Octa-butyl-bis{(E)-2-[4-(2-hydroxy-benzyl-ideneamino)phen-yl]acetato}di-μ(2)-methoxo-di-μ(3)-oxido-tetra-tin(IV).

The title compound, [Sn(4)(C(4)H(9))(8)(C(15)H(12)NO(3))(2)(CH(3)O)(2)O(2)], is a centrosymmetric dimer and displays a ladder type structural motif. There are four Sn(IV) centres which can be divided into two sorts, viz. two endocyclic and two exocyclic. The endo- and exocyclic Sn(IV) centres are linked by bidentate deprotonated methanol and μ(3)-O atoms. Each exocyclic Sn(IV) centre is also coordinated by a monodentate 2-[4-(2-hydroxy-benzyl-idene-amino)phen-yl]acetate ligand. Parts of the butyl groups were found to be disordered over two sets of sites.
