Abstract: A Mn-based rod metal–organic framework (MOF), ROD-6, with a new lrk net is synthesized. It represents an unusual type of MOF topology containing both a 1-periodic secondary building unit (rod SBU) and a polytopic linker (here 1,3,6,8-tetrakis(p-benzoic acid)pyrene), and also exhibits high stability (up to 485 8C) and unusual CO2 uptake behaviour and selectivity despite the lack of strong interacting sites, demonstrated by the low and increasing heat of adsorption.
