In the title complex, [Sn(C(17)H(10)ClNO(2))Cl(2)(CH(3)OH)], the Sn(IV) atom features a distorted octa-hedral geometry defined by the O,N,O'-donors of the dianion, two Cl atoms and the methanol O atom. The six-membered chelate ring has a half-chair conformation with the Sn atom lying 0.449 (4) Å out of the plane defined by the remaining atoms (r.m.s. deviation = 0.0238 Å). Supra-molecular helical chains along [100], mediated by O-H⋯O hydrogen bonds, feature in the crystal packing. Chains are linked by C-H⋯O, C-H⋯Cl and π-π [centroid-centroid distance = 3.598 (2) Å] inter-actions.
