  • Homoscorpionates (hydridotris(1-pyrazoly)borato complexes) of the trivalent 4f ions: The crystal and molecular structure of (HB(N(2)C(3)H(3))(3))(3)Ln(III), (LN = Pr, Nd)


The compounds ((eta(3)-HB(N(2)C(3)H(3))(3))(3)M of scandium, yttrium, lanthanum and of the trivalent lanthanides from cerium to lutetium have been synthesized by the reaction of MCl(3) with K(HB(N(2)C(3)H(3))(3)) in tetrahydrofuran or in water. The crystal and molecular structure of the Pr and Nd compounds were determined by single-crystal X-ray diffraction. Infrared (IR) spectroscopic studies have shown that the metal ion in the LnTp(3) compounds from La to Dy is nine-coordinate, while in the compounds of the heavier lanthanides from Ho to Lu, of Sc, and Y, the central ion is eight-coordinate.
