1,4-Diazabicyclo[2.2.2]octane-1,4-diium bis(3-chlorobenzoate)

In the title salt C6H14N22+·2C7H4ClO2−, two 3-chlorobenzoate (3CBA) anions are bridged by one diprotonated 1,4-diazabicyclo[2.2.2]octane-1,4-diium (H2DABCO2+) dication through N—H...O hydrogen bonds. In this way, a trimeric unit is generated, in which the mean planes of the two 3CBA anions are twisted with respect to each other by a dihedral angle of 59.87 (9)°. The trimeric units are linked into a three-dimensional network via weak C—H...O interactions.
