A Facile Synthesis of Pure O2PtF6

A new and facile synthesis of O₂PtF₆ is reported without the demanding synthesis of PtF₆ or the use of high pressure fluorination in the presence of oxygen. The O₂PtF₆ is obtained in form of single crystals by direct Klemm‐type fluorination of commercially available PtO₂ · xH₂O in a stream of diluted F₂ of atmospheric pressure at a temperature of 275 °C. Its identity and purity was evidenced by powder X‐ray diffraction, Raman and infrared spectroscopy. The synthesis allows the preparation of pure dioxygenyl hexafluoridoplatinate(V). The new synthesis of O₂PtF₆ is deemed more convenient than those that require the extremely reactive PtF₆.
