Abstract

A 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.
