⭐. Gallium forms a dimeric hydride Ga2H6(digallane) and indium forms a polymeric hydride(InH3)n.

⭐. The hydride of gallium and indium are not very stable.

⭐. Thallium does not form any hydride

⭐. Boran aluminium and galliun form complex anionic hydrides such as

✨. NaBH4 --- sodium borohydride.

✨. LiA/H4----Lithium aluminium hydride.

✨. LiGaH4-----Lithium gallium hydride.
