A novel cluster-based MOF with uncommon multicentered Zn-Zn bonds {[KNaZn(HL)]·4HO} (HL = tetrazole monoanion) (1) was synthesized, which showed higher stability than the reported Zn-Zn bonded compounds. Moreover, 1 can effectively and circularly catalyze the cyclization of CO 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.
合成了一种具有罕见多中心锌-锌键的新型基于簇的金属有机框架{[KNaZn(HL)]·4H₂O}（HL = 四唑单阴离子）(1)，其稳定性高于已报道的锌-锌键合化合物。此外，1可以有效且循环催化CO与具有五个取代基的氮丙啶或环氧化物的环化反应。重要的是，这是首次研究以多中心金属-金属键合簇作为催化剂的金属有机框架的催化性能。
