Novel rare earth metal–zinc heterotrinuclear complexes have been synthesized, which showed high efficiency and selectivity in initiating the copolymerization of CO₂ and cyclohexene oxide under mild conditions. Significant cooperation between rare earth metal and zinc centres that account for the good performance is observed. Copolymers of high polycarbonate content (up to 99%) as well as high molecular weight (up to 295800 g mol⁻¹) were obtained at 25 °C under 0.7 MPa pressure of CO₂.
