Abstract
The complex water containing chlorides (4-Picolinium)2LnCl4(H2O)3!Cl (Ln = Eu, Ho) were prepared for the first time. The crystal structures were determined on single crystals by X-ray methods. The isotypic com pounds crystallize with triclinic symmetry, space group P1BAR, Z = 2. Surprisingly the structures contain the complex anions LnCl4(H2O)3!- (Ln = Eu, Ho) where the ligands form a distorted pentagonal bipyramid, which to our knowledge has not been observed in lanthanide compounds till now.
