Chemistry of organoindium hydrides. Synthesis, characterization, and crystal structure of K{H[In(CH2CMe3)3]2}

Two new organoindium hydrides have been prepared and fully characterized according to their physical properties, partial elemental analyses, molecular weight studies and IR and 1H and 13C NMR spectral studies. The unique hydrogen atoms bonded to indium in the two compounds provide characteristic infrared bands and 1H NMR resonances which have been identified by comparative studies with the corresponding deuterium derivatives. Compounds which contain indium hydrogen bonds are difficult to prepare, isolate and fully characterize. Thus, no indium hydride has been fully characterized previously by elemental analyses, molecular weight studies, diagnostic spectroscopic data and an X-ray structural study.
