Synthesis, Structure and Properties of a Trinuclear μ‐Cyano Tetracyanodinitrosylferrate Copper Complex

Abstract

Nitroprusside reacts with [Cu(dohpn)(H2O)]ClO4 (dohpn = 2,3,9,10‐tetramethyl‐1,4,8,11‐tetraazaundecane‐1,3,8,10‐tetraen‐11‐ol‐1‐olate) in methanol to produce the title complex. Single‐crystal structure analysis shows a neutral discrete trinuclear molecule containing two [Cu(dohpn)]+ units linked by one [Fe(CN)4(NO)2]2− anion through bridging‐cyanide ligands. Mössbauer data and magnetic measurements are consistent with a low‐spin iron(II) configuration. The observed paramagnetic behavior is in quantitative agreement with two isolated copper(II) (S = 1/2) sites with a very weak antiferromagnetic interaction.

Supramolecular assembly of new heteropolymetalic molecules based on tetraiminodiphenolate macrocycle and hexacyanometallate anions: Magnetostructural and spectroscopic properties

“…These building blocks combined with coordinatively unsaturated systems, like cationic Schiff-bases, produce 1D, 2D or 3D network structures. These assemblies also called Prussian blue analogues gained importance due to the innumerous possibilities to prepare novel extended lattices [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22].…”

Synthesis, crystal structure and properties of the cyano-bridged heteropolynuclear [Cu(meso)]3[Co(CN)6]2•9.5H2O compound

“…[1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] These building blocks, combined with coordinatively unsaturared systems such as cationic Schiff-bases, produce 1D, 2D or 3D network structures. These assemblies, also called Prussian blue analogues, gained importance due to the innumerous possibilities to prepare novel bimetallic extended lattices.…”
