| description | The synthesis and characterization of two novel redox-active MOFs/CPs based on 3d transition metal ions and 3,6-ditriazolyl-2,5-dihydroxybenzoquinone (trz<sub>2</sub>An) are reported herein. By combining trz<sub>2</sub>An with Ni<sup>II</sup> and Mn<sup>II</sup> ions via the hydrothermal method, two phases, formulated as [Ni<sub>2</sub>(trz<sub>2</sub>An)<sub>2</sub>]·2.5H<sub>2</sub>O (<b>1</b>) and [Mn(trz<sub>2</sub>An)(H<sub>2</sub>O)]·1.5H<sub>2</sub>O (<b>2</b>), are obtained. Both compounds crystallize as neutral polymeric 3D frameworks, where the metal ions are coordinated through the oxygen atoms of the anilate linkers forming either straight (<b>1</b>) or zig-zag (<b>2</b>) 1D chains. In particular, (<b>1</b>) is a MOF, where these chains are connected through the nitrogen atom at the 4 position of the triazolyl group, which completes the coordination sphere of each metal ion, affording a 3D structure containing a void volume of 28.7% and voids that can be useful for the sorption of small molecules. Interestingly, (<b>1</b>) and (<b>2</b>) show a redox behavior due to the presence of the anilate linker, being reduced electrochemically in the −0.7 to −0.9 V range due to the benzoquinone–semiquinone one-electron reduction and magnetic behavior dominated by antiferromagnetic interactions in the anilate 1D chains. |
