In the title compound, 2C12H20N22+·2H3O+·P6O186−·2H2O, a protonated water mol­ecule bridges the centrosymmetrical anionic P6O18 ring via O—H⋯O hydrogen bonds. The centrosymmetric hydrogen-bonded rings formed by four oxonium cations and four phosphate anions can be described by an R48(36) graph-set motif. The ring motifs are connected by hydrogen bonds into inorganic layers perpendicular to [100]. The 1-(2,3-di­methyl­phen­yl)piperazine-1,4-diium cations are located between the layers, compensating their negative charge and establishing N—H⋯O hydrogen bonds with the O atoms of the anionic framework.

The literature reports several cyclohexaphosphates of organic cations and/or inorganic cations (Durif,1995). However, cyclohexaphosphates of mixed cations associating the oxoniumion are still relatively very limited. Up to now, only two examples have been known and structurally characterized (Amri et al., 2008, Marouani et al.,2010). In this work, we report the preparation and the structural investigation of a new organic oxonium cyclohexaphospohate, 2(C12H20N2)2+.2H3O+.P6O186-. 2H2O, (I), where the organic species is the piperazinium group. Piperazine derivatives have wide range of applications in pharmaceuticals as antimalarial (Kaur et al., 2010), anti-tuberculosis (Eswaran et al., 2010), antitumor (Chou et al., 2010), anticancer (Chen et al., 2004) and antiviral (Shingalapur et al., 2009) agents.

The asymmetric unit of (I) includes one-half of the P6O18 ring lying on an inversion center (1/2, 1/2, 0), one 1-(2,3-dimethylphenyl) piperazine-1,4-diium cation, one hydronium cation and one water molecule (Fig.1). As shown in Fig.2, the hydronium cations (OW2) bridge the anionic ring to form 2-D corrugated layers, located at x = 1/2 and parallel to the bc-plane. The result of these interactions is the formation of a 36-membered ring with an R48(36) graph-set motif (Bernstein et al., 1995). The centre of 36-membered ring is situated on a crystallographic centre of symmetry. Inside these layers, the phosphoric rings display a chair conformation with geometrical characteristics that show no significant difference in deviation from those observed in other cyclohexaphosphates having the same internal symmetry -1 (Amri et al., 2009; Abid et al., 2011; Ameur et al., 2013). The anchorage of the water molecule OW1 and the organic cations is made by short and long H-bonds, ensuring the interconnection between layers, and thus giving rise to a three-dimensional network. The benzyl ring (C5—C10) is essentially planar with an r.m.s. deviation of 0.0047 Å and is orientated at an angle of 54.09 (5)° with respect to the piperazine ring (Fig.3). The piperazine (N1–N2/C1–C4) ring adopts a chair conformation [puckering parameters: QT = 0.577 (2) Å, θ = 0.7 (2)° and ϕ = 326 (12) (Cremer & Pople, 1975)] with atoms N1 and N2 deviating by -0.683 (2) and 0.657 (2) Å from the least-squares plane defined by the remaining atoms in the ring. The interatomic bond lengths (C—C,N—C) and angles in (C—C—C,C—N—C) do not show significant deviation from those reported in a related 1-phenylpiperazine-1,4-diium salt (Ben Gharbia et al., 2005). An extensive network of N—H···O and O—H···O hydrogen-bonding interactions link the components of the structure into a three-dimensional network (Fig. 3).

Experimental top

Crystals of the title compound were prepared by adding dropwise an ethanolic solution (5 ml) of 1-(2,3)dimethlphenylpiperazine (4 mmol) to an aqueous solution (10 ml) of cyclohexaphosphoric acid (2 mmol). The reaction mixture was stirred at room temperature for few minutes. X-ray quality crystals of the title compound appeared after a few days. The cyclohexaphosphoric acid H6P6O18, was produced from Li6P6O18.6H2O, prepared according to the procedure of Schülke and Kayser (Schülke & Kayser, 1985), through an ion-exchange resin in H-state (Amberlite IR 120).

Refinement top

H1W1, H1W2, H2W1, H2W2 and H3W2 were located by Fourier maps and refined as riding in their as-found relative positions with Uiso(H) = 1.5Ueq(O). All remaining H atoms were placed in their calculated positions and then refined using the riding model with atom-H lengths of 0.93 Å (CH), 0.97 Å (CH2), 0.96 Å (CH3), 0.91 Å (NH) and 0.90 Å (NH3). Uiso were set to 1.2 (CH, CH2), 1.5 (CH3) or 1.20 (NH) times Ueq of the parent atom.

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
