• Uranium(VI) Sulfilimine Complexes:  A New Class of Nitrogen Analogues of the Uranyl Ion

  The compound tetraphenylphosphonium tetrachlorooxo-S,S-diphenylsulfiliminatour [Ph4P][UOCl4(NSPh2)], has been prepared in high yield from [Ph4P][UOCI5] and [Ph2S=NSiMe3]. An X-ray structure of this compound shows that the uranium atom has a pseudooctahedral geometry with oxygen and nitrogen atoms in trans positions. The structure of the analogous phosphoriminato complex [Ph4P][UOCl4(NPPh3)] has been determined for comparison. Derivatization of the sulfide group shows that only a limited range of functionalization confers stability toward reduction. The emission spectrum of the first electronic excited state reveals a greatly reduced energy compared with that of the uranyl ion. This red shift in the transition is consistent with the weakening of the U-N bond relative to the U-O bond.

  Crystals of the title compound, (C24H2OP)(2)[UO2Cl4].-CH2Cl2, contain pseudo-octahedral tetrachlorouranyl anions having approximate D-4h and exact C-i point symmetry. The asymmetric unit contains two such anions, each distinct and isolated, and each unperturbed by close anion-anion packing, hydrogen bonding or the presence of small polarizing cations. The U=O bond lengths are 1.75 (1) and 1.77 (1) Angstrom, and provide points of reference for the recently reported oxouranium (phosphorane iminato) complex containing the O-U=N- group.

  A series of compounds containing the -N=U=N- group has been prepared. Their physical and chemical properties are reported. They adopt a trans configuration, and are thermally robust. The chemistry of some recently-prepared O=U=N- compounds is also described. These are the first examples of stable analogs of the uranyl ion UO22+. The factors that determine their stability are discussed.
