3-Amino-5-methyl-5-(4-pyridyl)hydantoin
The title compound, 3-amino-5-methyl-5-(4-pyrid-yl)imid-azol-idine-2,4-dione, C(9)H(10)N(4)O(2), was obtained by reaction of 5-methyl-5-(4-pyrid-yl)hydantoin with hydrazine. It crystallizes as a racemate in the tetra-gonal space group I4(1)/a with one mol-ecule in the asymmetric unit. The dihedral angle between the pyridine ring and the five-membered hydantoin ring is 47.99 (3)° In the crystal ...

In the title salt, C(6)H(9)N(2) (+)·C(5)H(7)O(4) (-), the 2-amino-5-methyl-pyridinium cation is essentially planar, with a maximum deviation of 0.008 (1) Å. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxyl-ate O atoms via a pair of N-H⋯O hydrogen bonds, forming an R(2) (2)(8) ring motif. The 4-carb-oxy-butano-ate anions are linked via O-H⋯O hydroge...

In the title salt, C(5)H(6)ClN(2) (+)·C(7)H(5)O(3) (-), the carboxyl-ate mean plane of the 4-hydroxy-benzoate anion is twisted by 7.16 (9)° from the attached ring. In the crystal structure, the cations and anions are linked via O-H⋯O and N-H⋯O hydrogen bonds, as well as C-H⋯O contacts, forming a three-dimensional network. In addition, weak π-π inter-actions involving the benzene and pyridinium ...
