The asymmetric unit of the title compound, C17H14N2S, consists of two crystallographically independent molecules with similar conformations. The dihedral angles between the phenyl rings are 89.32 (5) and 82.80 (5)° in the two molecules. In the crystal, molecules are linked by C—Hπ interactions, forming a three-dimensional network.

The title solvated complex, [Ru(η5-C5H5)(N3){P(C6H5)3}2]·0.5CH2Cl2, displays a typical piano-stool geometry about the RuII atom. The bond lengths and angles of the cyclopentadienyl and phosphane ligands are very similar to that of the unsolvated complex [Taqui Khan et al. (1994). Acta Cryst. C50, 502–504]. The azide anion displays similar N—N distances of 1.173 (3) and 1.156 (3) Å and has an N—N—Ru angle of 119.20 (15)°, indicating a greater contribution of the canonical form Ru—N=N(+)=N(-) for the bonding situation. An intramolecular C—HN hydrogen-bonding interaction between one ortho H atom of a phosphane ligand and the N atom coordinating to the metal is observed. A similar intermolecular interaction is observed between a meta H atom of a phosphane ligand and the terminal azide N atom of a neighbouring complex. Finally, two C—HN interactions exists between the H atoms of the dichloromethane solvent molecule and the terminal N atom of two azide anions. The solvent molecule is located about a twofold rotation axis and shows disorder of the Cl atoms with an occupancy ratio of 0.62 (3):0.38 (3).
