Thermal- or photodecomposition of classical free radical generating diazo reagent 2,2'-azobis(2-methylpropionitrile) (AIBN) was used as the source of cyanide anions in the synthesis of copper(I)-cyanide frameworks.  The reported methodology utilized direct reduction of CuII(aa)(NN)X (aa=deprotonated amino acid, NN=bidentate nitrogen based ligand, X=Cl or Br) complexes by AIBN/ascorbic acid to yield eight novel coordination networks.  Aromatic amines were directly incorporated into one-dimensional CuI-CN chains.  In the case of aliphatic amine tetramethylethylenediamine, porous three-dimensional CuI-CN framework was obtained.  This novel procedure is mild, applicable to a variety of nitrogen based ligands, and represents an efficient and green alternative to currently used hydrothermal or solvothermal methods.
