Preparative and Structural Studies of Halodimolybdates (II). II Preparation of (NH4)4Mo2Br8, (NH4)5Mo2Br9 · H2O,Rb5Mo2Cl9 · H2O and Crystal Structure of (NH4)4Mo2Br8

Iron(III) Complexes with Ethylene Diamine Tetraacetic Acid or Nitrilotriacetic Acid and Phenol Quarternary complexes of iron(III) with phenol (HR) and ethylene diamine tetraacetic acid (H₄Y) as well as nitrilotriacetic acid (H₃X) in aqueous solution could be detected. The equilibria have been controlled by spectrophotometric and electrophoretic methods. The measured optical properties and the equilibrium constants are discussed. The following particles are present : (see ?Inhaltsübersicht”?)
