In 2022,Yang, Hui; Xing, Baoyan; Zhao, Jianguo; Ma, Guibin published an article in Polyhedron. The title of the article was 《Methoxyl-substituted phosphine ligand properties and a case study of formation adducts to indium(III) bromide by DFT calculations》.Formula: Br3In The author mentioned the following in the article:
Six bulky triphenylphosphine ligands containing substituted methoxyl groups (tris(2,4,6-trimethoxyphenyl)phosphine (TMP), tris(2,6-dimethoxyphenyl)phosphine (TDP), tris(o-methoxyphenyl)phosphine (o-Anis3P), tris(p-methoxyphenyl)phosphine (p-Anis3P), tris(m-methoxyphenyl)phosphine (m-Anis3P) and triphenylphosphine (PPh3)) were studied by DFT (d. functional theory) calculations and exptl. solution/solid-state 31P NMR spectroscopy. The basicity and binding ability of these substituted ligands, proven by comparison of structural data with DFT-predicted data, are in the order TMP > TDP > o-Anis3P > p-Anis3P > m-Anis3P > PPh3. Mol. structures for InBr3 with bulky ligands (TMP, TDP, o-Anis3P, p-Anis3P, m-Anis3P and PPh3) were calculated using DFT. P-In bond distances generated from these six optimized mol. structures and the calculated intramol. interaction energies are in agreement with the ligand properties, with strong donation ability for those with the short bond distance; the In-P bond distance from shortest to longest follows a similar trend as predicted by DFT calculations DFT calculations for these adducts show that methoxyl substitution to triphenylphosphine (PPh3) ligands contributed to its electron donor ability resulting in lower P-In bond distances with relatively large bond interaction energies. In the part of experimental materials, we found many familiar compounds, such as Indium(III) bromide(cas: 13465-09-3Formula: Br3In)
Indium(III) bromide(cas: 13465-09-3) is used as a catalyst to produce dithioacetals when unactivated alkynes react with thiols and fields such as optics and microelectronics that utilize semiconductor technology have wide uses for indium in high-performing solar cells.Formula: Br3In
