Unprecedented sulfone-functionalized metal-organic frameworks and gas-sorption properties.

Gas storage: A new, sulfone-functionalized dicarboxylate-based ligand (see figure) is capable of directing the formation of novel metal-organic frameworks with unprecedented organic and inorganic secondary building units. A high CO(2) uptake with remarkable selectivity over CH(4), N(2), and H(2) was observed at near-ambient temperature.

Novel coordination polymers based on the tetrathioterephthalate dianion as the bridging ligand.

The first examples of coordination polymers based on the tetrathioterephthalate dianion as the bridging ligand are reported. Two novel compounds, [M(S(2)CC(6)H(4)CS(2))(DMF)(2)](DMF) (M = Zn, Mn; DMF = dimethylformamide), have been synthesized, and their structural and optical properties were investigated.
