Crystal structure of (E)-1-([1,1'-biphen-yl]-4-yl)-3-(3-nitro-phen-yl)prop-2-en-1-one.

ABSTRACT: In the title compound, C21H15NO3, the mol-ecule has an E conformation about the C=C bond, and the C-C=C-C torsion angle is -178.24?(18)°. In the mol-ecule, the planes of the terminal rings are twisted by an angle of 42.19?(10)°, while the biphenyl part is not planar, with a dihedral angle between the rings of 39.2?(1)°. The dihedral angle between the nitro-phenyl ring and the inner benzene ring is 5.56?(9)°. The 3-nitro group is approximately coplanar with the benzene ring to which it is attached [O-N-C-C = 0.1?(3)°]. In the crystal, mol-ecules are linked via C-H?? inter-actions, involving the terminal benzene rings, forming corrugated layers parallel to (100).

Crystal structure of (E)-1-(4'-meth-oxy-[1,1'-biphen-yl]-4-yl)-3-(3-nitro-phen-yl)prop-2-en-1-one.

Project description:The title compound, C22H17NO4, crystallizes with two independent mol-ecules (A and B) in the asymmetric unit.

The dihedral angle between the nitro-phenyl ring and the inner phenyl ring is 6.50?(9)°. The corresponding values in mol-ecule B are 60.61?(9), 31.07?(8) and 31.05?(9)°. In the crystal, mol-ecules are arranged in a head-to-head manner, with the 3-nitro-phenyl groups nearly parallel to one another. The A and B mol-ecules are linked to one another via C-H?O hydrogen bonds, forming chains lying parallel to (-320) and enclosing R 2 (2)(10) and R 2 (2)(12) ring motifs. The meth-oxy group in both mol-ecules is positionally disordered with a refined occupancy ratio of 0.979?(4):0.021?(4) for mol-ecule A and 0.55?(4):0.45?(4) for mol-ecule B.

Crystal structure of 4,4'-di-nitro-[1,1'-biphen-yl]-2-amine.

Project description:In the title biphenyl derivative, C12H9N3O4, the dihedral angle between the benzene rings is 52.84 (10)°. The nitro group attached to the benzene ring is inclined to the ring by 4.03 (2)°, while the nitro group attached to the amino-substituted benzene ring is inclined to the ring by 8.84 (2)°. In the crystal, mol-ecules are linked by two pairs of N-H⋯O hydrogen bonds, forming chains propagating along [101]. Within the chains, these N-H⋯O hydrogen bonds result in the formation of R22(20) and R22(14) ring motifs. The latter ring motif is reinforced by a pair of C-H⋯O hydrogen bonds, enclosing R21(6) ring motifs. The chains are linked by a second C-H⋯O hydrogen bond, forming a three-dimensional supra-molecular structure.
