Study on 4-Methoxybenzohydroxamate Complexes of Aryltellurium (IV) and Diaryltellurium (IV)

Sonu Chauhan, Deepak, Sapana Garg and K. K. Verma

Twelve new complexes of the 4- methoxybenzohydroxamate with aryltellurium (IV) and diaryltellurium (IV) of type RTeCl2.L, RTeCl.L2, R2TeCl.L and R2Te.L2 (where R = 4-methoxyphenyl, 4-hydroxyphenyl, 3-methyl-4-hydroxyphenyl and L = 4-methoxybenzohydroxamate) have been synthesized by reactions of RTeCl3 and R2TeCl2 with potassium 4-methoxybenzohydroxamate. They have been characterized by elemental analyses, molar conductance, FT-IR and 1H NMR spectroscopy. The spectral studies predict the bonding of ligand through hydroxylamine and carbonyl oxygens (O, O′) coordination to give penta- and hexa- coordinated tellurium (IV) complexes. The complexes also have been screened for their antimicrobial activity against various bacteria and fungi organisms and it has been observed that they are more active against fungi as compared to Gram +ve and Gram –ve bacteria.
