The title complexes, Diaquadi(2,2`-bipyridine)Di(Dichloroacetato)Lanthanide (III) Monodichloroacetato [Ln(CHCI{sub 2}COO){sub 2}(2,2`-bipy){sub 2}(H{sub 2}O){sub 2}]{sup +}(CHCI{sub 2}COO){sup -}(Ln=Dy, Ho, Tm, Er, Yb) were obtained and characterized. [Er(CHCI{sub 2}COOO){sub 2}(2,2`-bipy){sub 2} (H{sub 2}O){sub 2}]+(CHCI{sub 2}COO){sup -} crystallizes in the monoclinic space group P2{sub 1}/n with Z=4. Cell dimensions are a=15.886 (9), b=13.758(2), c=16.343(4) {angstrom}, {Beta}=113.31(3){degrees}, and the structure was refined to an R of 0.049 for 3415 observed reflections. The Er(III) ion exhibits a distorted, square antiprismatic configuration. Four N atoms of 2,2`-bipy and four O atoms from two dichloroacetato and two water ligands are coordinated. One dichloroacetato group lies outside the polyhedron and is connected with water ligands by hydrogen bonds.
