Formation and Structural Characterization of Metal Complexes derived from Thiosalicylic Acid

Abstract

The formation and structural aspects of some metal complexes of thiosalicylic acid (TSA) were studied. The μ‐bridging tetra‐coordinated Ru complex, [Ru(C6H4(CO2)(μ‐S)(H2O)]2 (1) was formed by hydrothermal reaction of TSA with RuCl3. The complexes [M(dtdb)(phen)(H2O)]n (2–4) (M = ZnII, CoII, NiII, dtdb = 2,2′‐dithiodibenzoate anion, phen = 1,10‐phenanthroline) were obtained by the slow diffusion technique and the in situ S–S bond formation was confirmed by elemental, spectral and X‐ray analysis. Reaction of TSA with CuCl2 and 2,2′‐bipyridine (bipy) under the slow diffusion technique yielded the dimer [Cu(tdb)(bipy)] (5) (tdb = thiodibenzoic acid), where the in situ generation of 2,2′‐thiodibenzoic acid was observed.

“…[ 20 ] Besides, FT‐IR peaks associated with the stretching vibration of terminal V = O bonds were also detected at 1007 and 1019 cm −1 (Figure S21a, Supporting Information). [ 17,21 ]…”

“…Again, a new peak at 475 cm –1 has appeared, suggesting the formation of the S–S bond (Figure S3). Therefore, the generation of the S–S bond in 1 has been corroborated by IR spectroscopy. The thermal stability of 1 was examined by thermogravimetric analysis (TGA) within the temperature range of 32–900 °C (Figure S4).…”

“…In this regard, we thought of utilizing 4-mercaptobenzoic acid (4-mba) for the purpose of in situ generation of 4,4′-disulfanediyldibenzoic (H 2 4,4′-dsb) in the synthesis of CPs (Scheme ). The in situ ligand generation also puts forward the concept of omitting the necessity of ligand preparation prior to the complex formation reaction . Due to its unique ability to develop compounds that cannot be produced via conventional synthetic pathways, in situ ligand synthesis has recently become a favored synthetic pathway to harvest new CPs .…”

“…Moreover, in contrast with discrete MOP-1, the cuboctahedral clusters of IMU-108 are cage-based, rmly linked by in-situ S-S bonds. The S-S additional bond provides further rigid structure and stability [71][72][73][74] . To con rm our envision, a stability test of IMU-108 was performed.…”
