Abstract
The title zinc alkoxide, bis(μ-2-ethoxyphenolato)-κ3O1,O2:O1;κ3O1:O1,O2-bis[(2-ethoxyphenolato-κ2O1,O2)(pyridine-κN)zinc(II)] toluene hemisolvate, [Zn2(C8H9O2)4(C5H5N)2]·0.5C7H8, crystallizes with two independent complex molecules located on inversion centres and one independent toluene solvent molecule disordered about an inversion centre. The ZnIIatoms are six-coordinated in distorted octahedral geometries with O5N donor sets. The ZnIIions and bridging alkoxide groups are arranged in a diamond Zn2O2core structure. The guetholate (2-ethoxyphenolate) ligands adopt two different coordination modes,viz.peripheral chelating and μ2-bridging. Preliminary investigations of the catalytic activity of the compound in the ring-opening polymerization of L-lactide demonstrate rapid and efficient generation of polylactide.
