[2,6‐iPr₂C₆H₃(Me₃Si)NTl]₄—A Covalent Thallium(I)‐Nitrogen Compound with Weak Arene–Thallium Interactions

Abstract

Weak arene–thallium interactions and T1T1 contacts stabilize the molecular framework of the tetrameric title compound in the solid state. The picture on the right shows two monomeric units and the central T14 ring. The first covalent TlI compound can be prepared easily from LiN(SiMe3)(2,6‐iPr2C6H3) and T1C1 in n‐hexane.

Synthesis, characterisation and theoretical studies of amidinato-indium(i) and thallium(i) complexes: isomers of neutral group 13 metal(i) carbene analogues

Highly polyhapto–aromatic interactions in thallium(I) coordination

“…Hence, the Tl(I) coordination sphere is completed and rather than a TlO 4 coordination sphere, the complex can be considered to contain a 2 · g 6 (C 12 O 4 Tl) center with a 16 coordination number, this coordination number and this structural behavior were exactly observed in thallium(I) salicylate [9,16]. The reported Tl Á Á Á C separations range is 3.20-4.00 Å in recent reported species [2,20] and the sum of the vander Walls radii of carbon and Tl atoms is 3.66 Å [21]. Thus, 2 · g 6 aromatic coordination of Tl(I) appears to be yet another factor which can make varying contributions to the stability of complexes of this metal ion.…”

Synthesis and characterization of four new thallium(i) tetrazole supramolecular compounds with various secondary interactions; new precursors for thallium(iii) oxide nano-particles

“…The Tl I coordination polymers are interesting and frequently studied in considering the "stereochemical activity" of valence shell electron lone pairs, potential ability to form metal-metal bonds and also complexes with aromatic hydrocarbons. [1][2][3][4][5][6][7][8][9][10] Thallium is a heavy element of group 13, which has two oxidation states of +1 and +3. 11,12 Besides, the synthesis of nano metal oxides with different morphologies has been of significant interest in material science and industry in the last decade.…”
