In the title compound, C12H11N3O2S, the dihedral angle between the 4H-chromen-4-one ring system and the –CH=N—NH—CS—NH– unit is 6.22 (1)°. In the crystal, inversion dimers linked by pairs of N—H⋯O hydrogen bonds generate R22(14) loops. The dimers are reinforced by a pair of C—H⋯O interactions, which generate R22(10) loops.
Keywords: crystal structure; hydrazinecarbothioamide; 4H-chromen-4-one; biological properties; hydrogen bonding.

1.05 g (0.01 mol) of N-methylhydrazinecarbothioamide was dissolved in 20 ml of hot ethanol and to this 1.74 g of 4-oxo-4H-Chromene-3-carbaldehydein 10 ml of ethanol was added and continuously stirred for a period of 10 min with continuous stirring. The reaction mixture was refluxed for 2 h and allowed to cool whereby shining white was filtered and washed thoroughly with ethanol and then dried in vaccum. The compound was recrystallized from hot ethanol to yield colourless blocks in 92% yield.
All H atoms were fixed geometrically and allowed to ride on their parent C atoms, with C—H distances fixed in the range 0.93–0.97 Å with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for all other H atoms.

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. |

Thiosemicarbazones are of considerable interest because of their versatile chemistry and various biological activites such as antitumor, antibacterial, antiviral, antiamoebic and antimalarial (Kelly et al., 1996). Schiff bases derived from 3-formylchromones have attracted much attention due to their biological functions such as enzyme inhibition (Khan et al., 2009; Tu et al., 2013).
The structure of the title compound (Figure 1) shows that the atoms of both 4H-chromen-4-one and the –CH=N—NH—CS—NH– segments are roughly planar and the largest deviations are -0.144 (2) and -0.114 (2) Å for O2 and C12 respectively. The dihedral angles between 4H-chromen-4-one and –CH=N—NH—CS—NH—C– unit and the benzene ring of 4H-chromen-4-one and –CH=N—NH—CS—NH—C– unit are 6.22 (1) and 7.12 (1)°, respectively.
In the crystal, inversion dimers linked by pairs of N—H···O hydrogen bonds generate R22(14) loops. The dimers are reinforced by a pair of C—H···O interactions, which generate R22(10) loops.
