Thermal gallium compounds

It will be evident from the preceding account that not all physical methods lend themselves equally well to the detection and specification of the gallium hydrides. There are, for example, obvious difficulties in trying to grow single crystals of a low-melting, thermally unstable compound, and, although the case of hypofluorous acid (62) shows what can be achieved ultimately, X-ray methods do not obviously commend... 

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...
