Bis[(E)-2-(3-hydr-oxy-4-methoxy-phen-yl)ethen-yl]-1-methyl-quinolinium tetra-iodidozincate(II) methanol solvate.


ABSTRACT: In the title compound, (C(19)H(18)NO(2))(2)[ZnI(4)]·CH(3)OH, 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 [ZnI(4)](2-) anion displays a very slightly distorted tetra-hedral geometry. There are intra-molecular O-H?O hydrogen bonds between the hydr-oxy and meth-oxy groups in each cation which generate S(5) ring motifs. In the crystal structure, cations are linked together by O-H?O hydrogen bonds and weak C-H?O inter-actions, whereas the anions are linked to the cations through weak C-H?I inter-actions. The asymmetric unit also contains a methanol solvent mol-ecule 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?? and ?-? inter-actions [centroid-centroid distances 3.6054?(15) and 3.6057?(15)?Å].
