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. Each mol-ecule exists as an E isomer with C-C=C-C torsion angles of -175.69 (17) and -178.41 (17)° in A and B, respectively. In mol-ecule A, the planes of the terminal benzene rings are twisted by an angle of 26.67 (10)°, while the biphenyl unit is non-planar, the dihedral angle between the rings being 30.81 (10)°. 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.

(E)-3-(2-Chloro-phen-yl)-1-(4-nitro-phen-yl)prop-2-en-1-one.

Project description:In the title compound, C(15)H(10)ClNO(3), a substituted chalcone, the 2-chloro-phenyl and 4-nitro-phenyl rings make a dihedral angle of 26.48 (6)°. The nitro group makes a dihedral angle of 11.64 (7)° with the plane of the benzene ring to which it is bound. Weak intra-molecular C-H⋯O and C-H⋯Cl inter-actions involving the enone groups generate S(5) ring motifs, which help to stabilize the planarity of the 3-(2-chloro-phen-yl)prop-2-en-1-one segment of the mol-ecule.

Crystal structure of 4,4'-bis-[3-(piperidin-1-yl)prop-1-yn-1-yl]-1,1'-biphen-yl.

Project description:The title compound, C28H32N2, (I), is one of a second generation of compounds designed and synthesized based on a very potent and selective α9α10 nicotinic acetyl-choline receptor antagonist ZZ161C {1,1'-[[1,1'-biphen-yl]-4,4'-diylbis(prop-2-yne-3,1-di-yl)]bis-(3,4-di-methyl-pyridin-1-ium) bromide}, which has shown analgesic effects in a chemotherapy-induced neuropathy animal model. Compound (I) was synthesized by the reaction of 4,4'-bis-(3-bromo-prop-1-yn-1-yl)-1,1'-biphenyl with piperidine at room temperature in aceto-nitrile. The single-crystal used for X-ray analysis was obtained by dissolving (I) in a mixture of di-chloro-methane and methanol, followed by slow evaporation of the solvent. In the crystal of (I), the biphenyl moiety has a twisted conformation, with a dihedral angle of 25.93 (4)° between the benzene rings. Both piperidine head groups in (I) are in the chair conformation and are oriented so that the N-atom lone pairs of each piperidine group point away from the central biphenyl moiety.
