Reactions of Indium (III) Isopropoxide with Thio-Schiff Bases Derived from S-Methyl-dithiocarbazate

Abstract

Reactions of indium (III) isopropoxide with monobasic thio-Schiff bases, such as S-methyl-β-N-(furfurylmethylene)-dithiocarbazate (TSB₁H), S-methyl-β-N-(phenylmethylene)dithio-carbazate (TSB₂H), S-methyl-β-N-(phenylethylene)dithiocarbazate (TSB₃H), S-methyl-β-N-(diphenylmethylene)dithiocarbazate (TSB₄H), S-methyl-β-N-(cyclopentyl)dithiocarbazate (TSB₅H), S-methyl-β-N-(cyclohexyl)dithiocarbazate (TSB₆H), and dibasic thio-Schiff bases, such as S-methyl-β-N-(2-hydroxyphenylmethylene)dithiocarbazate (TSB₁′H₂) and S-methyl-β-N-(2-hydroxyphenylethylene)dithiocarbazate (TSB₂′H₂), have been studied in dry benzene in 1:1, 1:2 or 2:3 molar ratios under anhydrous conditions. The compounds of the type In(OPrⁱ)_3-nL_n, (OPrⁱ)InL′ and In₂L₃′, where L = monobasic thio-Schiff base, L′ = dibasic thio-Schiff base and n = 1, 2, have been synthesized and characterised by elemental analysis, molecular weight and spectral (infrared, ¹H NMR and electronic) studies.
