Indium, triethyl

The procedures and apparatus for the preparation of high-purity triethyl-indium are essentially the same as those employed for the preparation of trimethylindium (as described in Section 7.A, parts a-d), and only the additional pertinent details relating to the preparation of triethylindium are given here. 

The rather complicated indium-phosphorus cluster framework 24 was obtained by the reaction of indium(III) chloride with PhP(SiMe3)2 in the presence of triethyl-phosphane [Eq. (12)] [29]. Apparently, a complex redox process occurred, in the course of which phosphorus atoms were oxidized by the formation of three P-P bonds, while six indium atoms were reduced from +3 to +2 accompanied by the formation of three In-In bonds. The In-In (average 274 pm) and P-P bond lengths (average 222 pm) represent localized single bonds. Other strategies for the... 

AlInP. Reacting PH3 with the trimethyl or trIethyl derivatives of aluminium and indium leads to the formation of ternary phosphide films of the two metals [50, 214 to 218], see also [219, 220].
