A New One-Dimensional Bimetallic Complex: Cu(en)2Fe(CN)5(NO). Synthesis, Crystal Structure and Magnetic Behaviour

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...
