Tetra-chloridodi-μ3-oxido-tetra-kis-(μ2-propan-2-olato-κ(2) O:O)ditin(II)ditin(IV).

The centrosymmetric tetranuclear title molecule, [Sn4(C3H7O)4Cl4O2], contains two types of Sn atoms, Sn(II) and Sn(IV). The Sn(II) atom has a trigonal-pyramidal coordination environment and is bonded to two O atoms from two iso-propano-late groups and one μ3-oxide atom. The Sn(IV) atom has an octa-hedral coordination environment, formed by two chloride atoms, two μ3-oxide atoms and two O atoms from iso-propano-late groups.
