title: Topochemical Oxidation of Perovskite KCoF3 to a K2PtCl6 Structure-Type Oxyfluoride.
abstract: Oxyfluoride, K2CoOF4 with K2PtCl6 structure, has been stabilized from a perovskite-based KCoF3 complex by a simple oxidative anion insertion topochemical reaction. Similar structural transformations have been observed for Ni- and Mn-containing systems. The generation of such unusual compounds, by soft chemical methods, strengthens the efforts toward materials discovery.
