In the title compound, (C19H18NO2)2[ZnI4]·CH3OH, each cation is nearly planar and exists in an E configuration, the dihedral angles between the quinolinium systems and the benzene rings being 1.78 (10) and 5.44 (10)° for the two cations.The [ZnI4]2− anion displays a very slightly distorted tetrahedral geometry.
There are intramolecular O—H.O hydrogen bonds between the hydroxy and methoxy hindirochakkahaniya.com groups in each cation which generate S(5) ring motifs.In the crystal structure, cations are linked kicker pro comp 10 together by O—H.O hydrogen bonds and weak C—H.
O interactions, whereas the anions are linked to the cations through weak C—H.I interactions.The asymmetric unit also contains a methanol solvent molecule which is linked to one of the cations by an O—H.O hydrogen bond and the anion through an O—H.
I hydrogen bond.The crystal is further stabilized by C—H.π and π–π interactions [centroid–centroid distances 3.6054 (15) and 3.
6057 (15) Å].
