New iron tetrazolate frameworks
Abstract
<p>The exploration of the FeF<sub>3</sub>/FeF<sub>2</sub>-H<em>amtetra</em>z-HF system in dimethylformamide by solvothermal synthesis evidences two isostructural 3D hybrid fluoroferrates. They are prepared from the same starting mixture at two different synthesis temperatures: 120 °C for [H<em>dma</em>]·(Fe<sub>4</sub><sup>II</sup>Fe<sup>III</sup>F<sub>8</sub>(H<sub>2</sub>O)<sub>2</sub>(<em>amtetraz</em>)<sub>4</sub>) (<strong>1</strong>) and 140 °C for [H<em>dma</em>]<sub>1.5</sub>·(Fe<sub>4.5</sub><sup>II</sup>Fe<sub>0.5</sub><sup>III</sup>F<sub>7</sub>(H<sub>2</sub>O)(HCOO)(<em>amtetraz</em>)<sub>4</sub>) (<strong>2</strong>). Both compounds are characterized by single crystal X-ray diffraction, X-ray thermodiffraction, TGA analysis, Mössbauer spectrometry and SQUID magnetometry. They crystallize in the monoclinic system and are built from two distinct chains connected by aminotetrazolate anions. The first chain <sub>∞</sub>(Fe<sup>II</sup>FN<sub>4</sub>) is common to <strong>1</strong> and <strong>2</strong> and can be found in numerous fluorides. In the second chain <sub>∞</sub>(Fe<sub>3</sub>X<sub>12</sub>) (X = F, N, O), iron cations adopt both valence states Fe(II)/Fe(III). The hydrolysis of DMF implies the formation of a [H<em>dma</em>]<sup>+</sup> cation and a (HCOO)<sup>−</sup> anion. The presence of Fe<sup>3+</sup> in both phases is evidenced by <sup>57</sup>Fe Mössbauer spectrometry. The magnetic properties are studied and two transitions from a paramagnetic regime to a long range ordered state below 30 K and 5 K are identified.</p>
