Journal ArticleDOI
Inner coordination sphere tin(IV) complexes with some O,N,N-terdentate {N-(2-hydroxybenzaldehyde)-1-amino-2-phenyleneimine and N-(2-hydroxy-1-naphthaldehyde)-1-amino-2-phenyleneimine} and O,N,N,O-quadridentate {N,N′-bis(2-hydroxybenzaldehyde)-1,2-phenylenediimine and N,N′-bis(2-hydroxy-1-naphthaldehyde)-1,2-phenylenediimine} Schiff bases
TL;DR: From the reactions of SnCl4 with organotin(IV) chlorides (RSnCl3, R2SnCl2 and R3SnCl), a series of complexes have been synthesized and characterized, respectively, by microanalytical, IR, and 1H NMR spectroscopic methods as mentioned in this paper.
Journal ArticleDOI
Synthesis, crystal structure and biological activity of thiophene-2-carboxaldehyde thiosemicarbazone and its tin complexes
TL;DR: In this paper, the crystal structure determination showed that in both 1 and 2, tctscH is deprotonated and functions as an anionic bidentate ligand, coordinating to the tin atom through its azomethine-N and thiol-S atoms.
Journal ArticleDOI
Synthesis and characterization of di-n-butylbis(2,4-dihydroxybenzoato)tin(IV)
TL;DR: The compound di-n-butylbis(2,4-dihydroxybenzoato)tin(IV), (C4H9)(2)Sn[2, 4-(OH)2)C6H3COO](2) has been synthesized and characterized by elemental analysis, IR and NMR (H-1, C-13 and Sn-119) spectroscopy and X-ray diffraction techniques as discussed by the authors.
Journal ArticleDOI
Synthesis and crystal structure of di-n-butylbis(2-amino-5-chlorobenzoato)tin(IV)
TL;DR: In this paper, the six-coordinate diorganotin dicarboxylate monomer was shown to have a skew-trapezoidal bipyramid geometry.
Journal ArticleDOI
Synthesis, crystal structure and biological activity of bis(acetone thiosemicarbazone-S)dichlorodiphenyltin(IV)
TL;DR: The reaction between diphenyltin(IV) dichloride and======thiosemicarbazide using acetone-ethanol as solvent resulted in theformation of bis(acetone======σ)dichlorodiphenyltins(IV),======SnPh======€€€£££ £££€£ £ £ ££€ ££ £€£€€ £ £€ £€€ €££
