An uncommon multicentered ZnI-ZnI bond-based MOF for CO2 fixation with aziridines/epoxides

A novel cluster-based MOF with uncommon multicentered Zn-I-Zn-I bonds {[K1.2Na2.8Zn8I(HL)(12)]center dot 4H(2)O}(n) (HL = tetrazole monoanion) (1) was synthesized, which showed higher stability than the reported Zn-I-Zn-I 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.

Automated summary

The novel cluster-based MOF with uncommon multicentered Zn-I-Zn-I bonds shows higher stability and effectively catalyzes the cyclization of CO2 and compounds with five substituent groups. This study is the first to investigate the catalytic properties of MOFs with multicentered metal-metal bonded clusters as the catalyst.
