organic compounds
In the crystal structure of the title compound, C5H6N+·C6H3N2O4−, the 5-carboxypyrazine-2-carboxylate (pdc) monoanion lies entirely on a mirror plane. The N and C atoms of the cation, together with their attached H atoms, lie on the same mirror plane. A supramolecular network is assembled between the pdc anions and pyridinium cations via N—H
O, O—HO and C—HO hydrogen bonding.
O, O—HO and C—HO hydrogen bonding.
research communications
The crystal structure of the dioxygenase FrbJ is reported. An access tunnel was found at the back of the active site, which connects the putative binding site for α-ketoglutarate to the solvent.
organic compounds
In the crystal structure of the title compound, C11H14N3O2+·I−, intermolecular C—HO and C—HI hydrogen bonds link the ions into a three-dimensional structure. The imidazolinium ring is planar within 0.0502 (2) Å. The dihedral angle of the imidazolinium plane and the benzene ring plane is 78.45 (7)°.

The title compound, C12H17N2O+·I-, is a new example of a tetrahydrofolate (THF) co-enzyme model. The N-C-N moiety of the imidazoline ring shows C-N bond lengths of 1.306 (4) and 1.326 (4) Å, suggesting that the positive charge is delocalized.
organic compounds
In the crystal structure of the title compound, C14H17NO3, intermolecular O—HO hydrogen bonds [OO = 2.692 (4) Å] link the molecules into extended one-dimensional chains. These chains are, in turn, linked into a three-dimensional network by weak intermolecular C—HO interactions [CO = 3.368 (5) Å].
O hydrogen bonds [OO = 2.692 (4) Å] link the molecules into extended one-dimensional chains. These chains are, in turn, linked into a three-dimensional network by weak intermolecular C—HO interactions [CO = 3.368 (5) Å].
