The rings of the three-ring cytisine system in the title compound [systematic name: (1R,5S)-1,2,3,4,5,6-hexa-hydro-1,5-methano-8H-pyrido[1,2-a][1,5]diazo-cine-8-thione], C(12)H(16)N(2)S, have planar [maximum deviation 0.0170 (7) Å], half-chair and chair conformations. In the crystal structure, relatively short and directional C-H⋯π inter-actions and weaker secondary C-H⋯S contacts join the mol-...

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 translation along the b axis into chains.

In the title compound, C(25)H(21)F(2)N(3)O(3)S, the morpholine ring adopts a chair conformation. The 1,3,4-oxadiazole-2(3H)-thione group makes dihedral angles of 78.69 (8), 53.56 (7) and 55.30 (9)° with the benzene rings. In the crystal, O-H⋯O, C-H⋯S and C-H⋯F hydrogen bonds linked the mol-ecules into layers lying parallel to the ab plane. Weak C-H⋯π inter-actions also occur.

The title mol-ecule, C(16)H(15)ClN(2)OS, exists in the solid state in its thione form with typical thio-urea C-S and C-O bonds lengths, as well as shortened C-N bonds. An intra-molecular N-H⋯O hydrogen bond stabilizes the mol-ecular conformation and inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers. The dihedral angle between the aromatic rings is 50.18 (5)°.

The title thio-uracil derivative, C(9)H(11)N(3)OS, exists in the thione form. The six atoms comprising the ring are almost coplanar [r.m.s. deviation = 0.015 Å] and the 2-methyl-propyl group lies approximately perpendicular to this plane [the N-C-C-C torsion angle is 72.88 (14)°]. Linear supra-molecular chains along [001] sustained by N-H⋯O and N-H⋯S hydrogen bonding feature in the crystal pack...

The title compound, C(8)H(8)N(2)S, was prepared by the condensation of N-methyl-1,2-phenyl-enediamine and carbon disulfide. The crystal structure is stabilized by a C-H⋯π inter-action between a benzene H atom and the benzene ring of a neighbouring mol-ecule, and by inter-molecular N-H⋯S inter-actions.

In the title mol-ecule, C(13)H(13)ClN(2)OS, the heterocyclic ring adopts a flattened boat conformation, and the plane through the four coplanar atoms makes a dihedral angle of 87.92 (10)° with the benzene ring. The thione, acetyl and methyl groups have equatorial orientations with respect to the attached heterocyclic ring. The chloro-phenyl group has an axial orientation. Inter-molecular N-H⋯O,...

The title compound, C(16)H(24)N(2)OS, is twisted about the central N(H)-C bond with the C-N-C-S torsion angle being 119.6 (3)°. The carbonyl O and thione S atoms are directed to opposite sides of the mol-ecule, a conformation that allows for the formation of a linear supra-molecular chain comprising alternating eight-membered {⋯HNCS}(2) and 14-membered {⋯HCNCNCO}(2) synthons.

The five-membered ring of the title compound Δ(1)-1,2,4-triazoline-5-thione, C(11)H(13)N(3)S, is almost planar (r.m.s. deviation = 0.009 Å); the phenyl ring is aligned at 84.6 (2)° with respect to the five-membered ring. The crystal studied was a racemic twin with an approximate 20% minor twin component. Weak inter-molecular C-H⋯N hydrogen bonding is present in the crystal structure.
