is the simplest thallane. Thallium is the heaviest stable member of the group 13 metals; the stability of group 13 hydrides decreases with increasing periodic number. This is commonly attributed to poor overlap of the metal valence orbitals with that of the 1s orbital of hydrogen. Despite encouraging early reports, it is unlikely that a thallane species has been isolated. Thallanes have been observed only in matrix isolation studies; the infrared spectrum was obtained in the gas phase by laser ablation of thallium in the presence of hydrogen gas. This study confirmed aspects of ab initio calculations conducted by Schwerdtfeger which indicated the similar stability of thallium and indiganes. There has not been a confirmed isolation of a thallium hydride complex to date.
