Synthesis and Characterization of Homo- and Heteroleptic Neptunium(IV) Heteroarylalkenolate Complexes.

ABSTRACT: Heteroleptic An^IV (An = U, Np) chlorido-ketoenaminate complexes of the type [AnCl₂(TFB-tBuA)₂(THF)] (An-1 type: U-1, Np-1; TFB-tBuA = 4-(tert-butylamino)-1,1,1-trifluorobut-3-en-2-one) and the homoleptic Np^IV heteroarylalkenolate complexes [Np(PyTFP)₄] (Np-2, PyTFP = 1-(pyridin-2-yl)-3,3,3-trifluoroprop-1-en-2-ol) and [Np(DMOTFP)₄] (Np-3, DMOTFP = 1-(4,5-dimethyloxazol-2-yl)-3,3,3-trifluoroprop-1-en-2-ol) were synthesized and characterized (SC-XRD, NMR, Vis-NIR, MS). While their solid-state structures compare well to those of their uranium analogues, the behavior in solution showed significant differences. The binding motif of the DMOTFP ligand in complex Np-3 ca
