Abstract

The new heteroleptic hydrotris(pyrazol-1-yl)borate lanthanide complex [Nd{HB(pz)3}2Cl] (1) was prepared from the reaction between anhydrous NdCl3and 2 equiv. of K[HB(pz)3] in THF at room temperature. The H2O adduct of 1, [Nd{HB(pz)3}2Cl(H2O)] · THF (2), is formed when a solution of 1 is allowed to stand at room temperature in the presence of moisture. Reaction of K[HB(pz*)3] with anhydrous NdCl3in the presence of 4,4′-di-tert-butyl-2,2′-bipyridine (L) yields [Nd{HB(Pz*)3}LCl2] (3) in moderate yield. All complexes have been characterized by conventional spectroscopic methods. The molecular structures of 2 and 3 have been determined by X-ray crystallography.
