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.
