The title compound Bis(1,4-diazabicyclo[2.2.2]octane)octachlorido-di-bismuthate (III) dihydrate was obtained by slow evaporation at room temperature of a hydrochloric aqueous solution (pH=1) containing bismuth (III) nitrate and the 1,4-diazabicyclo[2.2.2]octane (DABCO) in a 1:2 molar ratio. This material crystallizes in the P21/c monoclinic space group with a=7.875(1)Å, b=18.380(2)Å, c=10.445(2)Å, β=105.95(1)° and Z=2.

The structure exhibits a zero-dimensional (0D) periodic arrangement of bioctahedra (Bi2Cl10)4- surrounded by organic cations 1,4-diazabicyclo[2.2.2]octane (DABCO). The crystal cohesion is achieved by N-H…Cl, N-H…O and O-H…Cl hydrogen interaction linking the different parts of the structure. This compound was characterized by different techniques such as IR, DSC, TGA-DTA, XRD, XPRD and photoluminescence (PL) at room temperature.
