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 [[Delta]([lambda][lambda][lambda])] 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.
