydrogen bonds are now included in the...
