Spin-Orbit Configuration Interaction Energies Applied to the Ground and Excited Electronic States of Thallium Hydride. 

Such is the weakness of In-H and Tl-H bonds that the chemistry of indium and thallium hydrides is unlikely to rival that of the corresponding aluminum and gallium compounds. This is certainly the inference to be drawn from the thermal instability of the known compounds LiInH4 and LiTlH4, both of which decompose rapidly at 273 K (similar... 

The hydrides of thallium, like those of lead and bismuth, are unstable. However, the componnd LiTlH4 has claimed to be a relatively stable thallium hydride. Solid LiTlH4 is easily prepared from TICI3 using lithium hydride (equation 1) ... 

Table 6 Vibrational assignments for indium and thallium hydrides (jcmT1)...

Spinor Mulliken populations and Tl-H bond lengths for some thallium hydrides are summarized in Table 10. TI2H2 has a D2 , di-H-bridged structure as previously reported (Figure 1) [81,82], and no additional minimum structure... 

Test calculations on excited states of thallium hydride correlating 14 electrons, showed that this technique can accurately describe potential energy curves, but the Cl with single and double substitutions is only treated at the DGCI level and may become heavy if one wants to enlarge the reference space for a better correlation treatment.
