[N′-(4-Dec­yl­oxy-2-oxido­benzyl­­idene)-3-hy­dr­oxy-2-naphtho­hydrazidato-κ3N,O,O′]di­methyl­tin(IV): crystal structure and Hirshfeld surface analysis

The title diorganotin compound, [Sn(CH3)2(C28H32N2O4)], features a distorted SnC2NO2 coordination geometry almost inter­mediate between ideal trigonal–bipyramidal and square-pyramidal. The dianionic Schiff base ligand coordinates in a tridentate fashion via two alkoxide O and hydrazinyl N atoms; an intra­molecular hy­droxy-O—H⋯N(hydrazin­yl) hydrogen bond is noted. The alk­oxy chain has an all-trans conformation, and to the first approximation, the mol­ecule has local mirror symmetry relating the two Sn-bound methyl groups. Supra­molecular layers sustained by imine-C—H⋯O(hy­droxy), π–π [between dec­yloxy-substituted benzene rings with an inter-centroid separation of 3.7724 (13) Å], C—H⋯π(arene) and C—H⋯π(chelate ring) inter­actions are formed in the crystal; layers stack along the c axis with no directional inter­actions between them. The presence of C—H⋯π(chelate ring) inter­actions in the crystal is clearly evident from an analysis of the calculated Hirshfeld surface.
