Crystal structure of diethyl 2-acet-oxy-2-[3-(4-nitro-phen-yl)-3-oxo-1-phenyl-prop-yl]malonate.

ABSTRACT: In the racemic title compound, C24H25NO9, the dihedral angle between the planes of the two benzene-ring systems is 80.16 (6)°, while the side-chain conformation is stabilized by a methyl-ene-carboxyl C-H⋯O hydrogen bond. Weak inter-molecular C-H⋯O hydrogen bonds form inversion dimers [graph set R 2 (2)(16)] which are linked into chains extending along a. Further C-H⋯O hydrogen bonding extends the structure along b through cyclic R 2 (2)(10) motifs. Although no π-π aromatic ring inter-actions are present in the structure, C-H⋯π ring inter-actions across c generate an overall three-dimensional supra-molecular structure.

Synthesis and structure of (<i>E</i>)-<i>N</i>-(4-meth-oxy-phen-yl)-2-[4-(3-oxo-3-phenyl-prop-1-en-1-yl)phen-oxy]acetamide.

Project description:The title compound N-(4-meth-oxy-phen-yl)-2-[4-(3-oxo-3-phenyl-prop-1-en-1-yl)phen-oxy]acetamide, C24H21NO4, was prepared from reaction of N-(4-meth-oxy-phen-yl)-2-chloro-acetamide and (E)-3-(4-hy-droxy-phen-yl)-1-phenyl-prop-2-en-1-one, which was obtained from the reaction of 4-hy-droxy-benzaldehyde and aceto-phenone. The structure of the title compound was determined by IR, 1H-NMR, 13C-NMR and HR-MS spectroscopic data and further characterized by single-crystal X-ray diffraction. The asymmetric unit contains four mol-ecules, each displaying an E-configuration of the C=C bond. The dihedral angle between the phenyl rings in each mol-ecule varies between 14.9 (2) and 45.8 (2)°. In the crystal, C-H⋯O hydrogen-bonding inter-actions link the mol-ecules into chains running along the [001] direction. In addition, C-H⋯π inter-actions further stabilize the crystal packing. A Hirshfeld analysis indicates that the most important contributions to the surface contacts are from H⋯H (43.6%), C⋯H/H⋯C (32.1%) and O⋯H/H⋯O (18.1%) inter-actions.

4-(4-Chloro-phen-yl)-1-(2-hydr-oxy-2,2-di-phenyl-acet-yl)thio-semicarbazide.

Project description:The asymmetric unit of the title compound, C(21)H(18)ClN(3)O(2)S, contains two mol-ecules in which the bond lengths and angles are almost identical. Intra-molecular N-H⋯S hydrogen bonds result in the formation of two five-membered rings. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers; these dimers are linked via inter-molecular O-H⋯S hydrogen bonds, leading to infinite corrugated layers parallel to the bc plane through R(2) (2)(16) ring motifs.
