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 angstrom. 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.
