The absorption spectra of 4f electron transItIons of complexes of ferron (5-sulpho-7-mdoqumohn-8-01) with neodymmm and e&mm m the presence. of dlethylamme were measured Their molar absorptMy at the manmum absorption bands was about 7 5 (at 574 2 nm) times greater for neodymmm and 10 8 (at 519 8 nm)
## Abstract Reaction of UCl~4~ with [Li{RC(NCy)~2~}(THF)]~2~ (R = Me, 1a; R = __n__Bu, 1b) in THF gave the tris(amidinate) compounds [U{RC(NCy)~2~}~3~Cl] (R = Me, 2a; R = __n__Bu, 2b) which were reduced with lithium powder in THF to the homoleptic complexes [U{RC(NCy)~2~}~3~] (R = Me, 3a; R = __n__
Bis(pentafluorophenyl)cadmium, [Cd(C 6 F 5 ) 2 ], reacts with equimolar amounts of triphenylmethanethiol, TrtSH, in toluene to give [{Cd(C 6 F 5 )(STrt)} 4 ] ΠΈ 1.5 tol (1). The cuboidal complex of 1 has been transformed into the heterometallic cuboidal complex [{Cd(C 6 F 5 )(STrt)} 3 (OH)K(THF) 3 ]
