Synthesis and spectroscopic characterization of organotin(IV) complexes with 2-benzoylpyridine-N(4)-cyclohexylthiosemicarbazone (HBPCT): X-ray crystal structure of [PhSnCl2(BPCT)]

Organotin(IV) complexes of 2-hydroxyacetophenone-N(4)-cyclohexylthiosemicarbazone (H2dact): Synthesis, spectral characterization, crystal structure and biological studies

“…Although the organotin(IV) complexes exhibit important cytotoxic effects, but based on the literature review there is still very limited information available regarding the X-ray and biological studies of novel organotin(IV) complexes with substituted thiosemicarbazone ligands [23]. Previous works described the synthesis and structural studies of tin(IV)/organotin(IV) complexes with N(4)-substituted thiosemicarbazone ligand [24,25]. The particular interest of this work is a better understanding of the structural diversity of organotin(IV) complexes to delineate their biological properties.…”

Diorganotin(IV) complexes of 3,5-dichloro-2-hydroxybenzaldehyde-N(4)-ethylthiosemicarbazone: Synthesis, spectral characterization and crystal structure

“…The medium m(C aro -O) band at 1549 cm À1 for free ligand (1) is shifted to lower frequencies in the spectra of the complexes suggesting coordination via phenolic oxygen atom to tin(IV) ion. The frequency of m(N-N) band was found to shift to higher frequencies in the complexes compared to the free ligand further confirming the coordination via the azomethine nitrogen [41]. The free ligand (1) displayed two bands at 1367 and 857 cm À1 due to stretching and bending vibration of m(C@S), which is shifted to lower frequencies at 1331-1315 and 822-814 cm À1 range in the complexes (2-4), indicating the coordination via thiolate sulfur atom [42].…”

Synthesis, Characterization, and Antibacterial Activities of Organotin(IV) Complexes with 2‐Acetylpyridine‐N(4)‐cyclohexylthiosemicarbazone (HAPCT)

“…N (4)‐Cyclohexylthiosemicarbazide has been reported earlier in the literature . N (4)‐Cyclohexylthiosemicarbazide was synthesized as follows: Cyclohexylisothiocyanate (1.41 g, 10 mmol) in 4 mL of ether was added dropwise into 4 mL of ether solution of hydrazine hydrate (2 g, 40 mmol).…”

“…Among main‐group organometallic compounds, organotin has been receiving considerable attention in recent years , for some of them are biologically active or have been used as reagents or catalysts in organic reactions . Our group recently reported the structural and biological properties of organotin(IV) complexes with substituted thiosemicarbazones . The results reveal that N (4)‐cyclohexylthiosemicarbazones derived from 2‐benzoylpyridine and pyruvic acid and their organotin(IV) complexes show significant antibacterial activities.…”
