2D coordination polymer composed of 1D {NiII(μ-O)(μ-H2O)NiII}n ferromagnetic chains: Modulation of magnetic properties based on dehydration and rehydration

Synthesis, single-crystal structure and magnetic properties of a 2D coordination compound [Ni(1,3-ADA)(H2O)]n (1) is reported which exhibits tunable magnetic behavior based on dehydration–rehydration. 1 shows ferromagnetic (FM) interaction between NiII ions. Combined detailed experimental and theoretical studies reveal that FM interaction arises due to “orthogonal” magnetic orbitals, which become distorted in desolvated state and suppress the FM interaction.
