Microporous metal–organic layer built from pentanuclear tetrahedral units: gas sorption and magnetism†
Abstract
Presented herein is a porous layer motif 1 built from pentanuclear tetrahedral Ni-clusters with accessible metal centers. Activated 1 exhibits a high selectivity of 19.8 at 273 K and 1 bar for the separation of CO2 over CH4. Magnetic measurement shows the overall antiferromagnetic coupling between Ni(II) ions for 1.
