ON THE DIOXIMINE COMPLEXES OF TRANSITION METALS. PART XCVII. a-SUBSTITUTED OXIME DERIVATIVES IN THE SPECTROPHOTOMETRIC DETERMINATION OF COBALTl

Abstract

The formation conditions, composition, stability and analytical application of some ternary complexes: Co(II):11:X=1:2:2(11=aJiphatic and alycyclic a-dioximes; X=N;-, 1-), binary derivatives: Co(II):12 =a-ketoximes: diacetylmonoxime, methyl-isopropyl dione monoxime, 1,2,3-cyclohexane trione dioxime (1,3)), Co(II): 1 3=1:2 (13 =condensation products of ketoximes with semicarbazide, thiosemicarbazide) and Co(II):14=Schiff's bases with ethylenediamine and hydrazine) were studied spectrophotometrically. The electronic spectra of these complexes were recorded and discussed.
