Selective gas sorption property of an interdigitated 3-D metal-organic framework with 1-D channels

An interdigitated 3-D metal - organic framework, [Cd-3(OH)(2)L-4(H2O)(2)], with 1-D channels was prepared using 4-aminophenyl-1H-tetrazole (HL) and Cd(II) ions, where the host framework shows selective gas sorption behavior that is based on the different nature of the interactions between the gas and the framework rather than on the size-exclusion effect of the micropores.
