Synthesis of New Tin(iv) Compounds of Substituted Diphenylsulfide Derivatives and Their Complexes With Some Neutral Ligands

Abstract

Some new tin(IV) compounds of the general formula Sn(SC 6 H 4 R) 4 , where R ¼ o-NH 2 , p-Me, p-Bu-t have been obtained from the direct reaction of (RC 6 H 5 S) 2 and tin metal in the molar ratio 2:1 in refluxing toluene. Similarly, a mixture of tin (RC 6 H 5 S) 2 and iodine in 1.0:1.5:0.5 or 1.0:1.0:1.0 molar ratios in refluxing toluene leads to the formation of Sn(SC 6 H 4 R) 3 I or Sn(SC 6 H 4 R) 2 I 2 , respectively. Complexes of the new tin compounds with triphenylphosphine, 4-picoline, 1,10-phenanthroline and 2,2 0 -bipyridine have been synthesized by the direct reaction between the tin compound and the *Current address:

Dissolution of Sn, SnO, and SnS in a Thiol–Amine Solvent Mixture: Insights into the Identity of the Molecular Solutes for Solution-Processed SnS

“…The Raman spectra obtained after dissolution of Sn, SnS, and SnO in EDT–en are nearly identical to one another in peak position, with each possessing major bands at ∼197, 264, and 322 (±3) cm –1 . It should be further noted that there are no significant bands in these spectra associated with the v (Sn–N) symmetric stretch at ∼178 cm –1 , which is readily observed with coordination of amines to 1 (see Supporting Information, Figure S6). , On this basis, it is unlikely that en in the solvent mixture is coordinating to tin, leaving the molecular solute solely ligated by two dithiolate ligands (vide supra).…”

Reactions of Pd2+and Pt2+with pyrrolidinedithio carbamate and cystine ligands: synthesis and DFT calculations

“…The appearance of new bands in the infrared spectra of the synthesized complexes 3-6 in the region 353-370 cm −1 , which is assigned to ν(M−S), supports the bonding of sulfur atom to the metal ion (25). In particular, the ν(C−N), ν(C−S) and ν(C=S) bands are known to depend on the nature of coordination of dithiocarbamate to metal ions (26). The dithiocarbamate ligand in [M(S 2 NC 5 H 8 ) 2 ] complexes act as bidentate ligand through the sulfur atoms.…”

“…PTD was prepared by refluxing of pyrrolidine and carbon disulfide in the presence of excess NaOH, followed by the addition of I 2 in methanol to the mixture (26). The molar ratio of pyrrolidine to carbon disulfide is 1:1, and the molar ratio of I 2 to the carbon disulfide is 1.2:1.…”

Synthesis of new Bismuth (III) compound and adducts of benzothiazol disulfide derivatives and their complexes with Co(II), Ni(II) and Cu(II)

“…The synthesis of dihalobis (2-pyridinethiolato) tin(IV) by an oxidative addition reaction of di-2-pyridyldisulfide to tin (II) halides represents an example of preparing other similar dihalodithiolato tin(IV) compounds (9) . In our previous studies (10,11) (12) .…”
