Abstract
Treatment of U(NEt2)4 with PhSH gave [NEt2H2]2[U(SPh)6]1, Reaction of UCl4 with NaSPh in the presence of CuSPh and PPh3 afforded [(Ph3P)Cu(µ-SPh)3U(µ-SPh)3Cu(PPh3)]2. The geometrical parameters of the octahedral US6 core are quite similar in the crystal structures of 1, 2·6thf and [(thf)3Na(µ-SPh)3U(µ-SPh)3Na(thf)3](thf = tetrahydrofuran). The U–Cu distance of 3.05(1)A supports the presence of a direct metal–metal interaction.
