4-aza-1-azoniabicyclo[2.2.2]octane dihydrogenphosphite

The title compound, C6H13N+.H2PO3-, contains monoprotonated 4-aza-1-azoniabicyclo[2.2.2] octane (dabconium, C6H13N+) cations and dihydrogenphosphite (H2PO3-) anions. The H2PO3- units are linked into a polymeric chain by P-O-H...O-P hydrogen bonds in the [100] direction. The dabconium cations are pendant to the dihydrogenphosphite chains by way of N-H...O hydrogen bonds and possible C-H...O interactions. The chains are crosslinked by means of van der Waals forces.
