8-Hy-droxy-2-methyl-quinolinium diiodido(2-methyl-quinolin-8-olato-κN,O)zincate(II) methanol monosolvate.

ABSTRACT: The anion of the title salt, (C(10)H(10)NO)[Zn(C(10)H(8)NO)I(2)]·CH(3)OH, has its metal atom N,O-chelated by the deprotonated 2-methyl-8-hy-droxy-quinoline ligand. The hy-droxy unit of the cation is a hydrogen-bond donor to the alkoxide O atom of the tetra-hedrally coordinated anion, whereas the ammonium cation acts as a hydrogen-bond donor to the methano-lic O atom. In the crystal, adjacent ion pairs and solvent mol-ecules are linked by a methanol-halogen O-H⋯I hydrogen bond, generating a chain running along the a axis.
