The title hydrated salt, tris-[hexa-amminecobalt(III)] tetraoxidorhenate(VII) tetra-kis-[hexa-fluorido-rhenate(IV)] hexa-hydrate, arose unexpectedly due to possible contamination of the KReF starting material with KReO. It consists of octa-hedral [Co(NH)] cation (Co1 site symmetry 1), tetra-hedral [ReO] anions (Re site symmetry 1) and octa-hedral [ReF] anions (Re site symmetries 1and ). The [ReF] octa-hedral anions (mean Re-F = 1.834 Å), [Co(NH)] octa-hedral cations (mean Co-N = 1.962 Å), and the [ReO] tetra-hedral anion (mean Re-O = 1.719 Å) are slightly distorted. A network of N-H⋯F hydrogen bonds consolidates the structure. The crystal studied was refined as a two-component twin.
标题水合盐，三[六氨合钴(III)] 高铼酸根(VII) 四[六氟铼酸根(IV)] 六水合物，由于起始原料KReF可能被KReO污染而意外产生。它由八面体[Co(NH₃)₆]³⁺阳离子（Co1位点对称性1）、四面体[ReO₄]⁻阴离子（Re位点对称性1）和八面体[ReF₆]²⁻阴离子（Re位点对称性1和 ）组成。[ReF₆]²⁻八面体阴离子（平均Re-F = 1.834 Å）、[Co(NH₃)₆]³⁺八面体阳离子（平均Co-N = 1.962 Å）和[ReO₄]⁻四面体阴离子（平均Re-O = 1.719 Å）略有畸变。N-H⋯F氢键网络巩固了结构。所研究的晶体被精修为双晶。
