The enthalpy of formation of manganese tetrafluoride

Synthesis and Characterization of Manganese Tetrafluoride β‐MnF4

“…In the γ layers the V atoms are arranged in such a way, that each V atom is surrounded by six empty octahedral voids (Figure 3a). In this way, the V atoms span 3 6 nets parallel to (001) similar to the closed packed layers constituted by the F atoms but with an edge length scaled up by a factor of √3.…”

“…[5] In 1980 its enthalpy of formation was investigated. [6] In 1986, one hundred years after the discovery and successful isolation and characterization of elemental fluorine by Henry Moissan, [7] Karl Otto Christe succeeded in the chemical synthesis of elemental fluorine by thermal decomposition of MnF 4 prepared by starting materials that cupied in the VF 3 structure, are grouped together in the shape of a "star" with approximate D 3h symmetry. We prepared β-MnF 4 photochemically according to the literature and obtained a phase-pure powder as evidenced by X-ray diffraction at room temperature.…”

“…For M = Mn, the formation of MnF 4 was reported . In 1980 its enthalpy of formation was investigated . In 1986, one hundred years after the discovery and successful isolation and characterization of elemental fluorine by Henry Moissan , Karl Otto Christe succeeded in the chemical synthesis of elemental fluorine by thermal decomposition of MnF 4 prepared by starting materials that needed no F 2 in their respective production .…”
