Abstract: In the title compound, {(C4H12N2)2[Li2(P6O18)]·4H2O}n, the phosphate ring anion, located around an inversion center, adopts a chair conformation. Adjacent P6O18 rings are linked via corner-sharing by LiO4 tetrahedra, generating anionic porous {[Li2(P6O18)]4-}n layers parallel to (101). The piperazine-1,4-diium cations occupy the pores and develop hydrogen bonds with the inorganic framework. An extensive network of N-H...O and O-H...O hydrogen-bonding interactions link the components into a three-dimensional network and additional stabilization is provided by weak C-H...O hydrogen bonds.
