Three ionic metal-organic frameworks (MOFs) with pore-capsulated Co(CO)4− anions, formulated as [Co(bix)3][Co(CO)4]2 (1), [Co(bibp)3][Co(CO)4]2 (2), and [Co(bmibp)2][Co(CO)4]2 (3); (bix = 1,4-bis(imidazol-1-yl-methyl)-benzene); bibp = 4,4′-bis(imidazolyl)biphenyl); bmibp = 4,4′-bis(2-methyl-imidazolyl)biphenyl), have been facilely synthesized for the first time through direct reactions of Co2(CO)8 with the respective bis(imidazole) ligands under mild hydro(solvo)thermal conditions. Single-crystal X-ray diffraction analysis reveals distinct structural motifs among the frameworks: MOF 1 exhibits a single pcu net, MOF 2 features a 3-fold interpenetrating pcu net, both based on 6-connected Co2+ centers and ditopic bix or bibp ligands, while MOF 3 forms a 2-fold interpenetrating sql layer constructed by 4-connected Co2+ ions and bmibp linkers. The [Co(CO)4]− anions reside within the channels of the cationic frameworks. Moreover, these MOFs, characterized by periodically ordered tetracarbonylcobaltate arrays, demonstrate notable thermal stability and maintain structural integrity in air, water, and alkaline solutions for several days.
