Crystal structure of 4-chloro-2-nitrobenzoic acid with 4-hydroxyquinoline: a disordered structure over two states of 4-chloro-2-nitrobenzoic acid–quinolin-4(1H)-one (1/1) and 4-hydroxyquinolinium 4-chloro-2-nitrobenzoate

Crystal Structure of Schiff base Compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol

Single crystals of Schiff base compound 2-[(2-chloro-4-nitrophenyl) iminomethyl] phenol (1) were grown by the slow evaporation technique at room temperature. The crystal structure of the title compound was determined by single crystal X-ray diffraction. The title compound crystallizes in the monoclinic system, space group P21, with two symmetry independent molecules. Intramolecular O-H···N hydr...

Crystal structure of 4-chloro-2-iodo­aniline

In the crystal structure of the title compound, C6H5ClIN, the amino group engages in N-H⋯N hydrogen bonding, creating [100] chains. A Cl⋯I contact is observed [3.7850 (16) Å]. The parallel planes of neigbouring mol-ecules reveal highly offset π-stacking characterized by a centroid-centroid distance of 4.154 (1), a centroid-to-plane distance of 3.553 (3) and ring-offset slippage of 2.151 (6) Å.

2-Chloro-N-(4-chloro-3-iodo­phen­yl)-4-(methyl­sulfon­yl)benzamide

In the title compound, C(14)H(10)Cl(2)INO(3)S, the dihedral angle between the benzene rings is 52.13 (10)°. In the crystal, the components are linked by pairs of N-H⋯O(sulfon-yl) hydrogen bonds into centrosymmetric dimers.

2-Chloro-4-iodo­aniline

The title dihaloaniline, C(6)H(5)ClIN, shows no significant hydrogen bonds nor the commonly observed I⋯I inter-actions in the crystal structure, although an amino group and an I atom are available for such contacts. The crystal structure is stabilized by weak inter-actions involving the amine functionality as donor group and N or halogen atoms as acceptors.
