title: 1,4-Diazabicyclo[2.2.2]octane-1,4-diium trichromate.
abstract: The title compound, (C(6)H(14)N(2))[Cr(3)O(10)], consists of a diazabicyclo[2.2.2]octane-1,4-diium cation and a discrete trichromate anion linked by an N-H.O hydrogen bond. Three CrO(4) tetrahedra are joined via shared O atoms to form the trichromate anion. Supramolecular rings, which can be described by the graph-set motif R(4)(4)(26), are built via N-H.O hydrogen bonds, and C-H.O interactions play lesser roles in forming the structure.
