摘要

A mononuclear Ni(ii) complex, [Ni(pydca)(dmpy)]H2O, pyridine-2,6-dicarboxylato-2,6-dimethanolpyridine nickel(ii) monohydrate, exhibits a slow magnetic relaxation under an applied magnetic field with two and/or three relaxation channels. While at B-DC = 0.2 T, the low-frequency relaxation mode is weakly developed, its intensity grows rapidly with the field so that at B-DC = 0.6 T, this is the dominating relaxation path giving rise to a relaxation time of (LF) = 322 ms at T = 2.0 K. At B-DC = 1.2 T the relaxation time is as slow as (LF) = 876 ms.
