1-(2-Hydroxyethyl)-3-phenylthiourea

The title compound, C9H12N2OS, was obtained unexpectedly in a multicomponent reaction of an equimolar ratio of phenyl isothiocyanate, malononitrile and aminoethanol. The -C(H-2)N(H)-(CS)-N(H)-methylthiourea-methane group is almost normal to the phenyl ring, with a dihedral angle of 71.13 (9)degrees. The N-C-C-O torsion angle is 72.8 (2)degrees. In the crystal, molecules are connected by N-H center dot center dot center dot O, O-H center dot center dot center dot S and N-H center dot center dot center dot O hydrogen bonds, forming a three-dimensional network
