Rigid 1D Coordination Polymers with Tunable Metal Cation and Chiral Pendant Moieties

Abstract

AbstractA series of homochiral chain coordination polymers, based on structurally robust 4,4′‐bipyridyl (bpy) linker with tunable 3d metal cations (Co2+, Ni2+, Cu2+, Zn2+) and chiral auxiliary ligands (R‐3‐chloromandelate, S‐3‐phenyllactate, and S‐3,3‐dimethyllactate) were synthesized and characterized by X‐ray crystallography. Complexes with chloromandelate and dimethyllactate ligands are the first structurally characterized coordination compounds of such chiral molecules. All the compounds are based on robust chain motifs {M(bpy)}∞, decorated with chiral acid residues and other ligands. One structure represents a rare example of a triple‐chained ribbon (double ladder), while five others are nearly isostructural, featuring rigid metal‐organic chains, decorated by chiral pendant ligands.
