Abstract:
The nitrosyl cyanide
Cu(en)2Fe(CN)5(NO) was prepared by the reaction of Cu(en)2Cl2 and
Na2 [Fe(CN)5(NO)].2H2O in aqueous solution. Single-crystal X-ray structure analysis revealed that the
complex assumes a cyanide-bridged chain structure in which iron(II) is coordinated by five cyanide ligands and a nitrosyl group, and copper(II) is
coordinated by two ethylenediamine ligands and two bridging cyanide ligands. The copper centres display a typical Jahn–Teller distortion
characteristic of octahedral copper complexes with bond distance deviations in lattice symmetry from octahedral ideality: Cu-N(equatorial, mean)
2·010(3) Å and Cu-N(axial, mean) 2·569(3) Å. Infrared and ultraviolet studies shed light on the above molecular structure.
A magnetic investigation showed the presence of a weak antiferromagnetic interaction (J = -1·06
cm-1) between the copper atoms within each chain through the diamagnetic Fe(CN)5(NO)2-
ions.
