AB Different novel coordination polymers containing zinc, 1–4, and copper, 5–8, metals, connected viachiral imidazolium-based dicarboxylate ligands, [LR]−, were isolated by reaction between zinc acetate orcopper acetate and enantiomerically pure HLR compounds. They were characterised and structurallyidentified by X-ray diffraction methods (single crystal and powder). These compounds are twodimensionalhomochiral coordination polymers, [M(LR)2]n, in which the metal ions are coordinated by thetwo carboxylate groups of [LR]− anions in a general bridging monodentate μ2–κ1-O1,κ1-O3 fashion thatafforded tetrahedral metal coordination environments for zinc, 1–4, and square planar for copper, 5–8,complexes. In all the compounds the 3D supramolecular architecture is constructed by non-covalentinteractions between the hydrophobic parts (R groups) of the homochiral 2D coordination polymers and,in some cases, by weak C–H⋯O non-classical hydrogen bonds that provided, in general, a dense crystalpacking. DFT calculations on the [LR]− anions confirmed their conformational flexibility as ditopic linkersand this fact makes possible the formation of different coordination polymers for four-coordinated metalcenters. Preliminary studies on the Zn-catalyzed synthesis of chiral α-aminophosphonates were carriedout and, unfortunately, no enantioselectivity was observed in these reactions.
