Indium hydride
Encyclopedia
Indium hydride is a binary compound of hydrogen and indium
. Despite claims the compound has never been synthesised but monomeric InH3 has been observed in matrix isolation
. Gas phase stability has been predicted The infrared spectrum was obtained in the gas phase by laser ablation
of indium in presence of hydrogen gas Several indium hydride complexes have been reported. . Examples of complexes with two hydride ligands replaced by other ligands are K3[K(Me2SiO)7][HIn(Me3CCH2)3]4 and HIn(2-Me2NCH2-C6H4)2. Indium hydride is also known to form adducts with carbene
s and with phosphines, for example in the compound H3InP(Cy)3 . The In-H bond length
is estimated at 170 pm compared to 148 pm for the Ga-H bond and 153 pm for the Al-H bond.
Indium
Indium is a chemical element with the symbol In and atomic number 49. This rare, very soft, malleable and easily fusible post-transition metal is chemically similar to gallium and thallium, and shows the intermediate properties between these two...

Matrix Isolation
Matrix isolation is an experimental technique used in chemistry and physics which generally involves a material being trapped within an unreactive matrix. A host matrix is a continuous solid phase in which guest particles are embedded. The guest is said to be isolated within the host matrix...

Laser ablation
Laser ablation is the process of removing material from a solid surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser flux, the material is typically converted to a plasma...

Carbene
In chemistry, a carbene is a molecule containing a neutral carbon atom with a valence of two and two unshared valence electrons. The general formula is RR'C:, but the carbon can instead be double-bonded to one group. The term "carbene" may also merely refer to the compound H2C:, also called...

Bond length
- Explanation :Bond length is related to bond order, when more electrons participate in bond formation the bond will get shorter. Bond length is also inversely related to bond strength and the bond dissociation energy, as a stronger bond will be shorter...
