Abstract
The title compound, C22H29N3O2Si·0.5CHCl3, crystallizes in the the triclinic space group P\overline{1} with two host molecules and one chloroform molecule in the asymmetric unit. The core of the molecule consists of a urea unit bound to a 3-amino-acryloyl group. These units are almost planar in both molecules [average deviation from plane of 0.05 (6) Å in molecule A and 0.04 (5) Å in molecule B]. The main difference between molecules A and B involves the dihedral angles of the phenyl groups. One phenyl ring makes dihedral angles of 71.14 (6)° (molecule A) and 82.81 (7)° (molecule B) with respect to the core (C4N3O2) of the molecule [14.56 (9)° (molecule A) and 5.7 (1)° (molecule B) for the other phenyl ring]. Another prominent feature is the intramolecular N—H...O hydrogen bond present in both crystallographically independent molecules.
