In the title compound, C6H16N+·C15H13N2O2S2−, the thione S atom is in a cis configuration with respect to the phenyl and benzene rings, while it adopts a trans configuration with respect to the carbonyl group. The dihedral angle between the benzene and phenyl rings is 78.81 (2)°. The molecular conformation is stabilized by intramolecular O—H⋯O and N—H⋯S hydrogen bonds, while intermolecular N—H⋯O, N—H⋯N and weak C—H⋯O interactions help to stabilize the crystal structure.

The title compound was synthesized by the reaction of CS2 (1.99 g, 26.29 mmol) with a solution of salicylic acid hydrazide (4 g, 24.09 mmol) in CHCl3 (15 ml) in the presence of triethylamine (2 ml, 24.09 mmol). Benzyl chloride (3.5 ml, 26.30 mmol) was added dropwise to the above clear solution, which was stirred continuously for 2 h at room temperature. The product was obtained on evaporation of the solvent at room temperature. Colorless single crystals of (I) (m.p., 418 K) suitable for X-ray analysis were obtained by slow evaporation of a chloroform solution over a period of 10 days. (Yield 58%). Elemental analysis: Anal.

All H atoms were initially located in a diffrence Fourier map. They were then placed in geometrically idealized positions and constrained to ride on their parent atoms, with C—H = 0.95–0.99 Å; N—H = 0.88Å and O—H = 0.84Å and Uiso(H) = 1.2 Ueq(C,N) or 1.5Ueq(Cmethyl,O).
Dithiocarbazates and their derivatives have attracted much attention as they have potential applications as antitumor, antibacterial and antifungal agents (Scovill et al., 1982,1984, West & Pannell, 1989, Gou et al., 1990). Interest in these systems is also stimulated by their unusual physico-chemical (Abu-Raquabah et al.1992, Marchi et al., 1990) and chemotherapeutic properties (Ali & Livingston, 1974). Although N'-acyl hydrazine carbodithioates are structurally similar to the derivatives of dithiocarbazates, little data is available on their synthesis and characterization. As part of our ongoing investigation, we report here the synthesis and
of the title compound (I) which was obtained from the reaction of salicylic acid hydrazide, CS2 and benzyl chloride in the presence of triethylamine.The molecular structure of (I), together with atom labeling scheme is shown in Fig 1. The Hydrazinic H atom on N1 is trans with respect to the carbonyl group and cis with respect to the thione S atom. The C7—N1 distance of 1.329 (4) Å is intermediate between 1.47 Å for a C—N single bond and 1.29 Å for a double bond (Boga et al., 1999). The N1—N2 distance of 1.396 (3) Å [single bond (N—N) = 1.45 Å and double bond (N=N) = 1.25 Å] and the O2—C7 distance of 1.257 (4) Å suggest extensive delocalization in this part of the molecule. In the π interaction (Fig 2) [C5—H5···Cg = 140.65°, H5···Cg = 2.976 Å and C5···Cg = 3.759 Å, where Cg is the centroid of the phenyl ring]. The is stabilized by intramolecular O—H···O and N—H···S hydrogen bonds while intermolecular N—H···O, N—H···N and weak C—H···O interactions help stabilize the crystal structure.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Dithiocarbazates and their derivatives have attracted much attention as they have potential applications as antitumor, antibacterial and antifungal agents (Scovill et al., 1982,1984, West & Pannell, 1989, Gou et al., 1990). Interest in these systems is also stimulated by their unusual physico-chemical (Abu-Raquabah et al.1992, Marchi et al., 1990) and chemotherapeutic properties (Ali & Livingston, 1974). Although N'-acyl hydrazine carbodithioates are structurally similar to the derivatives of dithiocarbazates, little data is available on their synthesis and characterization. As part of our ongoing investigation, we report here the synthesis and structure determination of the title compound (I) which was obtained from the reaction of salicylic acid hydrazide, CS2 and benzyl chloride in the presence of triethylamine.
The molecular structure of (I), together with atom labeling scheme is shown in Fig 1. The Hydrazinic H atom on N1 is trans with respect to the carbonyl group and cis with respect to the thione S atom. The C7—N1 distance of 1.329 (4) Å is intermediate between 1.47 Å for a C—N single bond and 1.29 Å for a double bond (Boga et al., 1999). The N1—N2 distance of 1.396 (3) Å [single bond (N—N) = 1.45 Å and double bond (N=N) = 1.25 Å] and the O2—C7 distance of 1.257 (4) Å suggest extensive delocalization in this part of the molecule. In the crystal structure, there is a weak C—H···π interaction (Fig 2) [C5—H5···Cg = 140.65°, H5···Cg = 2.976 Å and C5···Cg = 3.759 Å, where Cg is the centroid of the phenyl ring]. The molecular conformation is stabilized by intramolecular O—H···O and N—H···S hydrogen bonds while intermolecular N—H···O, N—H···N and weak C—H···O interactions help stabilize the crystal structure.
