The SnIV cation in the title compound, [Sn(CH3)2(C10H8NO)2], is N,O-chelated by two 2-methylquinolin-8-olate anions and coordinated by two methyl groups in a skew-trapezoidal bipyramidal geometry. In the molecule, the two quinoline ring systems are twisted to one another at 10.91 (18)°. The dimethyltin skeleton [C-Sn-C = 149.6 (2)°] is bent over the longer edge of the trapezoid that is defined by the four chelating atoms. Weak intermolecular C-H...O hydrogen bonding occurs in the crystal.
