1-Methyl-3-phenylimidazolidine-2-thione
The asymmetric unit of the title cyclic thio-urea derivative, C10H12N2S, comprises two mol-ecules, each of which has a twist about the CH2-CH2 bond within the five-membered ring. The major difference between the independent mol-ecules is manifested in the relative orientations of the five- and six-membered rings [dihedral angles between the least-squares planes = 28.03 (11) and 41.54 (11)°]. A ...
متن کامل1-Methyl-1H-benzimidazole-2(3H)-thione
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.

The title compound, C(18)H(18)N(4)OS, has an almost planar 1,2,4-triazole ring [r.m.s. deviation = 0.0036 (2) Å], which makes dihedral angles of 78.5 (2) and 77.6 (11)° with the two phenyl rings. An intra-molecular N-H⋯S inter-action occurs. In the crystal, mol-ecules are linked by an inter-molecular three-centre N-H⋯(O,S) cyclic hydrogen-bonding inter-action.
متن کامل3-Methyl-5-methylsulfanyl-1,3,4-thiadiazole-2(3H)-thione
The title compound, C(4)H(6)N(2)S(3), has two very similar mol-ecules per asymmetric unit. The nine non-H atoms in each mol-ecule are coplanar, both having comparable r.m.s. deviations of 0.002 Å. The main inter-est in the rather simple structure resides in a survey of very weak (in some cases, borderline) non-bonding inter-actions of various kinds, viz. S⋯S, C-H⋯π, π-π [centroid-centroid dista...
متن کامل3-(1-Phenylethyl)-1,3-thiazinane-2-thione
In the title mol-ecule, C(12)H(15)NS(2), the 1,3-thia-zinane ring has a half-boat conformation; the C atom at position 5 deviates by 0.715 (2) Å from the mean plane (P) of the remaining five atoms. Plane P and the phenyl ring form a dihedral angle of 83.62 (3)°. In the crystal structure, weak inter-molecular C-H⋯S hydrogen bonds link mol-ecules related by translation along the axis a into chains.
