In the title 1:1 adduct, C(6)H(6)N(2)O·C(11)H(8)O(2), the amide group is slightly twisted out of the plane of the aromatic ring, with a C-C-C-N torsion angle of 25.11 (19)°, whereas the carb-oxy-lic acid group is approximately coplanar with the bicylic ring system, with a C-C-C-O torsion angle of 10.9 (2)°. The amide groups from two isonicotinamide(More)
The asymmetric unit of the racemic title compound, C(10)H(16)N(2)S(2), a C(2)-symmetric bis-(thiol-actam), contains one half-mol-ecule, the complete mol-ecule being generated by a twofold axis symmetry operation. The five-membered ring is nearly planar, with a maximum deviation of 0.025 (1) Å. In the crystal, the mol-ecules are linked via weak C-H⋯S(More)
The title compound, C(14)H(16)N(2)O(3), is an NH-vinyl-ogous amide (enaminone) produced by the reaction of 4-nitro-phenacyl bromide with azepane-2-thione. The conformation about the C=C bond [1.3927 (14) Å] is Z, which allows for the formation of an intra-molecular N-H⋯O hydrogen bond that leads to an S(6) loop. Inversion-related mol-ecules associate via(More)
The title compound, C21H21NO, is a vinyl-ogous amide (enaminone) produced by reaction of 1-(2-phenyl-prop-2-en-1-yl)pyrrolidine-2-thione with phenacyl bromide. In the mol-ecule, the phenyl rings are twisted from the mean plane of the pyrrolidine ring by 11.2 (1) and 67.3 (1)°. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules related by(More)
The asymmetric unit of the title compound, C12H10N2, which may serve as a model for mitosenes, contains two independent mol-ecules. The conformation of the five-membered rings in both molecules is envelope, with the central CH2-CH2-CH2 C atom at the flap in each case. In the crystal, they inter-act by a combination of weak C-H⋯N and π-π inter-actions(More)
