“…This configuration has been previously shownt of avor pentacoordinate complexes. [32] At horough analysiso fs tructural details at the molecular level revealed some differences between the two species. For 1,t he four nitrogen atoms (N4 and N5) of Me 4 cyclam lie in the same plane, and the Ni atom is displaced by 0.327 out of this plane toward the azide nitrogen atom N1, which occupies an axial position.…”

The magnetic properties of the pentacoordinate [M (Me cyclam)N ] (Me cyclam=tetramethylcyclam; N =azido; M=Ni, Co) complexes were investigated. Magnetization and EPR studies indicate that they have an easy plane of magnetization with axial anisotropy parameters D close to 22 and greater than 30 cm for the Ni and Co complexes, respectively. Ab initio calculations reproduced the experimental values of the zero-field splitting parameters and allowed the orientation of the anisotropy tensor axes with respect to the molecular frame to be determined. For M=Ni, the principal anisotropy axis lies along the Ni-N direction perpendicular to the Ni(Me cyclam) mean plane, whereas for M=Co it lies in the Co(Me cyclam) mean plane and thus perpendicular to the Co-N direction. These orientations match one of the possible solutions experimentally provided by single-crystal cantilever torque magnetometry. To rationalize the geometry and its impact on the orientation of the anisotropy tensor axis, calculations were carried out on model complexes [Ni (NCH) ] and [Co (NCH) ] by varying the geometry between square pyramidal and trigonal bipyramidal. The geometry of the complexes was found to be the result of a compromise between the electronic configuration of the metal ion and the structure-orienting effect of the Me cyclam macrocycle. Moreover, the orientation of the anisotropy axes is mainly dependent on the geometry of the complexes.
