Abstract

Low temperature magnetization studies were carried out on polycrystalline pellets of two nickel(II) complexes of 1,4-diazacycloheptane having different coordination geometries. The diamagnetic-magnetic transitions observed at low temperatures is attributed to electronic transitions within the 3d orbitals of the Ni²⁺ ion perturbed by crystal field effects resulting from considerable overlap of wave functions associated with the metal and donor atoms in addition to the existence of long-range superexchange interactions.
