A mononuclear Co(ii) complex formed from pyridinedimethanol with manifold slow relaxation channels†
Abstract
A mononuclear hexacoordinate complex [Co(pydm)2](dnbz)2 formed from 2,6-pyridinedimethanol in the coordination sphere of Co(II) and dinitrobenzoato anions exhibits magnetic anisotropy of an easy axis type and a field induced slow magnetic relaxation with manifold relaxation channels. The low-frequency relaxation time is as slow as τLF = 0.13 s at BDC = 0.4 T and T = 1.9 K.
