Abstract

Complexes of the type UCl2 - x(OR)x(HBPz3)2(Pz ≡ pyrazolyl; x = 1 or 2; R ≡ CH3, C2H5, C6H5, C6H2-2,3,5-Me3) were prepared and characterized. The room temperature1H-NMR spectra of these complexes indicated that they have equivalent pyrazolyl rings, thus showing fluxional behaviour. The dynamic process can be slowed at low temperatures but the activation energy for the rearrangement is smaller than for the related complexes UCl2 - x(X)x(HBPz3)2(x = 1: X = NEt2, NPh2, 3,5-Me2Pz; x = 2: X ≡ SPr1, SBut; x = 1, 2: X = OBut, OPri, OC6H2-2,4,6-Me3). The structures of theeight-coordinate complexes UCl(OC6H5)(HBPz3)2and of the previously reported UCl(OBut)(HBPz3)2were determined by single crystal X-ray diffraction and are discussed. © 1989.
