H2peha2+ ion, the complex cation [Ln2(μ-OH)2(tepa)2Cl2]2+, a [Ge2Se6]4– anion, free Cl– ions, and a [Ln2(μ-OH)2(tepa)2Cl]2(μ-Ge2Se6)}2+ cation constructed by two unsaturated [Ln2(μ-OH)2(tepa)2Cl]3+ groups connecting via the trans terminal Se atoms of the [Ge2Se6]4– anion, which provides the first example of an organic decorated lanthanide selenidogermanate cation. Both compounds 2 and 3 contain one-dimensional
