Orthorhombic modification of (E)-4-benzylidene-2-phenyl-1,3-oxazol-5(4H)-one: whole molecule disorder
نویسنده
چکیده
The title mol-ecule, C(16)H(11)NO(2), is disordered about a pseudo-twofold rotation axis that approximately bis-ects the mol-ecule along the C=O double bond. The two overlapping components are planar [r.m.s. deviation = 0.10 Å in the major 0.537 (4) component and 0.07 Å in the minor component]. The two components are aligned at 1.8 (3)°.

The title compound, C(19)H(17)NO(5), was synthesized as part of a continuing project involving the structures of oxazolone derivatives. The mol-ecule adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is slightly twisted out of the plane of the oxazolone ring system by 11.2 (2)°. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

The title mol-ecule, C(17)H(13)NO(3), adopts a Z configuration about the central olefinic bond. The 2-phenyl ring is almost coplanar with the plane of the oxazolone ring system, making a dihedral angle of 2.03 (11)°. The crystal structure is stabilized by π-π inter-actions between the oxazolone ring and phenyl ring of a neighbouring mol-ecule [centroid-centroid distance = 3.550 (3)Å], and by tw...

The central aza-lactone ring in the title compound, C(18)H(15)NO(4), is planar (r.m.s. deviation 0.05, 0.12 Å) in both independent mol-ecules comprising the asymmetric unit. The benzyl-idene substituent is coplanar with this ring [dihedral angle between the planes = 1.8 (1)° in the first mol-ecule and 2.8 (1)° in the second], as is the phenyl substitutent [dihedral angle between rings = 4.6 (1)...

In the title compound, C(17)H(14)N(2)O(3), the oxazolone ring is essentially planar [maximum deviation = 0.004 (1) Å] and is oriented with respect to the phenyl and benzene rings at 10.06 (9) and 5.63 (8)°, respectively; the dihedral angle between the phenyl ring and the benzene ring is 15.69 (8)°. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into chains running along the a axis. Ne...
