4. Magnetic anisotropy and relaxation behavior of six-coordinate tris(pivalato)-Co( ii ) and -Ni( ii ) complexes

   Experimental and theoretical studies of magnetic anisotropy and relaxation behavior of six-coordinate tris(pivalato)-Co( ii ) and -Ni( ii ) complexes (NBu 4 )[M(piv) 3 ] (piv = pivalate, M = Co, 1 ; M = Ni, 2 ), with a coordination configuration at the intermediate between an octahedron and a trigonal prism, are reported. Direct current magnetic data and high-frequency and -field EPR spectra (HFEPR) of 1 have been modeled by a general Hamiltonian considering the first-order orbital angular momentum, while the spin Hamiltonian was used to interpret the data of 2 . Both 1 and 2 show easy-axis magnetic anisotropies, which are further supported by ab initio calculations. Alternating current (ac) magnetic susceptibilities reveal slow magnetic relaxation at an applied dc field of 0.1 T in 1 , which is characteristic of a field-induced single-ion magnet (SIM), but 2 does not exhibit single-ion magnetic properties at 1.8 K. Detailed analyses of relaxation times show a dominant contribution of a Raman process for spin relaxation in 1 .

5. Charge transfer and slow magnetic relaxation in a series of cyano-bridged FeIII4MII2 (M = Fe II , Co II , Ni II ) molecules

   https://doi.org/10.1039/c8qi01245h  

   Wang, Jin-Hua ; Vignesh, Kuduva R. ; Zhao, Jia ; Li, Zhao-Yang ; Dunbar, Kim R. ( February 2019 , Inorganic Chemistry Frontiers)

   The synthesis, single-crystal structures and magnetic properties of three new cyano-bridged complexes [FeIII4MII2] (M = Fe II , Co II , Ni II ) are reported. Electronic absorption spectroscopy reveals the occurrence of intervalence charge transfer for [FeIII4FeII2]. Field-induced slow magnetic relaxation behavior is exhibited for [FeIII4CoII2] and [FeIII4NiII2] which originates from the ferromagnetic interactions between Fe III and M II spin centers of the square.
