A novel isoreticular oxamato-based manganese(II)-copper(II) open metal-organic framework H 2O@iso1 featuring a pillared square/octagonal layer structure with alternating open and closed octagonal pores has been rationally prepared. The open-framework topology is responsible for a large selectivity in the separation of small gas (CO 2 over CH 4) and vapor molecules (CH 3OH over CH 3CN and CH 3CH 2OH). H 2O@iso1 displays a long-range three-dimensional ferromagnetic ordering with a drastic variation of the critical temperature as a function of the guest molecule [T C < 2.0 K (CO 2@iso1 and CH 4@iso1) and T C = 6.5 (CH 3OH@iso1) and 21.0 K (H 2O@iso1)].
