Four Zn atoms are bridged through μ4-O to form [Zn4O] clusters, which are further linked to form a 2D layer n etwork through shari ng Zn as vertexes. 1 exhibits high thermal stability up to 280 ℃ and keeps stable in comm on solve nts and water solutions with pH ranging from 1 to 13. The catalytic studies reveal that compound 1 exhibits excellent catalytic activity for cycloaddition of CO2 with epoxides into cyclic carb on ates un der mild conditions. Furthermore, 1 dem on strates good gen erality in CO2 coupli ng reactio n with extensive epoxides. Importantly, 1 can be reused for at least five times without significant reduction in catalytic ability.展开更多
