“…This is in agreement with the fact that tetrahedral T1I4h as been found in the solution on the basis of vibrational spectra2•30 and X-ray diffraction data53 and that slightly distorted tetrahedral T1I4~h as been found in the solid state. 53,54 The correlation between the chemical shift of the metal nucleus and the geometry of the halide complexes of the d10 ions Zn2+ and Cd2+ was discussed by Maciel et al,22,24 who found that the octahedral complexes are more shielded than the complexes with tetrahedral structure. The shifts for the thallium(III) chloride and bromide complexes determined in this work make it possible to extend this discussion.…”

18-electron intermediates (e.g., HRh(P-P)(P-P)m(olefin) or HRh(P-P)(PR,)(olefin)) that have three phosphine ligands coordinated to Rh at the step in the mechanism where Rh-H addition to coordinated olefin occurs (Le., the selectivity determining step).Abstract: A combination of solution and solid-state *OST1 NMR experiments is used to study the formation and geometry of TIX,' " complexes (X = C1, Br). The chemical shifts for the individual species and their stability constants are determined for dilute (0.05 M) and concentrated (1.0 and 2.6 M) aqueous TI(II1) solutions. The existence of TIC]: -and TIC1: -as well as at least one species higher than TIBrc in solution is shown. The species TIC], is 300-400 ppm less shielded in aqueous solutions than in solid phase, indicating a structural difference. The chemical shifts obtained for the individual TIXnf" complexes are compared with corresponding shifts for zinc(I1) and cadmium(I1) halide complexes.

“…11 different structures containing the tetraiodothallate(III) anion have been reported and of these only two have the anion on a site of high crystallographic symmetry. Often the nature of the cation keeps the space-group symmetry low (Drew et al, 1970;Glaser et al, 1982Glaser et al, , 1983Beno et al, 1987;Geiser et al, 1988Geiser et al, , 1996Riera et al, 1989;Tebbe et al, 1995;Ilyukhin et al, 2000;Slavin et al, 2000), but even CsTlI 4 crystallizes in space group P2 1 /c with the anion in a general position (Thiele et al, 1986). In the salt with the Et 3 S + cation (Svensson et al, 2000), the [TlI 4 ] À anion sits on a fourfold inversion centre, but the cation is reported to be so highly disordered that the C atoms were not included in the model, thus detracting from the precision of the geometry of the anion.…”

The As and Tl atoms in title compound, (C(24)H(20)As)[TlI(4)], sit on fourfold inversion centres, resulting in a [TlI(4)](-) anion with D(2d) symmetry and a Tl-I bond length of 2.7691 (3) A. The tetrahedral anion is tetragonally distorted, being flattened in the direction of the c axis of the tetragonal unit cell, so that the two unique I-Tl-I angles differ by about 9 degrees. In contrast, the cation has S(4) symmetry and the tetrahedral coordination geometry of the As atom is very slightly stretched in the direction of the c axis.

The M-X distances, the charges on the M and X atoms and the natural electron configurations in the hypothetical MX 4 -molecules, where M is a group 13 element and X = F, Cl, Br, I, have been investigated by quantum calculations. The computed distances are compared with the experimental data, mostly in the Bu 4 N[MX 4 ] salts. We found that: (1) down group 13 both the experimental and calculated M-X distances, the charge on the M atom and the sum of the populations of the M valence orbitals show zigzag variations produced by the filled 3d and 4f shells and by the relativistic effects in the 6s and 6p 1/2 orbitals; (2) the experimental distances are shorter than the calculated values due, at least in part, to libration of the MX 4 -anions in the salts; (3) both the
