Abstract
The X-ray crystal structure of {[nBu(2)Sn(O2CR)](2)O}(2), where R is 4-benz o-15-crown-5, shows the molecule to be centrosymmetric and comprises a cent ral Sn2O2 core to which are linked to two exocyclic tin atoms. Almost symme tric carboxylate bridges provide additional links between pairs of endo- an d exo-cyclic tin atoms and the remaining carboxylate ligands are monodentat e, coordinating the exocyclic tins exclusively. The coordination geometries are distorted trigonal bipyramidal.
