%X The nitrosyl cyanide Cu(en)2Fe(CN)5(NO) was prepared by the reaction of Cu(en)2Cl2 and Na2 &#91;Fe(CN)5(NO)&#93;.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&#8211;Teller distortion characteristic of octahedral copper complexes with bond distance deviations in lattice symmetry from octahedral ideality: Cu-N(equatorial, mean) 2&#183;010(3) &#197; and Cu-N(axial, mean) 2&#183;569(3) &#197;. Infrared and ultraviolet studies shed light on the above molecular structure. A magnetic investigation showed the presence of a weak antiferromagnetic interaction (J = -1&#183;06 cm-1) between the copper atoms within each chain through the diamagnetic Fe(CN)5(NO)2- ions.
