Imprismed metals : Hydrothermal crystallization of Fe and Co oxalates from extremely concentrated KBr solutions yield a coordination network where the paramagnetic metal ions are in rare coordination geometries (see structure). Both materials show a strong 1D magnetic character and for the Fe II derivative no long‐range order is seen above 2 K, making it a candidate for a Spin 2 quasi‐1D quantum antiferromagnet.
