Mangan(III) fluorida (juga dikenal sebagai Mangan trifluorida ) adalah senyawa anorganik dengan rumus MnF3. Padatan merah/keunguan ini digunakan untuk mengubah hidrokarbon menjadi fluorokarbon, yaitu zat fluorinasi.[1] Ini membentuk hidrat dan banyak turunannya.
Sintesis, struktur, dan reaksi
MnF3 dapat dibuat dengan mereaksikan larutan MnF2 dalam hidrogen fluorida dengan fluor:[2]
- MnF2 + 0.5 F2 → MnF3
Ini juga dapat dibuat dengan mereaksikan unsur fluorin dengan mangan(II) halida pada ~250 °C.[3]
Struktur
Seperti vanadium(III) fluorida, MnF3 menampilkan pusat logam oktahedral dengan jarak ikatan MF rata-rata yang sama. Namun, dalam senyawa Mn, terdistorsi (dan karenanya sel satuan monoklinik dengan sel simetri yang lebih tinggi) karena efek Jahn-Teller , dengan pasangan jarak Mn-F 1,79, 1,91, 2,09 Å.[4][5][6]
Hidrat MnF3.3H2O diperoleh dengan kristalisasi MnF3 dari asam fluorida. Hidrat tersedia sebagai dua polimorf, dengan grup ruang P21/c dan P21/a. Masing-masing terdiri dari garam Mn(H2O)4F2]+[Mn(H2O)2F4]− ).[7]
Reaksi
MnF3 bersifat asam Lewis dan membentuk berbagai turunan. Salah satu contohnya adalah K2MnF3(SO4).[8] MnF3 bereaksi dengan natrium fluorida menghasilkan heksafluorida oktahedral:[3]
- 3NaF + MnF3 → Na3MnF6
Reaksi terkait garam dari anion MnF52− atau MnF4−. Anion ini masing-masing mengadopsi struktur rantai dan lapisan, dengan menjembatani fluorida. Mangan tetap 6 koordinat, oktahedral, dan trivalen di semua bahan ini.[3]
Mangan(III) fluorida memfluorinasi senyawa organik termasuk hidrokarbon aromatik,[9] siklobutena,[10] dan fullerena.[11]
Saat pemanasan, MnF3 terurai menjadi mangan(II) fluorida.[12][13]
MnF3 merupakan sumber kompleks MnCl3 melalui reaksi dengan bismut triklorida.[14]
