Crystallographic report: Chlorodiphenyltin(IV) piperidine-1-carbodithioate

The amazing structural diversity in organotin compounds is discussed in the systems containing -O and -S donor ligands. It is demonstrated that there exist a fascinating range of structural diversity for organotin(IV) complexes, including differences in coordination number and molecular geometry. The difference in structure is correlated with the nature of tin and ligand bonded R groups. Despite the large number of different structures found in organotin(IV) carboxylates, there is limited range of coordination geometries about the Sn atom. The four coordinated Sn atom in triorganotin(IV) complexes is invariably distorted tetrahedral and five coordinated Sn is distorted trigonal bipyramidal. A large range has been observed for diorganotin carboxylate structures, where five, six and seven coordinate geometries have been reported. The Sn atom in mono-organotin has only been demonstrated to exist in distorted octahedral geometries (the single exception being a pentagonal bipyramidal geometry). In the case of organotin(IV) complexes of S donor ligands, it has been shown that there exists a rich diversity in Sn atom geometries and coordination modes of the sulfur donor ligands themselves. As in related carboxylate systems, the assignment of coordination numbers to the Sn centers in some compounds is controversial. As a general trend, it has been shown that, the overall coordination number at the Sn atom decreases with the increasing number of organic substituents at the Sn atom. This phenomenon is usually achieved by increased asymmetry in the mode of coordination of the sulfur donor ligands.

“…Organotin compounds as well as dithiocarbamates ligands [22] are known for their antifungal [23], antibacterial [24], and antitumoral [25][26][27][28] activities. In the continuation of our interest in synthesis, structural elucidation, and antimicrobial activity of organotin(IV) complexes of thiocarboxylic acid [29][30][31], we report here the synthesis, structural elucidation, and antimicrobial activity of stannic(IV) complexes of piperidine-1-thiocarboxylic acid (Fig. 1).…”

A series of organotin(IV) thiocarboxylates have been synthesized with the general formula R2SnL2 and R3SnL (R = Ph2(I), Me3(II), n‐Bu3(III), Ph3(IV), Cy3(V), Me2(VI), n‐Bu2(VII), and L = piperidine‐1‐thiocarboxylic acid) in anhydrous toluene under the reflux conditions. The complexes were characterized by microanalysis, IR, 1H and 13C NMR, mass spectrometry, and XRD. NMR data revealed that thiocarboxylic acid acts as bidentate, and complexes exhibit the four‐coordinated geometry in solution state. In solid state, diorganotin complexes exhibit the hexa‐coordinated geometry whereas the triorganotin(IV) compounds show the five‐coordinated geometry. These complexes were also tested for their antimicrobial activity along with the ligand against different animals, plant pathogens, and Artemia salina. All complexes with few exceptions show high activity as compared to the ligand. © 2007 Wiley Periodicals, Inc.

“…We synthesized a series of compounds (1)(2)(3)(4)(5) to study their thermal and biological behavior. Two of the compounds, (2) and (5) have not been previously reported, whereas the synthesis and 1 H NMR of the three compounds are reported in the literature [3].…”

Chloro-diorganotin(IV) complexes of pipyridyl dithiocarbamate: Syntheses and determination of kinetic parameters, spectral characteristics and biocidal properties

et al. 2006

Organotin complexes of the general formula R 2 Sn(Cl)L have been synthesized where R = CH 3 , C 2 H 5 , C 4 H 9 , C 6 H 5 , C 7 H 7 , and L = 1-piperidinecarbodithioic acid. These complexes have been characterized by elemental analysis, FT-IR, 1 H NMR and mass spectrometry. The spectroscopic and XRD data shows that the dithiocarbamate ligand acts as a bidentate ligand. These complexes were also tested for biocidal activity. Thermal studies of the reported complexes have been carried out to investigate the degradation pattern and thermal stability while kinetic parameters were calculated from the thermogravometric (TG) trace. Silent features of X-ray structures for (1) and (4) are also given.
