Synthesis and crystal structure of a heteronuclear copper and yttrium complex with alanine: [CuY(Ala)₄(H₂O)₅](ClO₄) ₅·3H₂O

The title complex was synthesized in aqueous solution and its crystal structure was determined by X-ray diffraction. The complex is binuclear, with copper and yttrium ions connected by four bridging carboxyl groups from four alanine molecules. The yttrium ion is coordinated by four oxygen atoms from four carboxyl groups and four oxygen atoms of four water molecules with the coordination number eight, taking a square antiprism arrangement.
