摘要

Two one-dimensional (1D) cyanide- and phenolate-bridged heterotrimetallic complexes {[Cu~(II)Mn~(II)(L!1)][Fe ~(III)(bpb)(CN)_2]}_n?(ClO_4) _n?(H_2O)_n (1) and {[Cu~(II)Mn ~(II)(L~1)][Cr~(III)(bpb)(CN)_2]} _n?(ClO_4)_n?(H_2O) _n (2) (bpb~(2-) = 1,2-Bis(pyridine-2-carboxamido)benzenate) have been designed and prepared based on cyanide-containing building blocks K[M(bpb)(CN)_2] [M = Fe(III) and Cr(III)] together with compartmental macrocyclic Schiff-base complex [CuMn(L1)]?(ClO _4)_2, in which H_2L~1 is derived from 2,6-diformyl-4-methyl-phenol, ethylenediamine, and diethylenetriamine. Investigation of their magnetic properties reveals the overall antiferromagnetic behavior of these two complexes. These results seem to represent the first example of 1D infinite cyanide- and phenolate-bridged single chain-like compounds containing three kinds of spin carriers 3d-3d′-3d″prepared by a stepwise method.
