Synthesis and magnetism of multi-dimensional cyanide-bridged bimetallic assemblies

Synthesis, spectroscopic characterization, X-ray structure, and DFT calculations of [Cu(tppz)(SCN)2]

“…They can act as monodentate ligands and as bridging ligands leading to the formation of mononuclear and polynuclear species with different dimensionality and nuclearity. Among these, the azide-and thiocyanatecontaining metal complexes are considered to be the most investigated systems because of their diverse structures and applications in magnetic materials [1][2][3][4][5][6][7]. It has been widely reported that the EO bridging mode generally mediates ferromagnetic coupling, while the EE does antiferromagnetic coupling.…”

A Spin Crossover Transition in a Mn(II) Chain Compound

“…In these very few examples of LS Mn(II) complexes, the metal is surrounded by a N-rich chromophore with N atoms mainly arising from cyano or oxime groups. Examples of chromophores include N3O3 [33], N4S2 [34], N4O2 [35] and N6 [36][37][38][39], including six -CN groups [40,41]. The assignation of the LS centers to the anionic chain (where Mn1 is surrounded by four -CN groups from four tcnopr3OH´ligands) is straightforward, since the ligand field of these -CN groups is expected to be much larger than the one created by the four water molecules coordinated to Mn2 in the cationic chain.…”

Influence of Water Molecules on Properties of Binuclear or Bridged Structures for Chiral CuII-NiII, CuII-PdII, and CuII-PtIITetracyano-Bimetallic Assemblies

“…In recent years, cyanide-bridged coordination polymers [1,2] and their various functions and multifunctions such as photomagnets [3][4][5][6][7] and chiral magnets [8][9][10][11][12][13][14], including N,N'-dimethyl-cyclohexane-1,2-diamine ligands [14], have been studied vigorously. From the viewpoint of crystal engineering, structural dimensionality, flexibility (static structural strain and dynamic structural changes by external physical stimulus), and tuning of electronic properties by these factors are important things for rational design of functional materials.…”
