Enhanced H2 adsorption enthalpy in the low-surface area, partially fluorinated coordination polymer Zn5(triazole)6(tetrafluoroterephthalate)2(H2O)2·4H2O

A porous coordination polymer containing zinc, 1,2,4-triazolate, and tetrafluoroterephthalate displays a high physisorptive hydrogen adsorption enthalpy of 8 kJ/mol, as a result of fluorine atoms exposed to the pore surface and the structure's small pore size.
