Indium(iii)/2-benzoylpyridine chemistry: interesting indium(iii) bromide-assisted transformations of the ligand

Abstract

Reactions of 2-benzoylpyridine, (py)(ph)CO, with InX3 (X = Cl, Br) in EtOH at room temperature have been studied. The InCl3/(py)(ph)CO system has provided access to complex [InCl3{(py)(ph)CO}(EtOH)]∙{(py)(ph)CO} (1) and the...

Synthesis and theoretical study of a mixed-ligand indium(iii) complex for fabrication of β-In2S3 thin films via chemical vapor deposition

“…These values aligned with reported values. 23,[43][44][45][46][47] However, the slight bond elongation observed at 2.340(3) Å for In1-N1 reflects the weakening of the bond due to the greater donor strength of the thiolate ligand, as reported in similar complexes of aminothiolate ligand. 48 The observed and calculated bond length of In1-O1 were determined to be 2.…”

Interesting chemical and physical features of the products of the reactions between trivalent lanthanoids and a tetradentate Schiff base derived from cyclohexane-1,2-diamine

“…† The IR spectra of 1-11 are almost identical. The weak-tomedium intensity band at ∼3450 cm −1 with two submaxima at lower wavenumbers is due to the ν(OH) vibration of coordinated MeOH 39 and the ν(NH + ) vibration 15a of the coordinated L′H 2 ligand; the relatively low wavenumber and broadness of the band are both indicative of H bonding, which has been crystallographically confirmed (vide supra).…”
