Abstract. Let 𝘎 be a real semisimple algebraic Lie group and 𝘏 a real reductive algebraic subgroup. We describe the pairs (𝘎,𝘏) for which the representation of 𝘎 in L²(𝘎/𝘏) is tempered. The proof gives the complete list of pairs (𝘎,𝘏) for which L²(𝘎/𝘏) is not tempered. When 𝘎 and 𝘏 are complex Lie groups, the temperedness condition is characterized by the fact that 𝘵𝘩𝘦 𝘴𝘵𝘢𝘣𝘪𝘭𝘪𝘻𝘦𝘳 𝘪𝘯 𝘏 𝘰𝘧 𝘢 𝘨𝘦𝘯𝘦𝘳𝘪𝘤 𝘱𝘰𝘪𝘯𝘵 𝘰𝘯 𝘎/𝘏 𝘪𝘴 𝘷𝘪𝘳𝘵𝘶𝘢𝘭𝘭𝘺 𝘢𝘣𝘦𝘭𝘪𝘢𝘯.

New coordination environments are reported for Np( iii ) and Pu( iii ) based on pilot studies of U( iii ) in 2.2.2-cryptand (crypt). The U( iii )-in-crypt complex, [U(crypt)I 2 ][I], obtained from the reaction between UI 3 and crypt, is treated with Me 3 SiOTf (OTf = O 3 SCF 3 ) in benzene to form the [U(crypt)(OTf) 2 ][OTf] complex. Similarly, the isomorphous Np( iii ) and Pu( iii ) complexes were obtained similarly starting from [AnI 3 (THF) 4 ]. All three complexes (1-An; An = U, Np, Pu) contain an encapsulated actinide in a THF-soluble complex. Absorption spectroscopy and DFT calculations are consistent with 5f 3 U( iii ), 5f 4 Np( iii ), and 5f 5 Pu( iii ) electron configurations.more » « less
