Magnetic Anisotropy and Field-induced Slow Relaxation of Magnetization in Tetracoordinate Co-II Compound [Co(CH3-im)(2)Cl-2]
Original language description
Static and dynamic magnetic properties of the tetracoordinate Co-II complex [Co(CH3-im)(2)Cl-2], ( 1, CH3-im = N-methyl-imidazole), studied using thorough analyses of magnetometry, and High-Frequency and -Field EPR (HFEPR) measurements, are reported. The study was supported by ab initio complete active space self-consistent field (CASSCF) calculations. It has been revealed that 1 possesses a large magnetic anisotropy with a large rhombicity (magnetometry: D = -13.5 cm(-1), E/D = 0.33; HFEPR: D = 14.5(1) cm(-1), E/D = 0.16(1)). These experimental results agree well with the theoretical calculations (D = -11.2 cm(-1), E/D = 0.18). Furthermore, it has been revealed that 1 behaves as a field-induced single-ion magnet with a relatively large spin-reversal barrier (U-eff = 33.5 K). The influence of the Cl-Co-Cl angle on magnetic anisotropy parameters was evaluated using the CASSCF calculations.
