| dc.description.abstractEn | The insertion of a [Fe(sal<sub>2</sub>-trien)]<sup>+</sup> complex cation into a 2D oxalate network results in a hybrid magnet with coexistence of magnetic ordering and photoinduced spin-crossover (LIESST effect) in compound [Fe<sup>III</sup>(sal<sub>2</sub>-trien)][Mn<sup>II</sup>Cr<sup>III</sup>(ox)<sub>3</sub>]*(CH<sub>2</sub>Cl<sub>2</sub>) (1). A complete photomagnetic characterization together with a detailed structural analysis of the low-spin (LS) and high-spin (HS) structures of 1 is presented in order to understand such unusual behavior. This very rare and unexpected property in a Fe<sup>III</sup> spin-crossover complex, has been attributed to the strong distortion exhibited by the metastable HS state. Furthermore, 1 has shown that, in contrast to what has been previously proposed, a cooperative spin-crossover is not a necessary condition to observe LIESST effect in Fe<sup>III</sup> compounds. The photo-induced spin conversion of the inserted Fe<sup>III</sup> complex has shown to have a negligible influence on the cooperative magnetic behaviour of the 2D oxalate network. | |
