1. A method of capturing chemical species, comprising:
contacting a metal-organic framework with a fluid composition including one or more of SO2, CO2, and H2O,
wherein the metal-organic framework is characterized by the chemical formula NiNbOF5(pyrazine)2·x(Solv) or NiAlF5(H2O)(pyrazine)2·x(solv),
wherein the metal-organic framework comprises a square grid pillared by an inorganic building block, wherein the square grid is Ni(pyrazine)2 and the inorganic building block is selected from [NbOF5]2− or [AlF5(H2O)]2−; and
sorbing one or more of SO2, CO2, and H2O from the fluid composition on the metal-organic framework.
