(Received 24 September 2010; accepted 28 October 2010; online 6 November 2010)

In the crystal of the title hydrated molecular salt, 2C3H12N22+·C10H2O84−·2H2O, the packing is stabilized by extensive N—H⋯O and O—H⋯O hydrogen-bonding inter­actions involving all three species, forming a supra­molecular three-dimensional structure. The tetraanion is generated by inversion.

Several proton transfer systems using benzene- 1,2,4,5-tetracarboxylic acid (H4BTC), with nitrogen donor molecules, such as 1,10-phenanthroline, 1,7-phenanthroline, phenazine, 4-(N,N-dimethylamino)pyridine, 1,2-bis(4-pyridyl) ethene and 1,2-bis(4-pyridyl)ethane, have been synthesized and characterized by X-ray diffraction methods (Aghabozorg et al. 2008, Arora & Pedireddi, 2003). R%elated crystal structures of (H2BTC)(Hphen)2- (H4BTC) (where phen is 1,10-phenanthroline; Wang et al., 2005), (H3BTC)(Hbipy).3H2O (where bipy is 2,20-bipyridine; Ma et al., 2005), (H2BTC)(Hbipy)2(H4BTC) (Mrvos-Sermek et al., 1996) and (BTC)(H2en)2.2H2O (Rafizadeh et al. 2006) have been reported previously.

In the title compound, (C3H12N2)22+ (C10H2O8)4-. 2H2O, the asymmetric unit contains two diprotonated propane-1,2-diamine cations, one tetraanionic deprotonated anion form of benzene-1,2,4,5-tetracarboxylic acid and two water molecules (Fig. 1). The dication forms from the transfer of a single proton from each of the carboxyl groups to a propane-1,2-diamine molecule. The negative charges of one of the tetraanionic 1,2,4,5-benzenetetracarboxylate groups, is thereby neutralized by a doubly protonated propane-1,2-diammonium fragment. Crystal packing is stabilized by extensive N—H···O and O—H···O hydrogen bonding interactions involving all three species forming a supramolecular 3-D structure (Fig. 2).

Experimental top

Propane-1,2-diamine (12.6 mmol) was added to a solution of benzene-1,2,4,5-tetracarboxylic acid (1.65 g, 6.3 mmol) in ethanol (30 ml) at room temperature. The milky precipitated product was recrystallized from water. After one week, colorless plate crystals of (I) were isolated (yield 87.1%, decomposition < 420 K)

Refinement top

All of the H atoms were placed in their calculated positions and then refined using the riding model with Atom—H lengths of 0.93, 0.98Å (CH), 0.97Å (CH2) 0.96Å (CH3) or 0.89Å (NH). Isotropic displacement parameters for these atoms were set to 1.5 times (NH), 1.2 (CH, CH2, CH3) times Ueq of the parent atom. Water H atoms atoms were located in a difference Fourier map and refined isotropically without restraint.

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.
