Abstract

Treatment of DyCl₃(H₂O)₆ with thionyl chloride in the presence of tetrahydrofuran provided colourless crystals of DyCl₃(THF)_3.5, subsequently identified as the ionic salt [trans-DyCl₂(THF)₅][trans-DyCl₄(THF) ₂] by an X-ray diffraction study. The dysprosium atom in the monocation is seven coordinate with the trans-DyCl₂ unit [Dy-Cl, 2.624(5) Å] surrounded by five tetrahydrofuran molecules (Dy-O, mean 2.41 (2) Å) in a regular pentagonal bipyramidal geometry. For the anion the dysprosium atom is six coordinate with an octahedral geometry comprising four equatorial chlorine atoms (Dy-Cl, mean 2.642(5) Å) and two axial tetrahydrofuran molecules (Dy-O, 2.41(2) Å).
