Copper(II) glycinate refers to coordination complexes of copper(II) with the formula Cu(glycinate)₂(H₂O)_x where x = 1 or 0. It is usually isolated as the monoaquo complex (x =1), which has been characterized by X-ray crystallography. Like most amino acid complexes, the glycinate forms a 5-membered chelate ring.[1] All forms are blue, water-soluble solids. The compound has been used as a source of dietary copper in animal feeds.[2]
