ABSTRACT
In the title compound, C(12)H(11)N(2) (+)·I(-), the aromatic rings are oriented at a dihedral angle of 73.40â (3)°. In the crystal structure, π-π contacts between the pyridine rings and the benzene and pyridine rings [centroid-centroid distances = 3.548â (3) and 4.211â (3)â Å] may stabilize the structure.
ABSTRACT
The asymmetric unit of the title compound, C(15)H(24)O(4), contains one half-mol-ecule; a twofold rotation axis passes through the central C atom. The non-planar six- and five-membered rings adopt chair and envelope conformations, respectively. In the crystal structure, inter-molecular C-Hâ¯O hydrogen bonds link the mol-ecules.
ABSTRACT
The title compound, C(12)H(13)NO(3), was prepared by the nucleophilic substitution reaction of acryloyl chloride with glycylglycine. In the crystal structure, inter-molecular N-Hâ¯O, O-Hâ¯O and C-Hâ¯O hydrogen bonds link the mol-ecules into a three-dimensional network.
