{4-Hydroxy-N′-[(2-oxido-1-naphthyl-κO)methylidene]benzohydrazidato-κ2N′,O}dimethyltin(IV)

Two independent but very similar molecules comprise the asymmetric unit of the title compound, [Sn(CH3)2(C18H12N2O3)]. Each Sn atom is coordinated by two methyl groups and two O atoms and an N atom from the dinegative tridentate ligand. The resultant C2NO2 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) ] interactions. The layers are connected along the c axis via C—H...O interactions.
