1-(3,4-Dichloro-benz-yl)-3-methyl-quinolin-1-ium 7,7,8,8-tetra-cyano-quinodimethanide.

ABSTRACT: In the title salt, C(17)H(14)Cl(2)N(+)·C(12)H(4)N(4) (-), cations and anions stack along the a axis into segregated columns by ?-? stacking inter-actions, with alternating centroid-centroid separations of 3.5957?(7) and 3.7525?(7)?Å for the cation column and 3.4252?(6) and 4.1578?(7)?Å for the anion column. In the cation, the dihedral angle between the benzene ring and the quinoline ring system is 76.35?(4)°. The crystal packing is stabilized by inter-columnar C-H?N hydrogen bonds.

In the title salt, C(17)H(14)Cl(2)N(+)·C(12)H(4)N(4) (-), cations and anions stack along the a axis into segregated columns by π-π stacking inter-actions, with alternating centroid-centroid separations of 3.5957 (7) and 3.7525 (7) Å for the cation column and 3.4252 (6) and 4.1578 (7) Å for the anion column. In the cation, the dihedral angle between the benzene ring and the quinoline ring system is 76.35 (4)°. The crystal packing is stabilized by inter-columnar C-H⋯N hydrogen bonds. ...[more]
