Indium crystal structure

The gallium and indium complexes of novel bis(thiosemicarbazones) have been investigated.71-73 Initial publications indicated a more complex stoichiometry where X-ray crystal structures suggested either dinuclear or trinuclear complexes. Whereas these complexes are quite interesting, they are less likely to result in useful nuclear medicine radiopharmaceuticals. The bis(thiosemi-carbazones) are quite useful as ligands for copper, and are discussed in more detail vide infra). 

In 1980 only a handful of indium amides had been characterized and only one X-ray crystal structure had been published. During the ensuing period the investigation of indium amides has been spurred by their possible applications in technology. In addition, there has been an interest in low coordinate and oxidation state compounds. Both indium amides"...
