Abstract

In the title compound, (C9H8N)[FeCl4], the tetra­chloro­ferrate(III) anion lies on a mirror plane, whereas the quinolinium cation has inversion symmetry as the result of orientational disorder. In the crystal structure, C—H⋯Cl inter­actions between the ions form zigzag ribbons along the b axis. These ribbons are linked via Fe—Cl⋯π inter­actions, forming a three-dimensional network.

Abstract

The asymmetric unit of the title compound, (C10H10N)2[FeCl4]Cl, consists of two 2-methyl­quinolinium cations, a tetra­chloro­ferrate(III) anion with one of the Cl atoms disordered, and a chloride anion. In the crystal structure, there are π–π stacking interactions between the cations in an ABBA arrangement, N—H⋯Cl hydrogen bonds, and Fe—Cl⋯π inter­actions.

Abstract

The Fe3+ centre in the complex anion of the title compound, [(C4H9)4N][FeBrCl3], is surrounded by three chloride anions and one bromide anion. The Br atom in [FeBrCl3]− is disordered, replacing Cl atoms. The Fe and N atoms lie on a twofold rotation axis.

Abstract

The asymmetric unit of the title compound, (C10H10N)2[FeCl4]Cl, contains two protonated 8-methyl­quinolinium cations, one chloride anion and one tetra­chloridoferrate(III) anion. The mean Fe—Cl distance is 2.1880 (7) A. The two 8-methyl­quinolinium cations and chloride anion are connected via N—H⋯Cl hydrogen bonds. Furthermore, there are stacking inter­actions between cations. N—H⋯Cl hydrogen bonds link two 8-methyl­quinolinium cations. The bromido analogue is isostructural with the title compound.

Abstract

The asymmetric unit of the title compound, (C10H10N)2[FeBr4]Br, contains two protonated 8-methyl­quinolinium cations, one bromide anion and one tetra­bromido­ferrate anion. The mean Fe—Br distance is 2.3338 (6) A. The 8-methyl­quinolinium cations are planar and are inclined at a dihedral angle of 5.25 (9)° with respect to each other. The two 8-methyl­quinolinium cations and bromide anion are connected via N—H⋯Br hydrogen bonds. Furthermore, there are short C—H⋯Br contacts and π⋯π stacking inter­actions between cations. The N—H⋯Br hydrogen bonds link the mol­ecules into chains along the [210] direction.
