Temperature identification on two 3D Mn(ii) metal–organic frameworks: syntheses, adsorption and magnetism†
Two new 3-D NaCl-type frameworks of [AmineH+][Mn(HCOO)3] (AmineH+ = N(CH3)4+ for 1 and AmineH+ = NH4+ for 2) have been synthesized at different temperatures. The N(CH3)4+ cation was generated in situ by the decomposition of a large number of DMF molecules. The potential porosity of the coordination framework of 1 has been estimated using a computational method based on Connolly's algorithm, indicating that compound 1 presents a kinetic radius greater than 1.61 Å. Because unremovable guest cations are clogged in the channels, 1 presents no significant adsorption for CO2 gas upon desolvation by long-duration thermal activation. In addition, the magnetic behavior of the two compounds was explored.
