The self‐assembly reaction of [Cr(CN) 6 ] 3– , Ln 3+ , and a chelated phen ligand resulted in the first examples of cyano‐bridged 3d‐4f helical chains [Ln(phen) 3 (H 2 O)][Cr(CN) 6 ] · 3H 2 O [Ln = La ( 1 ), Ce ( 2 ), Pr ( 3 ) and Nd ( 4 )], in which the lanthanide center was coordinated unusually by three molecules of a bidentate ligand. The magnetic properties of compounds 2 – 4 were also investigated.
