Design and Synthesis of Stable Cobalt-Based Weak Ferromagnetic Framework with Large Spin Canting Angle
It still remains
a great challenge to design and construct framework-structured weak
ferromagnets with large canting angle which is an effective approach
for high performance magnets. According to the strategy of antisymmetric
interaction causing spin canting, we report the design of four cobalt
compounds, which were tested by X-ray single crystal diffraction,
TGA, PXRD, and magnetic measurement. Single-crystal structure analysis
reveals that compound <b>1</b> has a 2D structure, complex <b>2</b> has a 3,4-connected 3D framework, and complex <b>3</b> exhibits a 3D net structure with rare 3,5-connected 2-nodal β-SnF<sub>2</sub> topology and the solvent MeOH trapped in the 3D channels
as guests. The magnetic property of <b>3</b> is spin canting
just as designed, with <i>T</i><sub>N</sub> about 4.0 K
and large canting angle of 14.8°. Highly stable compound <b>3</b> sustains its framework in air for more than 12 months, in
which the guest MeOH molecules can be replaced by water to form complex <b>4</b>
