A spin-canted NiII4-based metal–organic framework with gas sorption properties and high adsorptive selectivity for light hydrocarbons

The reaction of nickel(II) nitrate with isonicotinic acid and 2,6-dimethyl-pyridine-3,5-dicarboxylic acid affords a novel, tetranuclear nickel(II)-based metal–organic framework that exhibits spin-canted antiferromagnetism with a canted angle of 1.65° and high adsorptive selectivity for light hydrocarbons.
