Ethyl 3-benzoyl-2-hydroxyprop-2-enoate
In the title compound, C(12)H(12)O(4), the dihedral angle between the plane through the phenyl ring and the mean plane of the side chain is approximately 14°. The mol-ecules, which contain an intra-molecular O-H⋯O hydrogen bond, are linked end-to-end by weak C-H⋯O inter-molecular hydrogen-bonding contacts, forming infinite one-dimensional chain systems in the crystal structure.

The title compound, C(23)H(18)O(4), is a 1,4-enedione compound which contains a naphthalene ring and a benzene ring. The dihedral angle between the ring systems is 74.9 (2)°. In the crystal, the mol-ecules form π-π stacking inter-actions between naphthalene rings of inversion-related mol-ecules, with an inter-planar spacing of 3.499 (2) Å.

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.

In the title compound, C(20)H(18)N(2)O(2), weak inter-molecular C-H⋯O and C-H⋯N inter-actions generate a chain that runs parallel to the b axis and incorporates C(7) and R(2) (2)(15) graph-set motifs. The supra-molecular aggregation is completed by the presence of weak C-H⋯π inter-actions.
متن کاملEthyl (2Z)-3-hydroxy-3-(4-nitrophenyl)prop-2-enoate
The title compound, C11H11NO5, is essentially planar, with an r.m.s. deviation of 0.06 Å. The mol-ecular structure is stabilized by an intra-molecular O-H⋯O hydrogen bond. In the crystal, molecules are linked by two pairs of C-H⋯O hydrogen bonds, forming sheets, lying parallel to (101), which enclose R 4 (4)(26) ring motifs.
