| description | Organic–inorganic hybrid materials built by inorganic and organic building units have attracted intensive interest in the past decades due to unique chemical and physical properties. However, rare organic–inorganic hybrid materials show excellent permanent magnetic properties. Here, we develop a facile chemical solution method to bottom-up synthesize a new hybrid (Fe<sub>2</sub>Se<sub>3</sub>)<sub>2</sub>[Fe(dien)<sub>2</sub>]<sub>0.9</sub>. This hybrid phase with the space group <i>P2<sub>1</sub>/c</i> (14) possesses a rodlike shape with a diameter of 100–2000 nm and a length of 5–50 µm. The hybrid rods are ferrimagnetic with a Curie temperature (<i>T</i><sub>C</sub>) of 11 K. They show a high coercivity (<i>H</i><sub>C</sub>) of 4.67 kOe and a saturation magnetization (<i>M</i><sub>S</sub>) of 13.5 emu/g at 2 K. Compared with orthorhombic (FeSe<sub>2</sub>)<sub>2</sub>Fe(dien)<sub>2</sub>, the excellent magnetic performance of the hybrid rods is ascribed to the monoclinic hybrid structure built by Fe(dien)<sub>2</sub> complexes and Fe<sub>2</sub>Se<sub>3</sub> double chains. Our study provides guidance for connecting inorganic fragments of FeSe<sub>2</sub> single chains, Fe<sub>2</sub>Se<sub>3</sub> double chains or β-Fe<sub>3</sub>Se<sub>4</sub> layers with Fe(dien)<sub>2</sub> complexes for organic–inorganic hybrid phases with varied crystal structures and magnetic properties. |
