NOVELTY - A metal-organic material comprises complex of metal-linker-metal oxide.    USE - For capturing a polarizable gas i.e. carbon dioxide in a gas; for separating components in a gas (claimed); and in the system such as post-combustion system, pre-combustion system, natural gas upgrading system, and separation system.    ADVANTAGE - The material is inexpensive and particularly facile to synthesize; is extraordinary stable and retains their crystallinity in water over a wide range of pH; is stable in air and boiling water for months; and provides faster and stronger absorption of carbon dioxide than other gases in the gas mixture.    DETAILED DESCRIPTION - A metal-organic material (MOM), comprising (M(L)2P')n, where (M(L)2P')n has a 6-connected 48.67 topology net.    M=Cu2+, Zn2+, Co2+, Ni2+, Mn2+, Zr2+, Fe2+, Ca2+, Ba2+, Cs2+, Pb2+, Pt2+, Pd2+, Ru2+, Rh2+, Cd2+, Mg+2, Al+3, Fe+3, Cr3+, Ru3+ or Co3+;    L=bifunctional N donor group that serves as a linker;    P'=oxyanion with angular geometry;    n=1-1018.    INDEPENDENT CLAIMS are included for the following:    (1) capturing a polarizable gas in a gas, involving exposing the gas to a (M(L)2P')n; and capturing the polarizable gas in the MOM;    (2) a system for capturing a polarizable gas in a gas, comprising a first structure including a (M(L)2P')n; and a second structure for introducing the gas to the first structure, where the polarizable gas is removed from the gas after the exposure to the MOM to form a modified gas, where the second structure flows the modified gas away from the first structure;    (3) separating components in a gas, involving exposing a gas including a first component and a second component to a metal-organic material (MOM), where the MOM has a greater relative affinity for the first component over a second component; and capturing the first component in the MOM; and    (4) a system for separating components in a gas, comprising a first structure including metal-organic material (MOM); and a second structure for introducing the gas to the first structure, where first component is removed from the gas after the exposure to the hydrophobic MOM to form a modified gas, where the second structure flows the modified gas away from the first structure.
