Teknesium(VII) sulfida merupakan senyawa kimia anorganik biner dari logam teknesium dan belerang dengan rumus kimia Tc2S7.[1][2][3][4]
Sintesis
Melewatkan hidrogen sulfida melalui larutan perteknetat asam akan menghasilkan teknesium(VII) sulfida:[5][6][7]
- 2KTcO4 + 7H2S + 2HCl → Tc2S7↓ + 2KCl + 8H2O
- 2NH4TcO4 + 7H2S + 2HCl → Tc2S7↓ + 2NH4Cl + 8H2O
Sifat kimia
Teknesium(VII) sulfida direduksi oleh hidrogen pada suhu 1000 °C:
- Tc2S7 + 7H2 → 2Tc + 7H2S
