Novel structural transformation around Ln(III) and unusual bending of acetylacetonato chelate in a series of new 3d-4f dinuclear complexes [(hfac)3Ln(μ-bpypz)Cr(acac)2]

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