      The first examples of cyano-bridged 3d-4f compounds with a helical chain structure were obtained by the self-assembly of hexacyanometalate, lanthanide ions, and a phen ligand. In the structure, the lanthanide atoms were coordinated unusually by three molecules of a bidentate ligand. The presence of the chelated phen ligand played an important role in the formation of these achiral helical chains.
