title: (Z)-{[3-(Hydroxy-meth-yl)-1,3-thia-zolidin-2-yl-idene]amino}formonitrile.
abstract: In the title mol-ecule, C(5)H(7)N(3)OS, all the non-hydrogen atoms except the O atom are almost planar [maximum least squares plane deviation = 0.035 (3) Å for the N atom]. The crystal packing is stabilized by inter-molecular O-H⋯N hydrogen bonds, which link the mol-ecules into inversion dimers.
