title: High-spin [2 x 2] [Fe(III)2Ni(II)2] heterometallic square grid with an S = 3 ground state.
abstract: A [2 x 2] heterometallic [Fe(III)2Ni(II)2] ferrimagnetic, square-grid complex has been synthesized by the self-assembly reaction of a mononuclear Fe(III) precursor with Ni(NO3)2. Intramolecular antiferromagnetic exchange through the resulting hydrazone O-bridging framework (M-O-M 133.3-136.4 degrees) leads to an S = 3 ground state. Structural and magnetic properties are discussed.
