Bis(1,4-diazoniabicyclo[2.2.2]octane) di-μ-chlorido- bis[tetrachloridoantimonate(III)] dihydrate

Abstract

The title salt, (C6H14N2) 2[Sb2Cl10]·2H2O, was obtained by slow evaporation of an acidic solution of 1,4-diazabicyclo[2.2.2]octane and SbCl3. The crystal structure consists of (C6H 14N2)2+ cations, [Sb2Cl10] 4- double octahedra and lattice water molecules. All molecular components are situated on special positions. The cation and the lattice water molecule exhibit mirror symmetry, whereas the anion has site symmetry 2/m. The cations, anions and water molecules are alternately arranged into columns along [010]. Individual columns are joined into layers extending along (001). Intralayer N - H⋯O and interlayer N - H⋯Cl hydrogen-bonding interactions lead to the formation of a three-dimensional network. © Ben Rhaiem et al. 2013.
