ON THE DIOXIMINE COMPLEXES OF TRANSITION METALS. LXXXVII. SPECTROPHOTOMETRIC STUDIES ON THE FORMATION OF SOME RHENIUM COMPLEXES WITH α-SUBSTITUTED ALICYCLIC OXIME DERIVATIVES

Abstract

The formation conditions, stability in acidic aqueous solutions (Re(IV) : oxime = 1 : 4) and the analytical application of some rhenium complexes with 1,2-cyclohexane dione dioxime and 1,2-cyclododecanedione dioxime and 1,2,3- cyclohexane trione dioxime (1,3) deriva- tives: -2-hydrazone, -2-semicarbazone, 2-thiosemicarbazone and -2-phenylhydrazone were studied. The spectrophotometric measurements were carried out in hydrochloric acid medium in the presence of tin(II) chloride as reducing agent.
