Article abstract of DOI:10.1016/0022-328X(88)89021-1

The preparation of cis- (biL denotes 2,2'-bipyridine-x,x'-dicarbonitrile, x,x'=4,5) is reported.Reaction of these complexes with produces .The synthesis of (biL, x,x'=5) is also reported.The ligands and complexes have characterised by spectroscopy (IR, electronic absorption, NMR) and microanalysis.The synthesis of biL is significantly assited by ultrasonication.
