Bis(4-ethoxy­anilinium) sulfate trihydrate

Abstract

The structure of the title compound, 2C8H12NO+·SO4 2−·3H2O, consists of organic layers, water mol­ecules and SO4 2− anions which lie within the organic layers. In the crystal, inter­molecular N—H(...)O, N—H(...)S O—H(...)O and O—H(...)S hydrogen bonds, some of which are bifurcated, stabilize the structure.

Comment

This study is a part of systematic investigation of dielectric-ferroelectric materials, including organic ligands (Li et al., 2008), metal–organic coordination compounds (Hang et al., 2009) and organic–inorganic hybrid. 4-Ethoxyanilinium perchlorate has no dielectric disuniform from 80 K to 480 K, (m.p. 492–493 K).

The asymmetric unit of the title compound contains two 4-ethoxyanilinium cations, one sulfate radical anion and three water molecules (Fig 1). In the anion, the torsion angles of C1—C2—O5—C3 and C9—C10—O6—C11 are -174.8 (2)° and 179.48 (19)°, respectively. The supramolecular structure consists of infinite chains of anions with one cation and three water molecules linked to each anion via N—H···O and O—H···O hydrogen bonds.

Experimental

Single crystals of 4-ethoxyanilinium sulfate are prepared by slow evaporation for five days at room temperature of an ethanol solution of 4-ethoxybenzenamine and sulfuric acid (5 mol l-).

Refinement

Positional parameters of all the H atoms were calculated geometrically and were allowed to ride on the C atoms to which they are bonded, with Uiso(H) = 1.2Ueq(C).

Special details

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.
