Two metal-organic coordination polymers [Cu(bpy)2(H 2O)2](NO3)2·4.5C 2H5OH (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.
Bibliographical noteFunding Information:
Two types of MOCP crystals were produced by the interaction of copper(II) nitrate, 4,4′-bipyridyl, and L-phenylalanine amino acid in an aqueous solution. The structure and composition of MOCPs were determined by single crystal X-ray diffraction. The coordination framework of [Cu(bpy)2(H2O)2](NO3)2⋅4.5C2H5OH (1) is composed of alternating cations of copper and 4,4′-bipyridyl. The framework has two types of intersecting channels of 7×7 Å and 3×7 Å. The composition of compound [Cu2(bpy)(H2O)(L-pha)2](NO3)2⋅H2O (2) involves L-phenylalanine anions and is a homochiral MOCP.
