نویسندگان
چکیده
The asymmetric unit of the title salt, C(4)H(12)N(2) (2+)·2C(9)H(5)O(6) (-), comprises one half of the piperazine-1,4-diium dication lying on an inversion centre and one 3,5-dicarboxy-benzoate anion. In the crystal, the ions are linked into a two-dimensional framework parallel to (101) by N-H⋯O and O-H⋯O hydrogen bonds.

In the title hydrated mol-ecular salt, C(6)H(16)N(2) (+)·2PF(6) (-)·2H(2)O, the complete 1,4-dimethyl-piperazine-1,4-diium dication is generated by crystallographic inversion symmetry and both C-N bonds are in equatorial orientations. In the crystal, the components are linked by O-H⋯F and N-H⋯O hydrogen bonds but there are no direct links between cations and anions.

In the title compound, C(10)H(16)N(2) (2+)·2HSO(4) (-), the S atoms adopt slightly distorted tetra-hedral geometry and the diprotonated piperazine ring adopts a chair conformation. In the crystal, the 1-phenyl-piperazine-1,4-diium cations are anchored between chains formed by the sulfate entities via inter-molecular bifurcated N-H⋯(O,O) and weak C-H⋯O hydrogen bonds. These hydrogen bonds contri...

The asymmetric unit of the organic-inorganic title salt, (C10H28N4)[Cr2O7]2, comprises one half of an 1,4-bis-(3-ammonio-prop-yl)piperazinediium cation (the other half being generated by the application of inversion symmetry) and a dichromate anion. The piperazine ring of the cation adopts a chair conformation, and the two CrO4 tetra-hedra of the anion are in an almost eclipsed conformation. In...

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 tetra-hedra, 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 framewor...
