Characterization of some triphenyltin(IV) complexes of 5-(arylazo)salicylaldehyde ligands using IR, 1H, 13C, 119Sn NMR and 119Sn Mössbauer spectroscopy

Synthesis and characterization of tributyltin(IV) complexes of 2-[(E)-2-(3-formyl-4-hydroxyphenyl)-1-diazenyl]benzoic acid and 4-[((E)-1-{2-hydroxy-5-[(E)-2-(2-carboxyphenyl)-1-diazenyl]phenyl}methylidene)amino]aryls – crystal structures of polymeric (Bu3Sn[O2CC6H4{NN(C6H3-4-OH-5-CHO)}-o])n and (Bu3Sn[O2CC6H4{NN(C6H3-4-OH(C(H)NC6H4Cl-4))}-o])n – toxicity studies on the second instar of Aedes aegypti mosquito larvae

“…doi:10.1016/j.jorganchem.2004.08.038 desired features, e.g., having an intense light absorption in the visible region for colorimetric applications, have also been reported. These organic reagents are commonly known as 5-(arylazo)salicylaldehyde (AAS) and were used by several workers in order to characterize U(VI) [4], Pd(II) [4], Co(II) [5], Cu(II) [6,7], Ni(II) [8], Mn(II) [9], Sn(II) [10] and Sn(IV) [11] complexes in both solid and solution states. A few transition metal complexes also show semi conducting properties in the temperature range 310-340 K [9].…”

Organotin Compounds: Perspectives and Potential

“…Their Sn(II) and Sn (IV) complexes have also received attention in the recent past. 63 ' 64 The reactions of Sn (IV) and organotin (IV) pseudohalides with 2-hydroxy-l-naphthalideneimine 65 The spectroscopic characterization of adducts of SnCl 2 with imidazole and its derivatives like 1-methyl-4-methyl-, and 1, 2-dimethyl-, has been reported even up to the late eighties 75 . In 1990 Vasnin et al 76 .…”

Triphenyltin(iv) Complexes of Some Monobasic Bidentate Schiff Bases

“…32 Table 2: 'H and " 9 Sn NMR spectral chemical shifts (δ in ppm) of triphenyltin(IV) chelates, Ph 3 The ö(" 9 Sn). 37 This low value may be due to the partial dissociation of the complex 7a in solution. 5 The ö(" 9 Sn) values also depend upon the nature of groupings attached to tin and the ligand bite.…”
