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.

Green single crystals of the title compound, [Ni(N3)2(C6H6N4)2], were obtained by reacting nickel(II) perchlorate with 2,2′‐biimidazole (H2bim) and sodium azide. The azide and H2bim ligands are bonded to the Ni atom, which lies on an inversion centre, with approximately octahedral geometry. The azide anions are terminally bonded in two trans postitions. A two‐dimensional supramolecular network is formed through hydrogen bonds between ligand H2bim and azide N atoms.
