Magnetic behavior of tetrakis[4-(N-tert-butyl-N-oxylamino)pyridine]bis(isocyanato-N)cobalt(II) in frozen solution.
A complex of cobalt(II)(OCN)(2) coordinated with four pyridines having a stable tert-butyl aminoxyl exhibited in frozen MTHF a slow magnetic relaxation for the reorientation of magnetization with activation barrier, Delta/k(B) = 50 K, and a hysteresis loop having a fast relaxation at 0 Oe below 2.5 K.
