Synthesis, characterization and reactivity of (dithiolato)indium complexes

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

“…The molecular structure of [2] showed a trigonal-bipyramidal coordination sphere for the indium ion, where the trigonal basal plane is formed by two sulfur atoms of the dianionic thiolate ligand, and the oxygen atom of the N,O-ß-heteroarylalkenolate ligand while the apical positions are occupied by the nitrogen atom present in the bridging amine group of the dianionic thiolate ligand and one nitrogen atoms of the heteroarylalkenolate ligand. The In-S bond distances (TableS1) in [1] were found to be in the range of 2.404(1)-2.676(2) Å, while the bond lengths of the bridging sulfur atoms in In1-S2 and In1_a-S2 were found to be longer at 2.485(1) Å and 2.676(2) Å respectively than the terminal In1-S1 bond length at 2.404(1) Å.These values correspond well with similar reported values of dimeric, trimeric and oligomeric organoindium compounds [33][34][35][36][37]. The In-N bond length (2.393(5) Å) and In-Cl bond length (2.415(1) Å) in [1] are both within the reported ranges 35,[38][39][40][41].…”

“…These values correspond well to similar reported values of dimeric, trimeric and oligomeric organoindium compounds. [33][34][35][36][37] The In-N bond length (2.393(5) Å) and In-Cl bond length (2.415(1) Å) in [1] are both within the reported ranges. 35,[38][39][40][41] Notably, the three dependent indium sub-units in [1] and their corresponding atoms display uniform bond lengths and angles.…”

“…The In1–O1 bond length of 2.089(2) Å is notably shorter compared to those observed in complexes with higher coordination numbers, such as [(SOOS)In(py)(NO 3 )], [(SNNS)In(OAc)], [(NNS 2 )In(NO 3 )], [(NNS 2 )In(OAc)], and [(SNNSPr)In(OAc)] complexes with In–O bond lengths in the range of 2.162(4)–2.851(4) Å. 33 The equatorial positions of both compounds [1] (S2–In–S1) and [2] (S2–In1–S1) exhibited deviations from the ideal equatorial geometry of 120°, which are manifest in the distorted bond angles of 131.40(4) and [(127.98(3)°) (cal. 125.13°)], respectively.…”
