Bis(3-hydroxypropanaminium) naphthalene-1,5-disulfonate

Y. Jin

Abstract top

In the title molecular salt, 2C3H10NO+·C10H6O6S22-, the cations and anions are associated via N-H...O and O-H...O hydrogen-bonding interactions, giving rise to a three-dimensional structure with zigzag rows of cations lying between rows of anions. The asymmetric unit contains one cation and one half-anion, which is related to the remainder of the molecule by an inversion center.

Comment top

Ferroelectric compounds have displayed such technical applications as ferroelectric random access memories (FeRAM), ferroelectric field-effect transistors, infrared detectors, piezoelectric sensors, nonlinear optical devices due to their excellent ferroelectric, piezoelectric, pyroelectric, and optical properties. A large number of new ferroelectric metal-organic coordination compounds corresponding to the necessary requirements for ferroelectric properties have been found, yet other necessary conditions, such as a phase transition, a good electric hysteresis loop and electric domain, and a dielectric anomaly, are often missed (Zhang et al., 2009). Therefore pure organic compounds are of great potential and can make up for the drawbacks found in ferroelectric metal-organic coordination compounds. Reversible phase transitions remain one of the prominent properties for ferroelectrics. There exists a series of compounds in which the components can be arranged in a disordered fashion at a relatively high temperature and in an ordered fashion at a relatively low temperature and where the transition is reversible, which is called a reversible structual transition (Fu et al., 2009; Zhang et al., 2010; Zhang et al., 2008; Ye et al., 2006). The transition from the disordered arrangement to the ordered one leads to a sharp change in the physical properties of the compound. As part of our search for simple ferroelectric compounds I have investigated the title compound and report here its room temperature structure.

The centrosymmetric anion and one cation are shown in Fig. 1 with the hydrogen bonds listed in Table 1. The existence of numerous hydrogen-bonding interactions helps to make the substance more stable, so that it forms a three-dimensional layered structure. These interactions tie the cations and anions together in sheets with zigzag rows of cations lying between rows of anions (Fig. 2).

Experimental top

(C3H10NO)2.(C10H6O6S2) was formed from a mixture of NH2(CH2)3OH (150.2 mg, 2.00 mmol), C10H8O6S2 (288.28 mg, 1.00 mmol), and distilled water (10 ml), which was stirred a few minutes at room temperature, giving a clear transparent solution. After evaporation for a few days, block colorless crystals suitable for X-ray diffraction were obtained in about 78% yield and filtered and washed with distilled water.

Refinement top

H atoms bound to carbon and nitrogen were placed at idealized positions [C—H = 0.93–0.97 Å, O—H = 0.82 Å and N—H = 0.89 Å] and allowed to ride on their parent atoms with Uiso fixed at 1.2 Ueq(C,N).

Special details top

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.
