A dinuclear zinc complex containing a diamond‐core geometry: [Zn2(μ2‐GueO)2(GueO)2(py)2]·0.5(toluene) (GueOH is guethol)
The title zinc alkoxide, bis(μ‐2‐ethoxyphenolato)‐κ3 O 1,O 2:O 1;κ3 O 1:O 1,O 2‐bis[(2‐ethoxyphenolato‐κ2 O 1,O 2)(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 ZnII atoms are six‐coordinated in distorted octahedral geometries with O5N donor sets. The ZnII ions and bridging alkoxide groups are arranged in a diamond Zn2O2 core 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.
