{4-Hy­droxy-N′-[(2-oxido-1-naphthyl-κO)methyl­idene]benzohydrazidato-κ(2) N′,O}dimethyl­tin(IV)

Two independent but very similar mol­ecules comprise the asymmetric unit of the title compound, [Sn(CH(3))(2)(C(18)H(12)N(2)O(3))]. Each Sn atom is coordinated by two methyl groups and two O atoms and an N atom from the dinegative tridentate ligand. The resultant C(2)NO(2) donor set defines a coordination geometry inter­mediate between square-pyramidal and trigonal-pyramidal, with a small tendency towards the former. Zigzag chains running along the a axis mediated by O—H⋯N hydrogen bonding characterize the crystal packing. These are connected into layers in the ab plane by a combination of C—H⋯N and π–π [centroid–centroid distances = 3.658 (2) and 3.6740 (18) Å] inter­actions. The layers are connected along the c axis via C—H⋯O inter­actions.
