Exceptionally slow magnetic relaxation in a mononuclear hexacoordinate Ni(ii) complex†
Abstract
A hexacoordinate mononuclear [Ni(pydm)2](dnbz)2 complex shows field-induced slow magnetic relaxation with two or three relaxation channels that are strongly supported by an external magnetic field. At BDC = 0.8 T and T = 1.9 K, the low-frequency (LF) relaxation time is as slow as τ(LF) = 1.3 s with the mole fraction of x(LF) = 0.47.
