摘要：
The X-ray crystal structure of {[nBu(2)Sn(O2CR)](2)O}(2), where R is 4-benzo-15-crown-5, shows the molecule to be centrosymmetric and comprises a central Sn2O2 core to which are linked to two exocyclic tin atoms. Almost symmetric carboxylate bridges provide additional links between pairs of endo- and exo-cyclic tin atoms and the remaining carboxylate ligands are monodentate, coordinating the exocyclic tins exclusively. The coordination geometries are distorted trigonal bipyramidal.
