Crystal and molecular structure of the saline complex hexaaquairon(II) hexachloroplatinate, [Fe(H2O)6][PtCl6]

In this work the structure of a hexachloroplatinate of a bivalent metal as iron with the formula FePtCl6 · 6 H2O is reported. The crystal contains [PtCl6]2– and [Fe(H2O)6]2+ ions adopting a regular octahedral coordination. A 3D hydrogen bond framework takes part in the cohesion of the structure paking anions and cations in like-chain structures along the c-axis. The structure can also be regarded as alternating Fe and Pt atomic planes stacking along the 001 and 011 directions. Taking advantage from this Fe and Pt arrangement, we propose the hydrogen reduction of FePtCl6 · 6 H2O crystallites as a new chemical strategy in the fabrication of FePt nanoparticle-based functional devices for advanced nanomagnetic applications.
