1,1'-Methyl-enebis{4-[(E)-2-(pyridin-4-yl)ethen-yl]pyridinium} dibromide dihydrate.

ABSTRACT: The chevron-shaped cations of the title hydrated salt, C₂₅H₂₂N₄ ²⁺·2Br^-·2H₂O, are arranged in back-to-back alternating directions to form a zigzag ribbon propagating along the [010] direction. Inter-molecular inter-actions comprising these ribbons are π-π inter-actions between the pyridinium and adjacent pyridyl rings, as well as O-H⋯O hydrogen bonding between water molecules and two adjacent pyridyl N atoms. Half of the cation is generated by the mirror plane. The water O atoms, the central C atom and one Br atom are located on this mirror plane while the other Br atom is on a twofold screw axis.

3-(Ammonio-meth-yl)pyridinium dibromide.

Project description:In the title salt, C(6)H(10)N(2) (2+)·2Br(-), the non-H atoms of the 3-methyl-pyridinium unit of the cation are almost coplanar (r.m.s. deviation = 0.0052 Å). In the crystal, the dications and Br anions are linked by a combination of six hydrogen bonds, viz. one N(py)-H⋯Br, two C-H⋯Br and three H(2)N-H⋯Br, into supra-molecular layers, parallel to the bc plane, composed of alternating R(2) (4)(10) and R(2) (4)(8) loops. Weak π-π inter-actions between cationic rings with centroid-centroid distances of 3.891 (2) Å are also observed.

1,1'-Dimethyl-1,1'-(butane-1,4-di-yl)dipyrrolidinium dibromide methanol disolvate.

Project description:In the title compound, C(14)H(30)N(2) (2+)·2Br(-)·2CH(3)OH, two terminal C atoms of the butane chain are connected to two N atoms of the 1-methyl-pyrollidines, forming a linear diquaternary ammonium cation. The cation lies across a centre of inversion located between the two central C atoms of the butane chain. The asymmetric unit therefore comprises one half-cation, a bromide anion and a methanol solvent mol-ecule. In the crystal structure, the bromide anions are linked to the methanol solvent mol-ecules by O-H⋯Br hydrogen bonds.
