Magnetostructural Correlations in CuII−NC−WV Linkage: The Case of [CuII(diimine)]2+−[WV(CN)8]3− 0D Assemblies

“…In this context, cyano-bridged Cu(II)-octacyanometalate(V,IV) (M ) Mo, W) assemblies are among the most extensively studied systems. [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] The dynamic research activity in this field resulted in construction of the heterobimetallic clusters and extended networks. The majority of cyano-bridged Cu II -NC-W V systems display dominant ferromagnetic coupling between metal centers, which is usually accompanied by much weaker intra-or intermolecular antiferromagnetic coupling, [10][11][12][13][14][15][16][17][18][19][20][21] leading to metamagnetism in some cases.…”

“…decane), although the trinuclear Cu 2 W unit shows a Cu-W-Cu angle close to 90°. 24 The discussion of the magnetic behavior and the correlation of the J CuW parameters with the geometry of cyano bridges at copper(II) centers of 1 and 2 is based on DFT calculations.…”

Cyanide-Bridged Mn(III)−Fe(III) Bimetallic Complexes Based on the Pentacyano(1-methylimidazole)ferrate(III) Building Block: Structure and Magnetic Characterizations

“…During the past decades, more and more attention has been paid to the research of cyanide-bridged complexes because of their remarkable magnetic, magneto-optical, and electrochemical properties. − Several different approaches have been employed to design molecule-based magnets that exhibit spontaneous magnetization. Many Prussian blue analogues M x [M‘(CN) 6 ] y · n H 2 O have been synthesized by the reaction of cyanide-containing building blocks [M‘(CN) 6 ] 3- (M‘ = Fe, Cr, Mn) with other paramagnetic metallic complexes [M(H 2 O) 6 ] m + , and some of them exhibit long-range magnetic ordering at considerably high temperatures …”
