Magnetic Tensor Anisotropy in a Low-Symmetry Copper(II) Chelate
Some anisotropic parameters of the spin Hamiltonian for copper doped into single crystals of orthorhombic bis-(N-methylsalicylaldiminato) nickel(II) are presented and discussed in terms of what can and what cannot be inferred from the directional properties of the g tensor and three hyperfine tensors. The most remarkable finding in this study is that the in-plane g anisotropy is unusually large, and the principal in-plane axes are oriented approximately along the metal—ligand bonds, unlike the optical absorption anisotropy and contrary to the previous findings for the g tensors of similar chelates.
