New hydroxylammonium fluorometallates of manganese and scandium, with the formulas (NH3OH)2MnF4 and (NH 3OH)3ScF6, were prepared by the reactions of hydroxylammonium fluoride with solutions of manganese or scandium in aqueous HF. (NH3OH)2MnF4 crystallizes monoclinic, P2 1/c, the structure consisting of MnF6 octahedra sharing four of its vertices, resulting in [MnF42-]n anionic layers perpendicular to a axis. (NH3OH)3ScF 6 crystallizes trigonal, R3c, and the structure is made up of isolated ScF6 octahedra, stacked in columns along c axis and surrounded by a cylinder of hydroxylammonium cations. Both title compounds decompose during thermal analysis in several steps, yielding corresponding fluorides (MnF2 and ScF3) at temperatures between 300 and 400 °C and oxides/oxofluorides at higher temperatures.

This paper reports on the synthesis of a new hydroxylammonium fluoroferrate, with the formula (NH3OH)3FeF6, obtained after dissolving iron powder in hydrofluoric acid and adding solid NH3OHF. This new compound has been characterized by chemical and thermal analysis, single-crystal X-ray diffraction, and magnetic measurements. The title compound crystallizes trigonal, R3c, with cell parameters a = 11.4154(2) A, c = 11.5720(2) A, Z = 6. The structure consists of NH3OH+ cations and isolated FeF6 3- octahedra in which the central ion lies on a threefold axis. The oxygen and nitrogen atoms of the hydroxylammonium cations are donors of hydrogen bonds to fluoride anions, resulting in a network of hydrogen bonds between counterions. The effective magnetic moment μeff = 5.8 BM was calculated and perfectly matches the expected value of high-spin Fe(III) ions. The thermal decomposition of the compound was studied by TG, DSC, and X-ray powder diffraction.

The reactions of perchloryl fluoride and dichlorine heptoxide with low-molecular amines containing additional functional groups such as OH, NO2, NH2, or CO, are studied. The reactions of ClO3F and Cl2O7 with these amines proceed in two paths: the formatio
