↑ Trang 1200: Гексагидрат перрената хрома хорошо растворим в воде, спирте, ацетоне и нерастворим в четыреххлористом углероде. Плотность исходного кристаллогидрата перрената хрома, определен ная пикнометрическим методом, оказалась равной 3,40 г/см³ при 25 ℃.
↑ Trang 2: W 2009 r. Mikhailova i współpracownicy uzyskali ten sam związek poprzez reakcję świeżo strąconego tlenku chromu(III) z kwasem renowym(VII).
↑ Trang 1199: В результате взаимодействия раствора рениевой кислоты с гидроокисью хрома, взятых в стехиометрическом соотношении, образуется зеленый раствор с рН 2—3, который упаривали пад СаСl2 до постоянной Массы. Через несколько суток из раствора выпадали кристаллы зеленого цвета, характерного для иона трехвалентного хрома.

1 2 Trang 381: The thermal stabilities of the perrhenates decrease in the order: Mn > Co > Ni > Fe > Cr.
↑ Trang 380: The first stage of the thermal decomposition of Cr(III) perrhenate was observed at 450-480 ℃; to it there corresponds a relative small rise in intensity I (first MTA peak). The loss in weight here is small: about 5%.
↑ Trang 380: In the second stage (650-700 ℃) we have the highest intensity I and the greatest loss in weight (about 80%). The residue consists mainly of Cr2O3 and ReO2. At temperatures of 870-1000 ℃ we again observe a small rise in I and a small loss in weight. The final decomposition product consists of Cr2O3, and metallic rhenium.
↑ Trang 380: […] after these perrhenates had been heated until no more dirhenium heptaoxide came off exceeded the weight of the oxides M2O3 formed in the following reaction by 50-60%: 2M(ReO4)3 → M2O3 (solid) + 3Re2O7 (gas).
↑ Trang 1201 cũng có bảng tương tự, nhưng bản gốc có thêm phần mô tả.
↑ Trang 1285: The compounds are bright green, with the dihydroxide per-rhenate having the darker tint. The pyknometric densities of chromium(III) hydroxide bisper-rhenate tetrahydrate and dihydroxide per-rhenate dihydrate at (25 ± 0.1) ℃ are 3.11 and 2.88 g cm³ respectively.
↑ Trang 1285: Both the crystalline hydrates are dehydrated in two stages via intermediate hydrates Cr(OH)(ReO4)2·2,5H2O and Cr(OH)2(ReO4)·H2O. During this process the colour of the compounds changes from bright green through dark green to dirty marsh-coloured.
