Abstract

By employing oxalate to modify the connectivity of formate perovskites, novel perovskite-like cai topological 3D antiferromagnets [A]2[FeIIIFe2II(HCOO)7(C2O4)] were synthesized. The reduction of π-conjugated systems in organic ammonium increases their structural freedom, adjusting the phase transition of these complexes.
