- Abstract
- <jats:title>Abstract</jats:title><jats:p>Five binuclear complexes with rectangular topology have been synthesized using a nitronyl‐nitroxide ligand (L) functionalized with a pyrazole coordinating group: [Ln<jats:sub>2</jats:sub>(hfac)<jats:sub>2</jats:sub>L<jats:sub>2</jats:sub>], with Ln=Eu (<jats:bold>1</jats:bold>), Gd (<jats:bold>2 a</jats:bold>, <jats:bold>2 b</jats:bold>), Tb (<jats:bold>3</jats:bold>), Dy (<jats:bold>4</jats:bold>), Tm (<jats:bold>5</jats:bold>). The Eu<jats:sup>III</jats:sup> and Tm<jats:sup>III</jats:sup> complexes crystallize in the <jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>/<jats:italic>n</jats:italic> space group, while the Gd<jats:sup>III</jats:sup>, Tb<jats:sup>III</jats:sup>, and Dy<jats:sup>III</jats:sup> derivatives crystalize in <jats:italic>P</jats:italic>‐1 space group. The crystal structures for compounds <jats:bold>2 a</jats:bold>, <jats:bold>3</jats:bold>, <jats:bold>4</jats:bold>, and <jats:bold>5</jats:bold> have been fully solved, while for compounds <jats:bold>1</jats:bold> and <jats:bold>2 b</jats:bold>, the unit cell parameters have been measured and compared with crystals <jats:bold>3</jats:bold> and <jats:bold>5</jats:bold>. Crystals <jats:bold>2 a</jats:bold> (<jats:italic>P</jats:italic>2<jats:sub>1</jats:sub>/<jats:italic>n</jats:italic>) and <jats:bold>2 b</jats:bold> (<jats:italic>P</jats:italic>‐1) are polymorphic forms. In these complexes the nitronyl‐nitroxide ligand bridges two metal ions through one aminoxyl group and the pyrazole fragment. In the five complexes the Ln<jats:sup>III</jats:sup> ions show a coordination number of eight with a triangular dodecahedron geometry. The magnetic properties of all five complexes have been investigated. For compounds <jats:bold>2</jats:bold>, <jats:bold>3</jats:bold>, and <jats:bold>4</jats:bold> the Ln<jats:sup>III</jats:sup>‐Rad interaction was found to be ferromagnetic: <jats:italic>J</jats:italic><jats:sub>GdRad</jats:sub>=2.09(1) cm<jats:sup>−1</jats:sup> [<jats:italic><jats:bold>H</jats:bold></jats:italic>=‐2<jats:italic>J</jats:italic><jats:sub>GdRad</jats:sub>(<jats:italic><jats:bold>S</jats:bold></jats:italic><jats:sub>Gd1</jats:sub><jats:italic><jats:bold>S</jats:bold></jats:italic><jats:sub>Rad1</jats:sub>+<jats:italic><jats:bold>S</jats:bold></jats:italic><jats:sub>Gd2</jats:sub><jats:italic><jats:bold>S</jats:bold></jats:italic><jats:sub>Rad2</jats:sub>], <jats:italic>J</jats:italic><jats:sub>TbRad</jats:sub>=1.93(14) cm<jats:sup>−1</jats:sup>, <jats:italic>J</jats:italic><jats:sub>DyRad</jats:sub>=1.72(14) cm<jats:sup>−1</jats:sup>. The Tm<jats:sup>III</jats:sup>‐Rad coupling is antiferromagnetic (<jats:italic>J</jats:italic><jats:sub>TmRad</jats:sub>=−0.53(1) cm<jats:sup>−1</jats:sup>). For the Tb<jats:sup>III</jats:sup>, Dy<jats:sup>III</jats:sup>, and Tm<jats:sup>III</jats:sup> complexes the effects of the crystal field have been taken into account in the fitting procedure.</jats:p>
