Abstract

Treatment of GdCl3(THF)(2) with an acetonitrile solution of antimony(V) chloride (as halide abstractor) in the presence of dibenzo-18-crown-6 provides the yellow crystalline salt [GdCl2(dibenzo-18-crown-6)(MeCN)][SbCl6].2MeCN whose structure has been determined by single-crystal X-ray diffraction. The gadolinium atom is situated within the ring cavity, bonded to all six oxygen atoms of the oxacrown, Gd-O 2.545(4)-2.683(4) Angstrom. Further bonding to two chlorine atoms, located on opposite sides of the ring plane, Gd-Cl 2.632(2), 2.679(2) Angstrom, and one acetonitrile molecule, Gd-N 2.579(5) Angstrom, gives a nine-coordinate cation geometry approximating a planar hexagon with two capping atoms above and one below the plane.
