摘要

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 蟺-蟺 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.
