The title compound, C 20 H 14 N 12 S 2 , was synthesized by the reaction of 3-hydrazino-1H-1,2,4-triazole with phenyl isocyanate in benzene and by ring closure in an alkaline medium. Intermolecular N-HÁ Á ÁN hydrogen bonds are observed and these form a five-membered ring.

All interatomic distances in the title compound, C~13~H~15~N~3~O~2~S, are normal. The 1,2,4-triazole ring is planar and is inclined at 46.50 (6)° to the phenyl ring. The ethoxycarbonylmethyl group is also close to being planar and is inclined at 87.54 (9)° to the 1,2,4-triazole ring. The crystal was
In the title complex, [Sn(C 6 H 5 ) 3 (C 8 H 7 N 4 S)], all bond lengths and angles show normal values. The Sn centre is fourcoordinated by three C atoms [Sn-C 2.119 (6)-2.133 (6) A ˚] and one N atom [Sn-N 2.107 (5) A ˚] in a distorted tetrahedral geometry. The crystal packing exhibits no classical
In the molecule of the title compound, C 9 H 9 N 3 O, the dihedral angle between the planar rings is 7.49 (3) . In the crystal structure, intermolecular N-HÁ Á ÁO hydrogen bonds link the molecules into dimers, which may be effective in the stabilization of the crystal structure.
