Abstract

In the solid state, the title compound, di-mu-hydroxo-1:2 kappa(2) O;-3:4 kappa(2) O-dihydroxo-1 kappa O,4 kappa O-octakis(2-methyl-2-phenylpropyl)-1 kappa(2) C,2 kappa(2) C,3 kappa(2) C,4 kappa(2) C-di-mu(3)-oxo-1:2:3 kappa(3) O;2:3:4 kappa(3) O-tetratin(IV), [Sn4O2 (OH)(4) (C10H13)(8)], forms centrosymmetric dimeric [(Neophyl(2)SnOH)(Neophyl(2)SnOH)O](2) molecules (Neophyl = 2-methyl-2-phenylpropyl), with an almost planar Sn-O framework that adopts a ladder-type structure consisting of three four-membered rings. The hydroxyl groups are shielded by the organic groups, which prevent them from further condensation and from the formation of hydrogen bonds.
