1,3-Dibenzylimidazolidine-2-thione
In the title compound, C(17)H(18)N(2)S, the imidazolidine ring adopts a twisted conformation. In the crystal, mol-ecules are linked by slipped π-π inter-actions between the benzene rings of neighbouring mol-ecules [centroid-to-centroid distance = 3.903 (2) Å].
متن کاملPerhydrobenzimidazole-2-thione
The studied crystal of the title compound, C(7)H(12)N(2)S, is a racemic mixture of two isomers, viz. S,S and R,R. The two isomers share the same position on a mirror plane in the space group P2(1)/m; thus all atoms except one are disordered between two positions in a 1:1 ratio. Inter-molecular N-H⋯S hydrogen bonds link the mol-ecules into chains propagating in the [010] direction.
متن کامل1H-Benzimidazole-2(3H)-thione
The asymmetric unit of the title compound, C(7)H(6)N(2)S, contains one half-mol-ecule; the C and S atoms of the C=S group lie on a crystallographic mirror plane. In the crystal structure, inter-molecular N-H⋯S hydrogen bonds link the mol-ecules.

The title compound crystallizes as a chloro-form solvate, C(20)H(23)N(3)O(3)S·CHCl(3), with two crystallographically independent units. The independent units have distinctly different inter-action patterns between the aza-crown macrocycle and the chloro-form solvent mol-ecule. In one of them, the chloro-form mol-ecule forms C-H⋯N and Cl⋯H-C hydrogen bonds with the aza-crown macrocycle (as a pro...
متن کاملGold Thione Complexes
The reaction of the ligand Et4todit (4,5,6,7-Tetrathiocino-[1,2-b:3,4-b']diimidazolyl-1,3,8,10-tetraethyl-2,9-dithione) with gold complexes leads to the dinuclear gold(I) complexes [{Au(C6F5)}2(Et4todit)] and [Au(Et4todit)]2(OTf)2, which do not contain any gold-gold interactions, or to the gold(III) derivative [{Au(C6F5)3}2(Et4todit)]. The crystal structures have been established by X-ray diffr...
