Preparation and Crystal Structure of (4-Picolinium)[LnCl4(H2O)3] (Ln = La, Ce, Pr, Nd)The complex water containing chlorides (4-Picolinium)[LnCl4(H2O)3] (Ln = La, Ce, Pr, Nd) were prepared for the first time, and the crystal structures of (4-Picolinium)[LnCl4(H2O)3] (Ln = La, Pr) were determined on single crystals by X-ray methods. The isotypic compounds crystallize with triclinic symmetry, space group P1, Z = 2. Surprisingly there exist the dimeric complex anions [Ln2Cl8(H2O)6]2- (Ln = La, Pr).
Notes:
Die komplexen wasserhaltigen Chloride (4-Picolinium)[LnCl4(H2O)3] (Ln = La, Ce, Pr, Nd) wurden erstmals dargestellt und die Kristallstrukturen von (4-Picolinium)[LnCl4(H2O)3] (Ln = La, Pr) anhand von Einkristalluntersuchungen röntgenographisch bestimmt. Die isotypen Verbindungen kristallisieren in der triklinen Raumgruppe P1, Z = 2. überraschend liegen die dimeren komplexen Anionen [Ln2Cl8(H2O)6]2- (Ln = La, Pr) vor.
