N-Carbethoxy-N'-(3-phenyl-1H-1,2,4-triazol-5-yl)thiourea
Abstract
The title compound, C12H13N5O2S, exists in the 3-phenyl-5-thioureido-1H-1,2,4-triazole tautomeric form stabilized by intramolecular hydrogen bonding between the endocyclic NH H atom and the thioureido S atom. The molecular structure is also stabilized by intramolecular N-H...O=C hydrogen bonds arranged in an S(6) graph-set motif within the carbethoxythiourea moiety. The mean planes of the phenyl and 1,2,4-triazole rings make a dihedral angle of 7.61 (11)deg. In the crystal, the molecules form two types of inversion dimers. Intermolecular hydrogen bonds are arranged in R22(6) and R22(8) graph-set motifs, together forming a network parallel to (111).
