Dichloro[N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine]samarium(III) Perchlorate

The crystal structure of the title compound, [SmCl₂{C₂H₄N₂(CH₂C₅H₄N)₄}]ClO₄, at room temperature was solved and compared with the previously determined structure of [Eu^IIICl₂(R-tppn)]ClO₄ [where R-tppn is N,N,N',N'-tetrakis(2-pyridylmethyl)-(R)-propylenediamine]. The Sm³⁺ ion is eight-coordinated through the six N atoms of the N,N,N',N'-tetrakis(2-pyridylmethyl)ethylenediamine ligand and two Cl^- ions. The coordination is best described as dodecahedral with some important distortions.
