The title complex was synthesized in an aqueous solution at pH≃3. 5, and its crystal structure was determined by X-ray diffraction methods. The complex is triclinic with space group P1, formula C 30H 66O 42N 6Cl 6ErY, M r= 1651. 76, a9.860(2), b=13. 020 (5), c=13. 632(5) Å ; α=109. 32(3), β= 110. 19(2), γ=. 100. 96(2)° V=1456(1) Å 3, Å= 3,D c = 1. 884 g/cm 3, Z = l, F(000) = 833, μ = 2. 812 mm -1; R=0. 046, wR(.F 2)= 0.123 for 4897 reflections with I>2σ(I). The complex is of an infinite chain structure with the neibouring metal ions connected by two bridging carboxyl groups from two different proline molecules. The erbium ion and the yttrium ion statistically lies at the position of the metal ion with M=l/2(Er+Y).
