Optical Absorption and X-Ray Photoelectron Spectroscopic Studies of Thorium Tetrabromide
Allen, Geoffrey C.,Hubert, Solange,Simoni, Eric
, p. 2767 - 2770 (1995)
Optical absorption and X-ray photoelectron spectroscopies have been used to investigate the electronic structure of ThBr4 in relation to ThF4 and ThCl4.The same electronic process appears to be responsible for the Th 4f photoelectron 'shake-up' satellites

The interaction of thorium(IV) salts with 4[N-(benzylidene)amino]antipyrine semicarbazone (BAAPS), 4[N-(4′-methoxybenzylidene)amino] antipyrine semicarbazone (MBAAPS), 4[N-(4′-dimethoxyaminobenzylidene)amino]antipyrine semicarbazone (DABAAPS), 4[N-(2′-nitrobenzylidene)amino]antipyrine semicarbazone (2′-NO2BAAPS), and 4[N-(3′- nitrobenzylidene)amino]antipyrine semicarbazone (3′-NO2BAAPS) in non-aqueous solvents resulted in the formation of [ThL2X 4] (X = Cl, Br, or NCS), [ThL2I2]I2, [ThL2](ClO4)2 or [ThL(NO3) 4] (L = BAAPS, MBAAPS, DABAAPS, 2-NO2BAAPS, or 3-NO 2BAAPS). All of these compounds were characterized by elemental analyses, electrical conductivity, IR, and thermal methods. X-ray powder diffraction studies of a representative complex were also undertaken. Th(IV) displays the coordination numbers 6, 8, 10, and 11 in these compounds depending on the nature of the coordinated anion and the stoichiometry.
Studies on ABX6 Compounds. II[1] The BaThBr6 Structure Type
Beck, H. P.,Kuehn, F.
, (2008/10/08)
The compounds AThBr6 (A:Ca, Sr, Ba) crystallize in an ordered substitution variant of the PuBr3 type. Their syntheses and special features of the crystal structures are described.
