Indium trihydride is an inorganic compound with the chemical formula (InH
3)n (also written as ([InH
3])n or InH
3). It is a covalent network solid, and as such, it is insoluble in all solvents. Moreover, it is unstable at standard temperature and pressure. It is a group 13 hydride.
The systematic name indium trihydride, a valid IUPAC name, is constructed according to the compositional nomenclature. Indium trihydride is also used to refer to the related molecular compound indigane and its oligomers. Care should be taken to avoid confusing the two compounds.
For solid InH3 a three-dimensional network polymeric structure, where In atoms are connected by In-H-In bridging bonds, is suggested to account for the growth of broad infrared bands when samples of InH3 and InD3 produced on a solid hydrogen matrix are warmed. Such a structure is known for solid AlH3. When heated above −90 °C (−130 °F), indium trihydride decomposes to produce indium–hydrogen alloy and elemental hydrogen. As of 2013, the only known method of synthesising indium trihydride, is the autopolymerisation of indigane below −90 °C (−130 °F).
