Reaction of LnCl3 with Na2(PDDA) (PDDA = phenylene-1,2-dioxydiacetate) in a 1 to 2 mol ratio in aqueous solution yielded [Ln2(PDDA)3(H2O)6]¡¤2H2O, structurally characterized for Ln = Ce (1), Sm (2) (redetn.), Tb (3) and Y (4) in a monoclinic C2/c array, a second related structural form [orthorhombic, Pbcn] being obtained for Tb (5), Ho (6) and Er (7). The ‘domains of existence’ of these two previously described forms are now extended to Ce-Dy, Y, and Eu-Er, resp. Reaction under the same conditions for the heavier Yb3+ ion yielded [Yb2(PDDA)3(H2O)6](¡Þ|¡Þ)¡¤4H2O (8), orthorhombic, Pbca. In the case of Ln = La the bimetallic species [NaLa(PDDA)2(H2O)2](¡Þ|¡Þ)¡¤4H2O (9) was obtained, while reaction of LnCl3 with Na2(PDDA) in a 1 to 3 mol ratio led to the isolation of the isotypic (monoclinic, P21/c) [NaLn(PDDA)2(H2O)2](¡Þ|¡Þ)¡¤4H2O for Ln = Ce (10) and Sm (12). With the smaller Ln = Yb, the more definitively bimetallic [NaYb(PDDA)2(H2O)2](¡Þ|¡Þ)¡¤3H2O (13) (triclinic, P1?) was obtained, the trihydrate solvation ascribed differing from that recorded (dihydrate) in a cosynchronous report.
