Multifunctional MOFs through CO_2 fixation: a metamagnetic kagome lattice with uniaxial zero thermal expansion and reversible guest sorption

摘要

The properties of atmospheric CO_2 fixation, metamagnetism, reversible guest adsorption and zero thermal expansion have been combined in a single robust MOF, [Cu_3(bpac)_3(CO_3)_2](ClO_4)_2·H_2O (1·H_2O). This compound is a ditopically-bridged copper carbonate kagome lattice where desolvation of the MOF allows subtle tuning of the metamagnetic and uniaxial ZTE behaviour.
