(2R,5S)-5-Benzyl-2,3-dimethyl-4-oxo-2-phenylimidazolidin-1-ium chloride
The title hydro-chloride salt, C(18)H(21)N(2)O(+)·Cl(-), is an imidazolidinone catalyst, which was derived from L-phenyl-alanine through cyclization with acetophenone. The imidazolidinone compound has a five-membered heterocyclic ring including two chiral centres. The imidazolidinone ring displays an envelope conformation, with the flap protonated N atom lying 0.497 (3) Å above the mean plane o...

In the crystal structure of the title compound, C(4)H(7)N(4)O(+)·Cl(-)·2H(2)O, adjacent cations are connected to one another through N-H⋯O hydrogen bonds, forming infinite chains along the b axis. These chains are further hydrogen bonded to the chloride anions and water mol-ecules, resulting in a three-dimensional network. The pyrimidine rings of adjacent mol-ecules are arranged in an anti-para...

The hydrazinium residue in the cation of the title salt, C(6)H(10)N(3)O(2)S(+)·Cl(-), is twisted out of the plane of the benzene ring to which it is attached [N-N-C-C torsion angle = 25.9 (2)°] and the amino group is almost perpendicular to the benzene ring [N-S-C-C torsion angle = 88.71 (16)°]. In the crystal, the cations are linked by N-H⋯O hydrogen bonds and π-π inter-actions [ring centroid ...
