(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
