Polynuclear coordination precursor compounds for M3Fe5O12 garnets (M = Y, Eu, Gd and Er). Part I. Synthesis of the precursors

Abstract

4 = tartarate anion, C6O7H – 11 = gluconate anion � have been synthesized and characterised by elemental chemical analysis and physico-chemical measurements (IR, UV-Vis spectroscopy and magnetic determinations). The synthetic possibilities offered by the use of these new compounds as potential precursors for garnets have been suggested
