(E)-N-Phenyl-N-(phenyl­carbamo­yl)-3-[prop­yl(tri­methyl­sil­yl)amino]­acryl­amide chloro­form hemisolvate

The title compound, C(22)H(29)N(3)O(2)Si·0.5CHCl(3), crystallizes in the the triclinic space group P [Image: see text] 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 (C(4)N(3)O(2)) 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. [Image: see text]
