Abstract:
Four cobalt(II) and zinc(II) cationic metal-organic frameworks (MOFs) based on bridging 1,4-diazabicyclo[2.2.2]octane N,N′-dioxide (odabco) are synthesized. In a mixture of N,N-dimethyl formamide (DMF) and water acidified with nitric acid, [Co(odabco)3](NO3)2 compound (I) is obtained. The synthesis in a mixture of dimethyl acetamide (DMA), acetic acid, and water results in the formation of [Co2(odabco)3(OAc)2](NO3)2 (II, OAc– - acetate) MOF containing coordinated acetate anions. In DMF acidified with hydrochloric acid, [Zn2(odabco)3Cl2](NO3)2·DMF·2H2O, compound (III) containing coordinated chloride anions is obtained. In a mixture of DMA and water acidified with nitric acid, [Zn(odabco)2](NO3)2(Hodabco)NO3·0.83H2O MOF (IV) is synthesized. The structures of I-IV are determined by single crystal X-ray diffraction. In all structures, odabco acts as a bridging ligand forming cationic layered (II, III) or 3D (I, IV) coordination lattices and protonated guest chains {–Hodabco+–}n in IV. The cavities in the lattices of I-IV have total solvent-accessible volumes of 10%, 11%, 28%, and 56% respectively and accomodate NO−3
counterions. Compounds I and II are the first examples of coordination polymers based on Co2+ and the odabco ligand. The influence of the synthetic conditions of I-IV on their structure is analyzed in comparison to each other and the previously published examples of structures with this ligand.
