Figure 4
Eight symmetry-independent adsorption sites in MOF-5, each partially occupied by Ar atoms, as identified by single-crystal X-ray diffraction at 30 K. Sites α–∊ shown in (a)–(e) are in close proximity to framework atoms. Nitrogen molecules only populate sites α, γ and ∊ at 30 K, but instead populate sites β and δ alongside α at higher temperatures.
