In the title compound, [PdCl(2)(C(6)H(6)N(2)O(2))(2)], the Pd(II) atom is coordinated in a distorted square-planar geometry by two N atoms from two 4-nitro-aniline ligands and two Cl atoms in a trans arrangement. Inter-molecular N-H⋯Cl hydrogen bonds involving the amino groups and chloride anions lead to a chain along [100]. These chains are further self-assembled into a three-dimensional netwo...

The title compound, C(23)H(18)ClN(3)O, was synthesized by the reaction of 4-chloro-aniline and 4-benzoyl-3-methyl-1-phenyl-1H-pyrazol-5(4H)-one. The terminal benzene rings are twisted at dihedral angles of 48.3 (2), 71.4 (2) and 36.1 (2)° with respect to the central eight-atom methyl-pyrazolone/amino-methyl-ene unit. An intra-molecular N-H⋯O hydrogen bond stabilizes the planar conformation [mea...

In the structure of the the title compound, C(13)H(9)Cl(2)NO, the N-H and C=O groups are mutually trans. Furthermore, the conformation of the C=O group is syn to the ortho-chloro group in the benzoyl ring, while the N-H bond is anti to the meta-chloro group in the aniline ring. The amide group forms dihedral angles of 89.11 (19) and 22.58 (37)°, respectively, with the benzoyl and aniline rings,...

A practical Cu-catalyzed direct ortho-halogenation of anilines under aerobic conditions has been developed. The reaction shows typically excellent mono-substitution selectivity, high ortho-regiocontrol and large functional group tolerance.

Infrared photodissociation spectra of aniline+–M (M = thiophene, furan and phenol) are measured in the 2700–3700 cm–1 region and analyzed by density functional theory calculations. Only a structure with a π-type hydrogen bond is found for aniline+–thiophene. Two structural isomers are identified for aniline+–furan and aniline+–phenol, which have either a π-type or a σ-type hydrogen bond, where ...

In the title compound, C(14)H(14)N(2)O(2), the angle between the mean plane of the N-methyl-3-nitro-aniline system (r.m.s. deviation = 0.0185 Å) and the p-tolyl unit is 89.79 (4)°. In the crystal, hydrogen-bonded chains running along [10-1] are generated by the linking of neighbouring mol-ecules via N-H⋯O and C-H⋯O hydrogen bonds involving the 3-nitro-aniline systems and forming R(2) (2)(8) mot...

In the title compound, C(19)H(16)N(2)O(3)S·C(2)H(6)O, the 4-hy-droxy-benzyl-idene group is oriented at dihedral angles of 73.17 (7) and 77.06 (7)° with respect to the aniline groups. The sulfonyl group make dihedral angles of 44.89 (13) and 59.16 (12)° with the adjacent aniline groups. In the crystal, a two-dimensional polymeric network parallel to (010) is formed by N-H⋯O, O-H⋯N and O-H⋯O hydr...

In the structure of the title mol-ecular salt, C10H18N2 (2+)·2NO3 (-), the dinitrate salt of 4-(N,N-di-ethyl-amino)-aniline, the two ethyl groups lie almost perpendicular to the plane of the benzene ring [the ring-to-ethyl C-C-N-C torsion angles are -59.5 (2) and 67.5 (3)°]. The aminium groups of the cation form inter-species N-H⋯O hydrogen bonds with the nitro O-atom acceptors of both anions, ...

The asymmetric unit of the title compound, C6H5Cl2N·2C11H11Cl2NO, is composed of one mol-ecule of an enamino-ketone [i.e. -(2,6-dichloro-phenyl-amino)-pent-3-en-2-one] and half a mol-ecule of 2,6-dichloro-aniline, the whole mol-ecule of the latter component being generated by twofold rotational symmetry. In this latter mol-ecule, there are two intra-molecular N-H⋯Cl contacts. In the enamino-ket...

In the title compound {systematic name: 4-chloro-N-[1-(1H-imidazol-1-yl)-2-propoxyethyl-idene]-2-(trifluoro-meth-yl)aniline}, C(15)H(15)ClF(3)N(3)O, the dihedral angle between the aniline and imidazole ring planes is 81.80 (4)°. In the crystal structure, weak inter-molecular C-H⋯X (X = N, O or F) hydrogen bonds and C-H⋯π inter-actions help to consolidate the packing.
