摘要：The present paper is a report on the synthesis of some new tin (II) and tin (IV) complexes by the reaction of stannous chloride and dimethyltin dichloride with semicarbazones and thiosemicarbazones using tetrahydrofuran(THF) as reaction medium. Semicarbazones and thiosemicarbazones used in these studies are synthesized by the condensation of 1-acetyl-2-naphthol, 2-acetyl-1-naphathol, 2-acetyl-5-methyl furan, 2-acetyl-4-methyl thiophene and 2-acetyl-naphthalene with semicarbazide/ thiosemicarbazide. The bonding pattern and geometry of tin complexes are characterized by spectroscopic evidences. The ligands and their metal complexes have been screened for antitubercular, antibacterial and antifungal activities and are found quite active in this respect. Plant growth activity has also been evaluated and is found negative growth.
