Abstract

Two phenoxo- and cyanido-bridged one-dimensional complexes Ni^II₂Gd^III₂Fe^III₃ (1) and Ni^II₂Dy^III₂Fe^III₃ (2) have been prepared. They are the first pentacyanidoferrite-bridged heterotrimetallic complexes. Magnetic studies reveal that overall ferromagnetic interactions are present in complexes 1 and 2, and complex 2 shows single-molecule magnet (SMM) behaviour with an energy barrier of 14.8 K.
