Abstract: A conformationally flexible ligand, [(Flu)-(CH2)2-(NHC)-CH2-(NHC)-(CH2)2-(Flu)]2- (L), that offers four sequential organic donor modules and enwraps a Ca2+ pseudo-tetrahedrally in a twisted 'S'-shape is devised. The [(L)Ca] synthesis is intriguingly stepwise involving the intermediate [(LH)Ca(HMDS)], whereas… read more here.
