“…The metal atom is also bound to the oxygen atom of a neighbouring (Fig. The Tl-S(1) distance is shorter than that found in diorganothallium(lll) complexes with S,S'ligands, such as dithiophosphinate [14][15][16], phosphinodithioformate [17], xanthate [18] and tetraphenyldithioiminodiphosphinate [19]; and is slightly longer than the mean Tl-S distance in diorganothallium (III) dithiocarbamates [20,21 ]. This polymer structure is reinforced by weak TI...S interactions (Tl-S(1)' = 3.315(3) Ä, sum of Van der Waals radii 3.75 Ä [13]).…”

“…The main distorted angles are C(1)-TI-C(2) (162.5(4)°) and S(1)-TI-0(1) (57.0(2)°), the value of the latter being imposed by the bite of the ligand. In the mtc complex the weak inter-unit TI...S interactions possibly hinder ring coplanarity due to the habitual preference of the sulphur atom for pyramidal coordination [12,20], The Tl-0(1) distance is longer than the intra-unit TI-0 distances found in other thallium (III) complexes with anionic 0,X ligands, such as acetate, tropolonate, acetylacetonate (X= 0) [22] and 1 -oxidopyridinium-2-thiolate (X= S) [11], but in all these complexes except the acetate there is also a longer inter-unit TI-0 distance, and the TI-O-TI bridges in these compounds are in fact more asymmetrical than in [TIMe 2 {S(0)CNEt 2 }].…”

DimethyKdiethylmonothiocarbamato)thallium(IM), [TIMe 2 {S(0)CNEt 2 }] was synthesized by reacting TIMe 2 (N0 3 ) and [Et 2 NH 2 ][S(0)CNEt 2 ] in ethanol. The compound crystallized in the monoclinic space group P2,/n (No. 14) with a= 7.3379(4), b= 8.030(1), c= 19.032(3) Ä and β= 100.611(8)°, V= 1102.2(2) Ä 3 and Z= 4. The structure consists of [TIMe 2 {S(0)CNEt 2 }] units in which the thallium atom is coordinated to the two methyl carbons and to the S and 0 atoms of the bidentate monothiocarbamato (Tl-S = 2.766(3), TI-0 = 2.684(7) Ä). These units are connected by additional TI-0 bonds (Tl-O" = 2.690(7) Ä) and weak Tl-S interactions (Tl-S 1 = 3.315(3) Ä), giving rise to a supramolecular polymeric ribbon along the b axis with practically symmetrical TI-O-TI bridges. The IR and 1 H and 13 C NMR spectra of the compound are also discussed. / •N \ V C =N \ / .C-N \ (i) (in) Scheme I 231 Brought to you by |

“…[5,6] Potential "single source" candidates include diorganothallium(III) compounds (e.g., R 2 TlORЈ), which comprise the most stable and extensively studied class of organothallium(III) species. [7] However, intermolecular Tl···O interactions in these compounds result in dimeric or polymeric species in the solid state {e.g., [Ph 2 Tl(trop)] 2 (1; trop = tropolonate), [Me 2 Tl(acac)] ϱ (2; acac = acetylacetonate)} [8][9][10] and likely decrease their volatility.…”

Structural Effects of Varied Steric Bulk in 2,(4),6‐Substituted Dimethylthallium(III) Phenoxides

The structural effects of varied steric bulk on 2,(4),6‐substituted dimethylthallium(III) phenoxides has been examined. The facile reaction of Me3Tl with a series of 2,(4),6‐substituted phenols in toluene or diethyl ether resulted in the formation of the species [Me2TlO(2,6‐R2C6H3)]2 [R = H (4), Me (5), iPr (6), Ph (7)] and [Me2TlO(2,4,6‐tBu3C6H2)] (8). All compounds have been characterized by elemental analysis as well as their melting point; FTIR, FT‐Raman, solution 1H and 13C{1H} NMR spectroscopy; and X‐ray crystallography. The structures of 4–7 are dimeric through short intermolecular Tl–O interactions, which yield a symmetric Tl2O2 unit and a distorted seesaw C2O2 bonding environment for thallium. An increase in the steric bulk in 4–6 has little effect on Tl–O bond lengths, whereas the CMe–Tl–CMe bond angle was found to significantly decrease. Further, the phenoxide ligands in 5 and 6 were found to be oriented perpendicular to the Tl2O2 unit to minimize steric interactions. Alternatively, compound 7 shows an increase in Tl–O bond lengths and an increase in the CMe–Tl–CMe bond angle compared to 4–6, and orientation of the phenoxide ligands perpendicular to the Tl2O2 core. The significant steric bulk imposed by the –O(2,4,6‐tBu3C6H2) ligand in 8 precludes dimer formation and allows for isolation of a monomeric species that contains a three‐coordinate T‐shaped C2O bonding environment for thallium. DFT calculations show that the energetic favorability of dimer formation decreases with increased phenoxide steric bulk.
