  A new series of discrete [(hfac)3Ln(μ-bpypz)Cr(acac)2] dinuclear complexes has demonstrated the novel LnIII ion size depedent structural transformation around LnIII as well as diastereospecifically assembled chiral configuration along with the unusual bending of the acetylacetonate chelate ring in CrIII.
