The cation and the anion in the title salt, (C₆H₁₆N)[SnCl₄(C₆H₄NO₂)], are linked by an N-HO hydrogen bond. The Sn^IV atom in the stannate anion is chelated by the pyridine-2-carboxylate group and exists in a cis-SnCl₄NO octahedral geometry. The cation is disordered over two positions in a 0.564 (1):0.436 (1) ratio.
