An uncommon multicentered ZnI–ZnI bond-based MOF for CO2 fixation with aziridines/epoxides†
Abstract
A novel cluster-based MOF with uncommon multicentered ZnI–ZnI bonds {[K1.2Na2.8ZnI8(HL)12]·4H2O}n (HL = tetrazole monoanion) (1) was synthesized, which showed higher stability than the reported ZnI–ZnI bonded compounds. Moreover, 1 can effectively and circularly catalyze the cyclization of CO2 and aziridines or epoxides with five substituent groups. Importantly, this is the first time that the catalytic properties of MOFs with multicentered metal–metal bonded clusters as the catalyst have been studied.
