A solution of indazole (1.18 g, 10 mmol) in dry n-hexane (25 ml) was treated with solid NaH (55%, 0.44 g, 10 mmol) under an N2 atmosphere. Liberation of H2 stopped after 3 h stirring. PhNCS (1.2 ml, 10 mmol) was added to the resulting suspension of [Na][Indz] and the reaction was continued overnight at r.t. The suspension was filtered using a fritted funnel and the collected white solid, [Na][PhNCSIndz], was washed with cold n-hexane (3 x 10 ml) and dried in vacuo; yield 2.60 g, 95%. M.p. = 240 °C (melting along with colour change and decomposition). Colourless crystals of (I) were obtained unintentionally as the decomposition product of an authenticated sample of Bu2Sn(PhNCSIndz)2 during attempts to grow crystals from heptane solution in air; M.p. = 90 °C.
All C– and N-bound H atoms were included in the riding-model approximation, with C—H = 0.95 Å and N—H = 0.88 Å, and with Uiso(H) = 1.2Ueq(C, N).
The preparation and crystal structures of series of compounds containing molecules related to the title compound (I), i.e. with the general formula PhNC(=S)R (R = pyrazolyl, 3,5-dimethylpyrazolyl and 3,5-diphenylpyrazolyl) and PhNC(=S)NRR' (R = alkyl or aryl) have been reported recently (Hossaini Sadr, Sardroodi et al., 2005; Hossaini Sadr, Jalili et al., 2005; Henderson et al., 2006). Compound (I) exists as a thione, C8=S1 is 1.6545 (19) Å, and the conformation about the C8—N3 bond is Z. The molecule is non-planar as the phenyl ring is twisted out of the plane of the central chromophore as manifested in the C8/N3/C9/C10 torsion angle of 51.7 (2)°. In the crystal structure, molecules related by 2-fold symmetry associate via N—H···N hydrogen bonds, Table 1. Pairs of molecules are connected by C—H···π interactions [C1—H1···Cg(C9—C14) = 2.47 Å for symmetry operation 1 - x, 1 + y, -z] on either side to form columns parallel to the b axis. Connections between columns are afforded by weak C—H···S interactions; the S1 forms two such contacts with different molecules of the adjacent chain, Table 1. A view of the unit-cell contents is shown in Fig. 2.

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. |

The preparation and crystal structures of series of compounds containing molecules related to the title compound (I), i.e. with the general formula PhNC(=S)R (R = pyrazolyl, 3,5-dimethylpyrazolyl and 3,5-diphenylpyrazolyl) and PhNC(=S)NRR' (R = alkyl or aryl) have been reported recently (Hossaini Sadr, Sardroodi et al., 2005; Hossaini Sadr, Jalili et al., 2005; Henderson et al., 2006). Compound (I) exists as a thione, C8=S1 is 1.6545 (19) Å, and the conformation about the C8—N3 bond is Z. The molecule is non-planar as the phenyl ring is twisted out of the plane of the central chromophore as manifested in the C8/N3/C9/C10 torsion angle of 51.7 (2)°. In the crystal structure, molecules related by 2-fold symmetry associate via N—H···N hydrogen bonds, Table 1. Pairs of molecules are connected by C—H···π interactions [C1—H1···Cg(C9—C14) = 2.47 Å for symmetry operation 1 - x, 1 + y, -z] on either side to form columns parallel to the b axis. Connections between columns are afforded by weak C—H···S interactions; the S1 forms two such contacts with different molecules of the adjacent chain, Table 1. A view of the unit-cell contents is shown in Fig. 2.
