  5-dithiolate) gave the neutral dithiolene compounds [U(COT)(dithiolene)]2 in good yields (dithiolene = dddt, dmio, or 1,3-dithiole-4,5-dithiolate (mdt)). The X-ray crystal structures of [U(COT)(mdt)]2 and [U(COT)(mdt)(pyridine)2] show the interaction between the CC double bond of the mdt ligand and the uranium atom, and the 1H NMR spectra reveal the facile dithiolene ring inversion process in solution

  Reaction of [K(Et(2)O)][SPS(Me)] with [U(Cp*)(BH(4))(3)] or [U(COT)(BH(4))(2)(THF)] in THF gave the expected substitution products [U(Cp*)(BH(4))(2)(SPS(Me))] (1) and [U(COT)(BH(4))(SPS(Me))] (2), respectively. Protonolysis of 2 with [NEt(3)H][BPh(4)] afforded the cationic complex [U(COT)(SPS(Me))(NEt(3))][BPh(4)] (3), which was transformed into [U(COT)(SPS(Me))(L)][BPh(4)] [L = OPPh(3) (4) or HMPA (5)]. Changing [K(Et(2)O)][SPS(Me)] with [Na][SPS(OMe)] in its reaction with [U(COT)(BH(4))(2)(THF)] afforded a mixture of complexes, among which [U(COT)(BH(4))(SPS(H))] (6) was deposited as red crystals of a THF solvate. Complex 6 was isolated in 79% yield from the reaction of [U(COT)(BH(4))(2)(THF)] and SPS in the presence of a catalytic amount of NaBH(4); the key intermediate of the reaction is [Na(THF)(x)][SPS(H) center dot BH(3)], formed by addition of NaBH4 to SPS, which reacts with [U(COT)(BH(4))(2)(THF)] to give 6 and NaBH(4). The X-ray crystal structures of 1 . 4.5C(6)H(12), 2 . THF, 5 . Et(2)O, and 6 . 1.5THF indicate that the central moiety of the SPS ligand can be considered as a classical phosphine, the anionic charge being stabilized by delocalization over the five carbon atoms of the phosphahexadienyl anion and negative hyperconjugation into the two Ph(2)PS pendant arms. The X-ray crystal structures of [U(COT)(S(2)PPh(2))(mu-OMe)}(2)] and [U(COT)}(4)U(THF)(3)}(2)(mu(3)-S)(8)], which resulted from decomposition of the SPS ligand, are also presented.
