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 com-plex is triclinic with space group P1, formula C30H66O42N6Cl6ErY, Mr,= 1651. 76, a=9. 860(2), b=13. 020(5), c= 13. 632(5) A ; a= 109. 32(3), β=110. 19(2), γ=100. 96(2)°, V= 1456(1 ) A3, Dc= 1. 884 g/cm3, Z= 1, F(000) =833, P= 2. 812mm-1 ;R=0. 046, wR(F2) =0. 123 for 4897 reflections with I>2(I). The complexis 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=1/2(Er+Y).
