C. A. Bremner and W. T. A. Harrison

Abstract: The title compound, (C₆H₁₄N₂)[NiCl₃(H₂O)₃]Cl·H₂O, contains doubly protonated 1,4-diazoniabicyclo[2.2.2]octane (dabconium) (C₆H₁₄N₂)²⁺ cations, mer-[Ni^II(H₂O)₃Cl₃]^- octahedra, [mean Ni-O  =  2.054  (2)  Å and mean Ni-Cl  = 2.4272  (6)  Å] and additional (non-coordinated) chloride ions and water molecules. These species interact by way of numerous O-HO, O-HCl and N-HCl hydrogen bonds and possible C-HCl interactions [mean HCl  = 2.75  Å, mean CCl  =  3.575  (3)  Å and mean C-HCl  = 142°] to result in a structure with a layered character. (C₆H₁₄N₂)[Ni(H₂O)₃Cl₃]Cl·H₂O is isostructural with its manganese(II)-containing congener.
