Abstract :
The Tl-F and Tl-Tl bonding in α-TlF and ß-TlF have been studied from 203, 205Tl and 19F NMR powder data. The off-ionic part of the Tl-Tl and Tl-F interactions is characterized by indirect spin-spin coupling 203Tl-205Tl, 205Tl-19F and thallium and fluorine nuclear magnetic shielding tensors. It is shown that structure distortions of α-TlF and ß-TlF are connected with a thallium 6s2 inert pair activation and with a Tl-Tl interaction of previously unnoted type.
