“…The higher Λ M values for some complexes may be due to steric factors and donor behavior of DMSO to result in probable dissociation into solvated cation and 3-APY-{Sal}along with Clin DMSO. This conductance behavior of tellurium(IV) Schiff base complexes is different from those of transition metal complexes 67 which are reported to be non-electrolytes.…”

Monobasic (ON) bidentate Schiff base ligand has been prepared by condensing o-hydroxybenzaldehyde with 3-aminopyridine. The new organyltellurium(IV) complexes, having formula [TeCl 3 (3-APY-{Sal})], [RTeCl 2 (3-APY-{Sal})] and [R 2 TeCl(3-APY-{Sal})] have been synthesized by reacting equimolar ratio of Schiff base (3-APY-{SalH}) with TeCl 4 , RTeCl 3 and R 2 TeCl 2 : where R=4-methoxyphenyl, 4-hydroxyphenyl, 3-methyl-4-hydroxyphenyl. The characterization of Schiff base and its complexes were carried out by elemental analyses, conductivity measurements, FTIR and 1 H NMR spectral studies. Also, the biological activities (antifungal and antibacterial) of the Schiff base ligand and some of its tellurium(IV) complexes have been studied.

Eight new organyltellurium(IV) chelates with bidentate Schiff base formed by condensation of o-vanillin and 2-aminophenol having formula o-VAPH.RTeCl 2 , o-VAPH.R 2 TeCl have been synthesized and characterized by elemental analyses, molar conductance, infrared and proton nuclear magnetic resonance spectral studies. The data predict the pentacoordination of tellurium atom by monobasic bidentate(ON) Schiff base having Ψtrigonal bipyramidal geometry. Some of these complexes have also been observed to possess antifungal and antibacterial activity. ExperimentalAll preparations were carried out under dry N 2 atmosphere and the solvents used were purified by standard method 65,66 before use. The purity of compounds was checked by TLC using silica gel-G (Merck). Melting points were determined in open capillary tube and are uncorrected.Carbon, hydrogen and nitrogen analyses were obtained microanalytically on a Thermo-Finnigan CHNS analyser from SAIF, Panjab University Chandigarh. Conductivity was measured in DMSO at 25±2 o C with a microprocessor based conductivity bridge type MICROSIL.Infrared spectra were recorded in KBr pellets on a FT-Infrared spectrophotometer model RZX (Perkin Elmer) at SAIF, Panjab University Chandigarh. Proton magnetic resonance spectra were recorded in DMSO-d 6 using TMS as an internal reference on BRUKER AVANCE II 400 NMR spectrometer. The antimicrobial screening was carried out by tube dilution method

Mixed ligand metal complexes of Cr III , Fe III,II , Ni II and Cu II have been synthesized using 5-chlorosalicylic acid (5-CSA) as a primary ligand and L-Valine (L-Val) as secondary ligand. The metal complexes have been characterized by elemental analysis, electrical conductance, magnetic susceptibility measurements and spectral studies. The electrical conductance studies of the complexes indicate their electrolytic nature. Magnetic susceptibility measurements revealed paramagnetic nature of the all complexes. Bonding
