1,3-Bis(3-methyl­phen­yl)thio­urea: triclinic polymorph

The title compound, C(15)H(16)N(2)S, crystallizes with two molecules in the asymmetric unit. The crystallographic behaviour of the two isomers is different. The mol­ecules are dimerized, forming an R (2) (2)(8) ring motif due to inter­molecular N—H⋯S hydrogen bonds. C—H⋯S hydrogen bonds form R (2) (...

Sumario:The title compound, C(15)H(16)N(2)S, crystallizes with two molecules in the asymmetric unit. The crystallographic behaviour of the two isomers is different. The mol­ecules are dimerized, forming an R (2) (2)(8) ring motif due to inter­molecular N—H⋯S hydrogen bonds. C—H⋯S hydrogen bonds form R (2) (2)(12) ring motifs. In one molecule, the dihedral angle between the benzene rings is 62.54 (6)°, whereas in the other it is 79.54 (6)°. The H atoms of one of the methyl groups in each molecule are disordered over two sites, with occupancy ratios of 0.52 (3):0.48 (3) and 0.60 (3):0.40 (3).
