摘要：

Trivalent praseodymiurn complexes with a new beta-diketiminato ligand, possessing two pendant arms, LPrX2, (X = Cl (3), Br (4), BH4 (5)), have been prepared by the reactions of the lithium salt of the ligand with the corresponding halides, X-ray structural and elemental analysis showed that 3, 4, and 5 are neutral, monomeric and solvent-free complexes. These complexes adopt a pseudo-octahedral geometry with the two X (X = Cl, Br, BH4) arranged in the trans positions. (C) 2002 Elsevier Science B.V. All rights reserved.
