Multinuclear Zinc-Magnesium Hydroxide Carboxylates: A Predesigned Model System for Copolymerization of CO₂ with Epoxides.

ABSTRACT: Among numerous catalysts in the ring-opening copolymerization of epoxides with carbon dioxide (CO₂), zinc dicarboxylate complexes are the most common type, and in the family of metal-based homogeneous catalysts, zinc and magnesium complexes have attracted widespread attention. We report on the synthesis and structural characterization of a zinc-magnesium benzoate framework templated by the central hydroxide anion with μ₃-κ²:κ²:κ² coordination mode, [ZnMg₂(μ₃-OH)(O₂CPh)₅]_n (n = 1 or 2). The resulting heterometallic system forms stable Lewis acid-base adducts with tetrahydrofuran (THF) and cyclohexene oxide (CHO), which crystallize as the hexanuclear zinc-magnesium hydr
