Abstract

ErCl3(thf)3.5 has been identified by an X-ray diffraction study as the ionic salt [trans-ErCl2(thf)5][trans-ErCl4(thf) 2]. The monocation features a seven-coordinate erbium atom with a trans-ErCl2 unit (Er-Cl, 2.563(2) Å) surrounded by five tetrahydrofuran molecules (Er-O, in the range 2.383(8)-2.393(8) Å) in a regular pentagonal bipyramidal geometry. The anion is six-coordinate with an octahedral metal geometry comprising four equatorial chlorine atoms (Er-Cl, 2.593(3) and 2.609(3) Å) and two axial tetrahydrofuran molecules (Er-O, 2.313(9) Å).
