Abstract

Two metal-organic coordination polymers [Cu(bpy)2(H2O)2](NO3)2·4.5C2H5OH (1) and [Cu2(bpy)(H2O)(L-pha)2](NO3)2·H2O (2) (L-Hpha = L-phenylalanine, bpy = 4,4′-bipyridyl) are prepared by slow evaporation of an aqueous alcoholic solution of copper nitrate, L-phenylalanine, and 4,4′- bipyridyl. The structure and composition of the obtained compounds are determined by single crystal XRD. The framework of compound 1 is positively charged and forms two types of intersecting channels. Compound 2 is a homochiral metal-organic coordination polymer whose structure contains L-phenylalanine anions.
