Europium(III) iodida adalah sebuah senyawa anorganik yang mengandung europium dan iodin dengan rumus EuI
3.[1]
Pembuatan
[sunting | sunting sumber]Logam europium bereaksi langsung dengan iodin untuk membentuk europium(III) iodida:[5]
- 2 Eu + 3 I
2 → 2 EuI
3
Europium(III) iodida terhidrasi dapat dibuat dengan melarutkan europium(III) oksida atau europium(III) karbonat dalam asam iodida:[1][6]
- Eu
2O
3 + 6 HI + 6 H
2O → 2 EuI
3 · 9H2O
Bubuk europium bereaksi dengan iodin dalam THF untuk membentuk aduk THF dari europium(III) iodida:[7][8]
- 2 Eu + 3 I
2 + 7 THF → [EuI
2(THF)
5][EuI
4(THF)
2]
Aduk ini dapat dirumuskan lebih sederhana sebagai EuI3(THF)3,5.
Struktur
[sunting | sunting sumber]Europium(III) iodida mengadopsi jenis struktur kristal bismut(III) iodida (BiI3),[3][4] dengan koordinasi oktahedral dari setiap ion Eu3+ oleh 6 ion iodida.[1]
Reaktivitas
[sunting | sunting sumber]Europium(III) iodida digunakan sebagai bahan awal untuk dua cara utama pembuatan europium(II) iodida:[9]
Reduksi dengan gas hidrogen pada suhu 350 °C:
- 2 EuI
3 + H
2 → 2 EuI
2 + 2 HI
Dekomposisi termal[1] pada suhu 200 °C, reaksi disproporsionasi:
- 2 EuI
3 → 2 EuI
2 + 2 I
2
Europium(III) iodida nonahidrat, EuI3·9H2O, terurai secara termal menjadi europium(II) iodida dihidrat, EuI2·H2O.[10]
