Template:Chembox Footer/trackingTemplate:Short description

Indium trihydride is an inorganic compound with the chemical formula (Page Module:Chem2/styles.css has no content.InH3). It has been observed in matrix isolation and laser ablation experiments.[2][3] Gas phase stability has been predicted.[4] The infrared spectrum was obtained in the gas phase by laser ablation of indium in presence of hydrogen gas.[5] Page Module:Chem2/styles.css has no content.InH3 is of no practical importance.

Chemical properties

Solid Page Module:Chem2/styles.css has no content.InH3 is 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 Page Module:Chem2/styles.css has no content.InH3 and Page Module:Chem2/styles.css has no content.InD3 produced on a solid hydrogen matrix are warmed.[5] Such a structure is known for solid Page Module:Chem2/styles.css has no content.AlH3.[6] When heated above −90 °C, 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 indane below −90 °C.Template:Cln

Several compounds with In-H bonds have been reported.[7] Examples of complexes with two hydride ligands replaced by other ligands are Page Module:Chem2/styles.css has no content.(K+)3[K((CH3)2SiO)7]+([InH(CH2C(CH3)3)3]−)4[8] and Page Module:Chem2/styles.css has no content.HIn(−C6H4−ortho-CH2N(CH3)2)2.

Although Page Module:Chem2/styles.css has no content.InH3 is labile, adducts are known with the stoichiometry Page Module:Chem2/styles.css has no content.InH3Ln (n = 1 or 2).[9] 1:1 amine adducts are made by the reaction of Page Module:Chem2/styles.css has no content.Li+[InH4]− (lithium tetrahydridoindate(III)) with a trialkylammonium salt. The trimethylamine complex is only stable below −30 °C or in dilute solution. The 1:1 and 1:2 complexes with tricyclohexylphosphine (Page Module:Chem2/styles.css has no content.PCy3) have been characterised crystallographically. The average In-H bond length is 168 pm.[7] Indium hydride is also known to form adducts with NHCs.[10]
