Supra­molecular hydrogen-bonding networks in bis­(adeninium) phthalate phthalic acid 1.45-hydrate

In the title compound, 2C5H6N5+·C8H4O42−·C8H6O4·1.45H2O, the asymmetric unit comprises two adeninium cations, two half phthalate anions with crystallographic C2 symmetry, one neutral phthalic acid mol­ecule, and one fully occupied and one partially occupied site (0.45) for water mol­ecules. The aden...

Description
Summary:In the title compound, 2C5H6N5+·C8H4O42−·C8H6O4·1.45H2O, the asymmetric unit comprises two adeninium cations, two half phthalate anions with crystallographic C2 symmetry, one neutral phthalic acid mol­ecule, and one fully occupied and one partially occupied site (0.45) for water mol­ecules. The adeninium cations form N—H⋯O hydrogen bonds with the phthalate anions. The cations also form infinite one‐dimensional polymeric ribbons via N—H⋯N inter­actions. In the crystal packing, hydrogen‐bonded columns of cations, anions and phthalate anions extend parallel to the c axis. The water mol­ecules crosslink adjacent columns into hydrogen‐bonded layers.
