Abstract: The coordination of benzene-1,3,5-tribenzoate (BTB) and imidazole (Im) with cobalt under basic conditions yields a 2D layered structure, Co3(BTB)1.5(Im)1.35(O)0.5(OH)0.5(H2O)1.65 guests (1), in which the imidazoles are weakly π–π stacked and hydrogen bonded to the adjacent layers affording a 3D supramolecular network. The structure is based on a hexanuclear Co6 building unit which comprises four octahedral and two tetrahedral Co(II) centres. The framework is permanently porous to N2, CO2 and CH4, with the strength of interaction at zero coverage being comparable to that at high loading.
