Bis(4-fluoro­benzyl)­tin(IV) ester of pyruvic acid salicyl­hydrazone

In the title complex, bis­[μ-salicyl­aldehyde (1-carboxyl­ato­ethyl­idene)­hydrazonato(2−)]­bis­[ethano­lbis(4-fluoro­benzyl)­tin(IV)], [Sn₂(C₇H₆F)₄(C₁₀H₈N₂O₄)₂(C₂H₆O)₂], each central Sn^IV atom has a distorted pentagonal–bipyramidal configuration, being coordinated by three O atoms and one N atom from the pyruvic acid salicyl­hydrazone ligands, one O atom from an ethanol mol­ecule and two axial C atoms from trans 4-fluoro­benzyl groups, thus forming a dimeric mol­ecule, which sits on a crystallographic center of symmetry. Intramolecular hydrogen bonds contribute to the stability and compactness of the crystal structure.
