Crystal structure of 5-methyl-N-phenyl-1,3,4-thiadiazole-2-amine

The crystal structure of 5-methyl-N-phenyl-1,3,4-thiadiazole-2-amine (I) is determined. The molecule of compound I is non-planar; the mean square plane of its phenyl cycle is located at an angle of 22.8° with respect to the planar thiadiazole fragment. The studied compound forms infinite chains in the crystal due to the translation along a, in which the molecules are bound by N-H...N and C-H...N bonds. Along with the van der Waals interaction, there is also a X-H...Cg (π ring) interaction between the chains in the crystal.
