| Abstract Scope |
As a major result of fossil fuel burning, CO2 capture and storage (CCS) technology is critical to mitigate global warming. Ni(CN)4-based metal organic framework (MOF) compounds could be effective sorbent materials. The structure of Ni(3-methyl-4,4’-bipyridine)[Ni(CN)4] (Ni-BpyMe) was determined to be different when dimethyl sulfonate (DMSO) and acetone (followed by evacuation) were used as solvent of crystallization. The structure of Ni-BpyMe consists of a 3-D net built from extended 2-D [Ni(CN)4] groups. These layers are connected via the BpyMe ligands at the six-fold Ni2 sites. Ni1 has a four-fold coordination environment. The interesting feature of this structure is that instead of locating the -CH3 group in one position of the pyridine ring, it appears in two positions in both cases due to disorder. Sorption study indicated the compound to be a relatively rigid MOF as no hysteresis loop was observed. A comparison of the two structures will be given. |
