(E)-Ethyl 2-cyano-2-(thia­zolidin-2-yl­idene)acetate

The title compound, C8H10N2O2S, was prepared by the reaction of 2-cyano-3,3-bis­(methyl­sulfan­yl)acrylate and 2-amino­ethanethiol at 350 K. The mol­ecular structure and packing are stabilized by N—H⋯O hydrogen-bond inter­actions. All the non-H atoms are nearly in the same plane with the maximum deviation being 0.08 Å

(Z)-4-Amino-1,2,5-oxadiazole-3-carboxamide oxime

The asymmetric unit of the title compound, C3H5N5O2, contains three crystallograpically independent mol­ecules. In the crystal structure, inter­molecular N—H⋯N, N—H⋯O, O—H⋯N and O—H⋯O hydrogen bonds link the mol­ecules into a three-dimensional network

N′-[(5-Methyl­furan-2-yl)methyl­ene]isonicotinohydrazide

The title compound, C12H11N3O2, was prepared by the reaction of isonicotinohydrazide and 5-methyl­furan-2-carbalde­hyde. The pyridine ring makes a dihedral angle of 46.90 (9)° with the mean plane of the furan ring. The crystal packing is stabilized by a bifurcated inter­molecular N—H⋯(N,O) inter­action
