(E)-Ethyl 2-cyano-3-(furan-2-yl)acrylate
There are two independent mol-ecules in the asymmetric unit of the title compound, C(10)H(9)NO(3), in both of which, all non-H atoms except for the methyl C atom lie nearly in the same plane [maximum deviations = 0.094 (3) and 0.043 (2) Å]. In the crystal, each independent mol-ecules is linked by pairs of C-H⋯O inter-actions, generating inversion dimers with R(2) (2)(10) ring motifs.

The C=C bond in the title compound, C(14)H(15)NO(4), is in an E configuration. With the exception of the methyl C atoms, the non-H atoms of the mol-ecule all lie approximately on a plane (r.m.s. deviation = 0.096 Å). π-π stacking is observed between parallel benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.7924 (8) Å.

All the non-H atoms of the title compound, C(10)H(10)N(2)O(2), are nearly in the same plane with a maximum deviation of 0.093 (1) Å. In the crystal, adjacent mol-ecules are linked by pairs of inter-molecular N-H⋯O hydrogen bonds, generating inversion dimers with R(2) (2)(14) ring motifs.

In the title compound, C(12)H(12)N(2)O(2)S, there are S-H⋯N and N-H⋯O hydrogen-bond inter-actions. The N-H⋯O hydrogen bond is bifurcated, with the hydrogen being simultaneously donated to two equivalent O atoms, forming one intra- and one inter-molecular N-H⋯O bond with an R(1) (2)(4) motif. The motif of the S-H⋯N hydrogen bond is R(2) (2)(12).

The title compound, C(12)H(10)N(2)O(6), was synthesized via a Knoevenagel condensation and crystallized from ethanol. In the crystal, strong classical inter-molecular O-H⋯O hydrogen bonds and weak C-H⋯N contacts link the mol-ecules into ribbons extending along [010]. Intra-molecular O-H⋯O and C-H⋯N contacts support the planar conformation of the mol-ecules (mean deivation 0.0270 Å).
