Abstract:

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 Ni-II 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.
