Abstract
Reaction of U(BH4)4 with K[tmp](tmp = 2,3,4,5-tetramethylphospholyl) afforded the uranium(IV) complexes [U(tmp)(BH4)3] and [U(tmp)2(BH4)2]. Sodium amalgam reduction of these complexes in tetrahydrofuran gave the uranate(III) anions [U(tmp)(BH4)3]– and [U(tmp)2(BH4)2]– which were alternatively obtained by treating [U(C6H3Me3-1,3,5)(BH4)3] with K[tmp]. Similar reactions in toluene led to the formation of the neutral compound [{U(tmp)2(BH4)}2]. The fluxionality and the stability of the complexes are described.Keywords
