The crystal structure of 1-(2-hydroxy-5-meth­oxy­phen­yl)ethanone 4,4-di­methyl­thio­semicarbazone

The asymmetric unit of the title compound, C(12)H(17)N(3)O(2)S, contains two independent mol­ecules, A and B. Both mol­ecules are nearly planar with the dihedral angle between the mean planes of the thio­amide group and benzene ring being 7.5 (1)° in A and 4.3 (2)° in B. In each mol­ecule, the hy­droxy group participates in intra­molecular O—H⋯N hydrogen bonding, while the amino H atom is not involved in hydrogen bonding because of the steric hinderence caused by two neighboring methyl groups. In the crystal, the individual molecules are linked by weak C—H⋯O hydrogen bonds, forming A–A and B–B inversion dimers. The dimers are linked via C—H⋯π inter­actions which help stabilize the packing.
