“…These compounds are relatively air stable, producing the same melting points and NMRs even after being left in air for a few days. Other Sn Ã/ Salen chelates have also been shown to be air stable [5,17,18]. ligand, and trans arrangement of the alkyl groups on tin, suggest an octahedral environment around the central tin atom (as shown in Scheme 1a).…”

“…[4] Semicarbazones and thiosemicarbazones are versatile ligands in both neutral and anionic forms. [5] Chelates of organotin(IV) moieties with N, O and S donor ligands [6,7] have received much attention during the last few years. Organotins have been used in industrial and agricultural applications as plastic stabilizers and catalysts, antifouling paints, molluscicides, fungicides [8] and disinfectants.…”

New series of triorganotin(IV) complexes with 4 -nitrobenzanilide semicarbazone (L 1 H) and 4 -nitrobenzanilide thiosemicarbazone (L 2 H) of the type [R 3 Sn(L)] (R = -CH 3 , -C 6 H 5 and n-C 4 H 9 ) were synthesized under microwave irradiation. All the complexes were characterized by elemental analysis, conductance measurements, molecular weight determinations and spectral data, viz., IR, UV-vis, 1 H, 13 C and 119 Sn NMR. The central tin atoms of these complexes are all five-coordinated with trigonal bipyramidal geometry. In order to assess their growth inhibitory potency semicarbazone, thiosemicarbazone and their triorganotin(IV) complexes were tested in vitro against some pathogenic fungi and bacteria. Also the ligands and their organotin(IV) complexes were studied to assess the effects of long-term ingestion of these compounds on fertility, body and reproductive organ weights. The biochemical analyses were also performed on blood samples and reproductive organs of male rats. The findings have been presented in this paper.

“…The asymmetrical stretching vibrations of C=N and C=C bonds are appeared as a strong band in the IR spectra, at 1751 cm -1 (for the ligand) and 1675 cm -1 (for the complex). On complexation, the υ (C=N) bands are shifted slightly to lower frequencies in the IR spectrum of Cu complex Dey et al, 1999;Pui et al, 2007;Ünver et al, 2006). For the 2-Clpym ligand and Cu complex, the stretching C-Cl vibration is appeared at 1135 and 1263 cm -1 , respectively.…”

“…The IR spectra of 2-Clpym ligand and its Cu(II) complex are presented in Figure 2. These spectra were investigated by comparing the calculated vibrational modes with those reported in the literatures (Dey et al, 1999;Pui et al, 2007;Ünver et al, 2006) Table 2.…”
