Abstract :
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.
