3-(2-Hy-droxy-eth-yl)-3-methyl-1-(4-methyl-benzo-yl)thio-urea

摘要

The title thio-urea derivative, C 12 H 16 N 2 O 2 S, has a twisted conformation with the dihedral angle between the NC(=S)N and O=CC 6 planes being 35.45?(5)°. The observed conformation allows for an intra-molecular N—H?O hydrogen bond. In the mol-ecular packing, supra-molecular aggregation is based on hy-droxy-O—H?O(carbon-yl) hydrogen bonding and leads to supra-molecular helical chains along the a axis; chains are reinforced by N -methyl-ene-C—H?S and N -methyl-C—H? π (arene) inter-actions. Supra-molecular layers in the ab plane are formed as a result of tolyl-methyl-C—H? π (arene) inter-actions.
