| Abstract: | Polyol Metal Complexes. 17. Crystalline Iron(III) Complexes with Twofold Deprotonated Anhydroerythritol Ligands Three new crystalline ferrates(III) with diolato ligands derived from anhydroerythritol by deprotonation have been synthesized from wet alcoholic and from aqueous solution. Almost colourless, monoclinic crystals of Na2Fe(AnEryt-H-2)2(OH)] · 0.5 NaNO3 · 3.5 H2O ( 1 ) have been prepared from ethanolic solutions. They content mononuclear bis diolato hydroxo ferrate(III) dianions. Trinuclear hexakis diolato μ3-methoxo triferrat(III) tetraanions constitute the anionic part of Na4Fe3(AnErytH-2)6(OMe)] · 2.5 NaNO3 ( 2 ), yellow-green hexagonal crystals of which are formed from wet methanolic solutions. Yellow-green triclinic crystals of Ba2Fe2(AnEryt-H-2)4(μ-OH)2] · 12 H2O ( 3 ) have been precipitated from aqueous solutions. In 3 , the anions of 1 are dimerized to give tetrakis diolato di-μ-hydroxo diferrat(III) tetraanions. |
