A Series of Chiral, Polar, Homospin Topological Ferrimagnets: M<sub>3</sub>(OOCH)<sub>5</sub>Cl(OH<sub>2</sub>) (M = Fe, Co, Ni)
An isostructural
series of transition metal-formate-chloride-hydrate
compounds, M<sub>3</sub>(OOCH)<sub>5</sub>ClÂ(OH<sub>2</sub>) (M =
Fe, Co, Ni), have been synthesized using a solvothermal method. These
compounds crystallize in the chiral and polar space group <i>P</i>3<sub>1</sub> and are comprised of three different types
of helical chains of edge-sharing M<sup>2+</sup>-centered octahedra.
All three compounds undergo 3D ferrimagnetic ordering at low temperature,
and the iron and cobalt analogues exhibit field-induced metamagnetic
transitions. The magnetic structure was determined by neutron powder
diffraction, revealing ferromagnetic intrachain coupling and antiferromagnetic
interchain interactions, with the three chains arranged in a two-up/one-down
triangular lattice. As all three chains contain one type of metal
in the same spin state, these compounds are rare examples of homospin
topological ferrimagnets
