Exploring the synthese, structure, and properties of a 3D Mn-MOF based on 4,6-bistriazole isophthalic acid

One three dimensional metal organic framework {[Mn2(BTIA)2(H2O)]·7H2O}n (Mn-1) was synthesized from the multidentate organic linker 4,6-bistriazole isophthalic acid (H2BTIA) and MnCl2·4H2O under solvothermally condition. The structure of 1 exhibits as a three-dimensional framework fabricated by the binuclear subunits [Mn2(COO)2(H2O)] and the organic linkers (H2BTIA). Topologically, it displays a binodal framework with Schläfli symbol (44·62)2(416·612), which contains one dimensional channels along a direction. The magnetic behavior of Mn-1 was investigated, which discloses the antiferromagnetic (AF) interactions between Mn2+ ions with the coupling constant J = −1.38 cm−1. In additin, the porous Mn-MOF shows a small uptake capacity for CO2.
