The reaction of 4-(dimethylamino)pyridine, picolinic acid and stannic chloride yields the title monosolvated salt, (C₁₃H₁₀NO)[SnCl₄(C₆H₄NO₂)]·CH₃OH. The Sn^IV atom is N,O-chelated by the picolinate ion in a cis-SnNOCl₄ octahedral geometry. The cation is linked to the methanol solvent molecule by an O-HO hydrogen bond; the solvent molecule itself is a hydrogen-bond donor to the uncoordinating carboxylate O atom of the anion. The cations and anions are linked by weak N-HCl interactions, forming a chain running along the b axis.
