The complete molecule of the title compound, C(19)H(22)N(2)S, is generated by crystallographic twofold symmetry with the C=S group lying on the rotation axis. The imidazolidine ring adopts a flattened twist conformation. The dihedral angle between the asymmetric part of the imidazolidine-2-thione fragment and the benzene ring is 89.49 (17)°.

In the title compound, C(5)H(2)S(4), the terminal monocyclic S atom deviates by 0.117 (1) Å from the mean plane of the other non-H atoms (r.m.s. deviation = 0.001 Å). All six C-S bonds and the central C-C bond in the rings are characterized by π-conjugated lengths, endowing the mol-ecule with high π-conjugation. In the crystal, the mol-ecules are parallel packed, forming columnar stacks along t...

The complete mol-ecule of the title compound, C(19)H(34)N(2)S, is generated by crystallographic twofold symmetry, with the C=S group lying on the rotation axis. A short C-H⋯S contact occurs in the mol-ecule. The five-membered ring is twisted and the cyclo-hexyl ring adopts a chair conformation. The dihedral angle between the mean plane of the five-membered ring and the basal plane of the cyclo-...

A neutral thione extractant, 1,3-diethylimidazole-2-thione (C2C2ImT), was prepared from an ionic liquid (IL), 1,3-diethylimidazolium acetate, and used within a hydrophobic ionic liquid, 1-ethyl-3-methylimidazolium bis(trifluoromethane)sulfonamide ([C2mim][NTf2]), to extract Hg(II) from aqueous solutions of HgCl2 or Hg(OAc)2. Investigations of the extraction mechanism, spectroscopic analyses of ...

We report herein the synthesis of a new biologically active 3,4-dihydropyrimidin-2(1H)-thione derivative (4) from 9-phenanthrenecarboxaldehyde, thiourea, and methyl acetoacetate by Biginelli reaction. The structure synthesized compound was investigated NMR spectroscopy, mass spectrometry, elemental analysis. Moreover, to gain insight into conformation crystal packing, novel dihydropyrimidine al...

In the title compound, C(17)H(18)N(4)O(2)S·H(2)O, the thio-urea derivative is almost planar, with an r.m.s. deviation for the non-H atoms of 0.057 Å. The hydroxyl groups lie to the same side of the mol-ecule as the thione S atom, a conformation that allows the formation of intra-molecular O-H⋯S and O-H⋯N hydrogen bonds. In the crystal structure, the thio-urea and water mol-ecules self-assemble ...
