10-Hy-droxy-benzo[h]quinolin-1-ium tetra-chlorido(pyridine-2-carboxyl-ato-κ(2)N,O)stannate(IV) methanol monosolvate.
The reaction of 4-(dimethyl-amino)-pyridine, picolinic acid and stannic chloride yields the title monosolvated salt, (C(13)H(10)NO)[SnCl(4)(C(6)H(4)NO(2))]·CH(3)OH. The Sn(IV) atom is N,O-chelated by the picolinate ion in a cis-SnNOCl(4) octa-hedral geometry. The cation is linked to the methanol solvent mol-ecule by an O-H⋯O hydrogen bond; the solvent mol-ecule itself is a hydrogen-bond donor to the uncoordinating carboxyl-ate O atom of the anion. The cations and anions are linked by weak N-H⋯Cl inter-actions, forming a chain running along the b axis.
