Dichlorine-Containing Chlorothallate (III) (Me 4 N) 3 Tl 2 Cl 9 (Cl 2): Crystal Structure and Thermal Stability

Key Points

The complex demonstrates high thermal stability, remaining stable up to 140 °C.
X-ray single-crystal diffractometry revealed significant Cl···Cl noncovalent interactions in the structure.
Raman spectroscopy was utilized to examine features of halogen contacts within the complex.
These findings may advance the understanding of thallium chemistry and supramolecular interactions.

Abstract

The first example of a supramolecular complex of high-valent thallium (III) -containing "trapped" dichlorine, (Me4N) 3Tl2Cl9 (Cl2) (1), has been prepared. 1 was characterized by X-ray single-crystal diffractometry, indicating the presence of the "trapped" dichlorine unit with prominent Cl···Cl noncovalent interactions. The complex demonstrates a relatively high thermal stability (up to 140 °C). Features of the Cl···Cl halogen contacts were examined by Raman spectroscopy.
