The asymmetric unit in the title thio­urea derivative, C13H19N3S, comprises three independent mol­ecules (A, B and C). The thio­urea groups are superimposable for the three mol­ecules, but there are significant conformational differences. Mol­ecules A and B are approximate mirror images of each other, and mol­ecule C has an inter­mediate conformation. The dihedral angles between the thio­urea groups and the phenyl rings are 52.10 (5), 63.29 (5) and 66.46 (6)° in mol­ecules A, B and C, respectively. Each independent mol­ecule self-associates into a supra­molecular chain along [100] via N—H⋯S hydrogen bonds. Mol­ecules of A and B assemble into layers four mol­ecules thick in the ac plane via C—H⋯S and C—H⋯π inter­actions. Mol­ecules of C self-assemble into layers in the ac plane via C—H⋯S inter­actions. The layers stack along the b axis with no specific inter­actions between them.

Comment top

1,4-Disubstituted piperazine derivatives are known for their diverse biological activities such as a CNS stimulant (Al Hussainy et al., 2011; Moussa et al., 2011), anti-convulsant (Kamiński et al., 2011), anti-microbial (Sheng et al., 2011), anti-cancer (Yang et al. 2011) and histamine antagonist (Liu et al., 2011). In continuation of our interest in the chemical and pharmacological properties of 1,4-piperazine derivatives (Kadi et al., 2010), we synthesized the title compound, (I), as an intermediate for potential chemotherapeutic agents.

Three independent molecules comprise the asymmetric unit of (I), Fig. 1. There are significant differences in conformation between these as highlighted in Fig. 2. The independent molecules containing the S1 and S2 are approximately mirror images of each other and the conformation of the S3 containing molecule is intermediate between those of the others. The dihedral angles formed between the thiourea moiety and the phenyl rings are 52.10 (5), 63.29 (5) and 66.46 (6)°, respectively. Each piperazine ring has a chair conformation.

Each independent molecule self-associates into a supramolecular chain via N—H···S hydrogen bonds, Table 1. Chains are orientated along the a axis and an example is illustrated for the S1-containing molecule in Fig. 3. In the crystal packing, the S1- and S2-containing chains are connected into layers four molecules thick via C—H···S and C—H···π interactions. The S3-containing molecules are also connected into layers via C—H···S interactions. Globally, layers, which are formed in the ac plane, stack along the b axis, Fig. 4, with no specific interactions between them.

Experimental top

Methyl isothiocyanate (3.66 g, 0.05 mol) was added to a solution of 1-benzylpiperazine (8.81 g, 0.05 mol) in ethanol (15 ml). The mixture was stirred for 5 min. at room temperature and allowed to stand for 1 h. The separated crude product was filtered, washed with cold ethanol, dried and crystallized from ethanol to yield 11.60 g (93%) of the title compound as colourless crystals. M.p.: 365–367 K.

Refinement top

Carbon-bound H-atoms were placed in calculated positions [C—H = 0.95 to 0.98 Å, Uiso(H) = 1.2 to 1.5Ueq(C)] and were included in the refinement in the riding model approximation. The amino H-atoms were located in a difference Fourier map, and were refined with a distance restraint of N–H 0.88 (1) Å; their Uiso values were refined.
