在六水合Sepulchrate磷酸二氢钴（III）（Sepulchrate = 1，3，6，8，10，13，16，19-八氮杂双环[6.6.6]二十烷）[Co（C12 H30 N8）]（H2 P3 O 10）·6 H2O中，阳离子采用lel 3 [Δ（λ）]光学活性构象。阳离子的总体几何形状与其他盐中发现的没有显著不同。一个强对称的O H O氢键是负离子的环状构象的原因，其几何形状被描述为一个八元皱环。整个晶体堆积由氢键控制。阳离子和阴离子在具有六元网格的三维网络中连接在一起;水分子位于空隙中，并且仅与阴离子相互作用。
In cobalt(III) sepulchrate dihydrogenphosphate hexahydrate (sepulchrate = 1,3,6,8,10,13,16,19-octaazabicyclo[6.6.6]icosane), [Co(C12H30N8)](H2P3O10).6H2O, the cation adopts the lel3 [Δ(λλλ)] optically active conformation. The overall geometry of the cation is not significantly different from that found in other salts. A strong symmetric O⋯H⋯O hydrogen bond is responsible for the cyclic conformation of the anion, whose geometry is described as an eight-membered puckered ring. The entire crystal packing is dominated by hydrogen bonds. The cations and the anions are linked together in a three-dimensional network with six-membered meshes; the water molecules are situated into the voids, and interact only with the anions.
