Synthesis and Application of Monomeric Chalcogenolates of 13 Group Elements

Abstract

Utilization of the N,C,N‐chelating ligand L (L={2,6‐(Me2NCH2)2C6H3}−) in the chemistry of 13 group elements provided either N→In coordinated monomeric chalcogenides LIn(μ‐E4) (E=S, Se) with unprecedented InE4 inorganic ring or monomeric chalcogenolates LM(EPh)2 (M=Ga, In). Complex LGa(SePh)2 was selected as the most suitable single source precursor (SSP) for the deposition of amorphous semiconducting GaSe thin films using spin coating method.

Characterization of an unanticipated indium-sulfur metallocycle complex

“…2.4-2.5 Å) and In(I)-S bonds (typically approx. 2.7 Å) [29][30][31]. The In-In distance is 3.214 Å, eliminating the possibility of In-In bonds, typically reported to be 2.7-2.8 Å [16].…”

“…If this is a slow or low-yielding process, that may explain the observed low yield and phase-impure solid product. The decomposition of DMSO into methanethiol (figure 3a) via an acid-catalysed Pummerer rearrangement has been well studied [30,[41][42][43]. In the presence of strong acids such as HNO 3 , DMSO forms formaldehyde hemithioacetal, which decomposes to methanethiol and formaldehyde.…”
