4-{[(E)-(3-Phenyl-1H-pyrazol-4-yl)methylidene]amino}-1H-1,2, 4-triazole-5(4H)-thione

Abstract

In the title compound, C 12H 10N 6S, a weak intra-molecular C - H?S hydrogen bond stabilizes the mol-ecular conformation. The pyrazole and triazole rings form a dihedral angle of 17.82 (8) . The molecule adopts an E configuration with respect to the central C=N double bond. In the crystal, inter-molecular N - H?N and N - H?S hydrogen bonds link molecules into chains propagating in [20 ].
