Indium complexes bearing donor-functionalized alkoxide ligands as precursors for indium oxide thin films

Add time:08/20/2019    Source:sciencedirect.com

Novel indium complexes [(CH3)2In(OR)]2 (1–7) were synthesized using a series of donor-functionalized alkoxide ligands as potential precursors for thin-film applications. These complexes showed dimeric configurations with two μ2-O bridging between the metal centers. Moreover, the indium metal centers in these complexes exhibited pentacoordinated states with distorted trigonal-bipyramidal geometry. The complexes were characterized by Fourier transform (FT)-infrared, and FT-nuclear magnetic resonance spectroscopies, elemental analyses, and thermogravimetric analyses (TGA). The TGA curves of complexes 4 and 7 exhibited a single-step mass loss at 100–275 °C, indicating good volatility and thermal stability.
