Ethyl (2E)-2-cyano-3-(1-methyl-1H-pyrrol-2-yl)prop-2-enoate
The 15 non-H atoms of the title compound, C(11)H(12)N(2)O(2), are approximately coplanar, the r.m.s. deviation being 0.145 Å. The major deviation from coplanarity is seen in a twist between the ethene (E configuration) and pyrrole rings [C-C-N-C torsion angle = -8.26 (18)°]. The carbonyl O and cyano N atoms are syn to each other. In the crystal, supra-molecular linear tapes linked by C-H⋯O and ...

In the title compound, C(7)H(10)N(2)O(2), the dimethyl-amino group is twisted slightly relative to the acrylate fragment, forming a dihedral angle of 11.6 (1)°. In the crystal, molecules are linked via pairs of bifurcated C-H/H⋯O hydrogen bonds, forming inversion dimers, which are further connected by C-H⋯N hydrogen bonds into chains along the a-axis direction.

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.

The title compound, C16H16N4O2, crystallizes with two mol-ecules in the asymmetric unit, one of which shows disorder of the acetate group over two sets of sites in a 0.799 (2):0.201 (2) ratio. The phenyl group has a similar but opposite sense of twist relative to the pyrazole ring in the two mol-ecules, as indicated by the syn N-N-Car-Car (ar = aromatic) torsion angles of 39.7 (2) and -36.9 (2)...
متن کامل(E)-Ethyl 2-cyano-3-(2,4-dimethoxyphenyl)prop-2-enoate
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.
