Abstract
Two one-dimensional (1D) cyanide- and phenolate-bridged heterotrimetallic complexes {[CuIIMnII(L1)][FeIII(bpb)(CN)2]}n·(ClO4)n·(H2O)n (1) and {[CuIIMnII(L1)][CrIII(bpb)(CN)2]}n·(ClO4)n·(H2O)n (2) (bpb2− = 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)]·(ClO4)2, in which H2L1 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.
