Ethane-1,2-diaminium 2,2'-[tereph­thal­oyl­bis(aza­nedi­yl)]di­acetate tetrahydrate

Abstract top

In the title salt hydrate, C2H10N22+·C12H10N2O62-·4H2O, each of the ions is located about a centre of inversion and the asymmetric unit is completed by two water molecules in general positons. In the crystal, the cations, anions and water mol­ecules are connected by O-H...O and N-H...O hydrogen bonding into a three-dimensional network.

Comment top

Recently, the inter­est in constructing metal-organic coordination polymers continuously rises due to their facinating structures and properties with potential application as functional materials. For the synthesis of such compounds frequently relatively rigid ligands with several coordination centers are used. In this context the title compound was prepared, which should be used as a precursor in the synthesis of new coordination polymers.

The crystal structure of the title compound consists of 2,2'-(terephthaloylbis(aza­nediyl))di­acetate anions that are located on centers of inversion as well as of ethyl­enediaminium cations and water molecules in general positions (Fig. 1). The ethyl­enedi­amine cations are connected to the anions by N—H···O hydrogen bonding between the carboxyl­ate O atom and the ammonium H atoms. The anions and cations are additionally linked to water molecules via N—H···O and O—H···O hydrogen bonding into a three-dimensional network (Fig. 2 and Table 1). Furthermore, the compound shows luminescence under excitation with ultraviolet light.

Experimental top

The starting material, 2,2'-(benzene-1,4-dicarboxamido)­diacetatic acid, was prepared by the method of Cleaver & Pratt (Cleaver & Pratt, 1955). Single crystals were obtained by slow evaporation from an aqueous solution (40 ml) of 2,2'-terephthaloylbis-(glycine) dihydrate (630 mg) and ethyl­enedi­amine (3 ml) at room temperature. Colorless block shaped crystals appeared after a few days.

Refinement top

All hydrogen atoms were located the difference Fourier map and were refined isotropically with no restraints.

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.
