(Received 24 February 2011; accepted 28 February 2011; online 9 March 2011)

In the title compound, (C12H20N2)[ZnCl4]·H2O, the two piperazine N atoms are protonated and the [ZnCl4]2− anions adopt a slightly distorted tetra­hedral configuration. In the crystal, O—H⋯Cl hydrogen bonds link the tetra­chloridozincate anions and the water mol­ecules into corrugated inorganic chains parallel to [010]. The crystal structure is stabilized by N—H⋯Cl, N—H⋯O and O—H⋯Cl hydrogen bonds, with the N—H hydrogen bond originating from one of the two N atoms being trifurcated.

Comment top

Organic-inorganic hybrid materials continue to attract much attention due to their potential applications in various fields (Dai et al., 2002; Tao et al., 2003). In this work, we report the crystal structure of one such compound, [1-(2,5-(CH3)2C6H3)C4H11N2]ZnCl4.H2O. As shown in Fig. 1, the asymmetric unit consists of one 1-(2,5-dimethyphenyl)piperazine-1,4-diium dication doubly protonated at the N1 and N2 nitrogen atoms, one water molecule and one [ZnCl4]2- anion. The atomic arrangement of [1-(2,5-(CH3)2C6H3)C4H11N2]ZnCl4.H2O can be described as built up by corrugated inorganic chains of [ZnCl4]2- tetrahedra and water molecules that extend along the b axis, held together by O—H···Cl hydrogen bonds (Fig. 2, Table 1). Two such chains cross the unit cell at z = (2n +1)/4 and x = 1/2. The organic groups are located between these chains and connect to them through N—H···Cl and N—H···O hydrogen bonds to form a three dimensional infinite network (Fig. 3, Table 1). Among all the hydrogen bonds, one is trifurcated: N2—H2B···(Cl1, Cl4, O1). Within the network, the 1-(2,5-dimethylphenyl)piperazine-1,4-diium dications are arranged into antiparallel dimers. No π-π stacking interactions between the phenylene rings or C—H···π interactions towards them are observed. In the organic entity, the piperazine-1,4-diium ring adopts a typical chair conformation and all the geometrical features agree with those found in 1-(2,3-dimethylphenyl)piperazinium tetrachlorozincate(II) monohydrate (Ben Gharbia et al., 2007). It is worth noticing that in the [ZnCl4]2- anion, the Zn—Cl bond lengths and Cl—Zn—Cl bond angles are not equal to one another, but vary with the environment around the Cl atom with Zn—Cl bond lengths between 2.2619 (4) and 2.2857 (4) Å. In the title compound, all the chloride ions are involved in hydrogen bonding. However, only the Cl4 chloride atom participates in two N—H···Cl bonds, and the Zn1—Cl4 bond distance is with 2.2857 (4) Å the longest (Table 1). The Cl—Zn—Cl angles range between 105.803 (16) and 112.737 (17)°. These values indicate that the coordination geometry of the Zn atom can be regarded as being a slightly distorted tetrahedron (Harrison, 2005).

Experimental top

A mixture of an aqueous solution of 1-(2,5-dimethyphenyl)piperazine (2 mmol, 0.380 g), zinc chloride (2 mmol, 0.396 g) and HCl (10 ml, 0.4 M) in a Petri dish was slowly evaporated at room temperature. Single crystals of the title compound, suitable for X-ray diffraction analysis, were obtained after several days by slow evaporation at room temperature (yield 68%).

Refinement top

Reflection (0 0 1) was obscured by the beamstop and was omitted from the refinement. C—H hydrogen atoms were placed in calculated positions with C—H distances in the range 0.93–0.97 Å. The water hydrogen atom positions were refined with O—H distance restraints of 0.84 (2) Å, and the N—H distance of N1 to 0.91 (2) Å. The Uiso(H) values of all H atoms were constrained to 1.2 or 1.5 times Ueq of the respective 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.
