Dimethyl (E)-2-(N-phenylacetamido)but-2-enedioate
The title compound, C(14)H(15)NO(5), was obtained from the reaction of acetanilide with dimethyl acetyl-enedicarboxyl-ate in the presence of potassium carbonate. The C=C double bond adopts an E configuration and the geometry around the amide N atom is almost planar rather than pyramidal (mean deviation of 0.0032 Å from the C(3)N plane). The packing of the mol-ecules in the crystal structure is ...

The structure of N,N'-bis(2-hydroxybenzylidene)-2,2-dimethyl-1,3-propanediamine, C19H22N2O2, has been studied at low temperature (120K) by means of single-crystal X-ray diffraction. Solving the structure shows an orthorhombic unit cell, with P212121 space group, Z = 4, a = 6.1046 (4) Å, b = 15.8349 (11)</e...
متن کاملCrystal structure of 2,5-dimethyl-3-(2-methylphenylsulfinyl)-1-benzofuran
The title compound, C17H16O3S, crystallized with two independent mol-ecules (A and B) in the asymmetric unit. The dihedral angle between the benzo-furan ring system [r.m.s. deviation of 0.013 (1) for A and 0.009 (1) Å for B] and the 2-methyl-phenyl ring is 83.88 (5) for A and 86.94 (5)° for B. In the crystal, the B mol-ecules are linked into a chain along the b-axis direction by C-H⋯O hydrogen ...

متن کاملCrystal structure of 3-amino-5,5-dimethyl-2-[(E)-2-nitroethenyl]cyclohex-2-en-1-one
The asymmetric unit of the title compound, C10H14N2O3, contains two independent mol-ecules with similar conformations. In the both mol-ecules, the cyclo-hexene rings adopt the same envelope conformation with the flap C atoms lying 0.658 (3) and 0.668 (3) Å from the mean planes formed by the remaining atoms. In the crystal, adjacent mol-ecules are connected via N-H⋯O hydrogen bonds and weak C-H⋯...
