Dưới đây là nguyên văn gốc cho các nguồn tham khảo tương ứng và một số thông tin bổ sung, trong đó […] là phần nội dung không cần thiết. Nếu cách ký hiệu này đứng ở vị trí đầu tiên hoặc cuối cùng, tức là trước (hoặc sau) đó vẫn còn nội dung.

  1. 1 2 3 Trang 68: Перхлорат Mn(II) был приготовлен смешиванием стехиометрических количеств химически чистых MnSO4 и Ba(OH)2 в избытке HClO4. К полученому раствору Mn(ClO4)3 добавляли подкисленный раствор KMnO4 с таким расчетом, чтобы обеспечить 20—30-кратный избыток Mn(III). При этом образуется коричневый раствор Mn(ClO4)3.
  2. ↑ Trang 68: Трехвалентный марганец готовили по методу Россейнского [1], используя реакцию 4Mn2+ + MnO4− + 8H+ → 5Mn3+ + 4H2O.
  3. ↑ Trang 1182: Thus, manganese(III) perchlorate solutions of concentration not exceeding about 10⁻³ M were prepared by addition of acid permanganate solution to sufficient acidified manganese(II) to leave finally a 25-fold excess of the latter ion in ~ 4M-acid. These solutions were usually stable for days, even when subsequently diluted so that the hydrogen-ion concentration became about 1.5 M. However, when the solutions were warmed at 50°, after for 90 minutes an appreciable amount of manganese dioxide precipitated. Even at room temperature the manganese(III) solutions are, in fact, metastable.
  4. ↑ Trang 49: […] and pyridine N-oxide and antipyrine complexes of manganese(III) perchlorate of the composition [MnL6](ClO4)3 are prepared and their structures assigned.
