In the crystal structure of the title compound, C₆H₉N₂⁺·ClCH₂COO⁻, prepared by the reaction of OPDA (orthophenelynediamine) with chloroacetic acid, N—H

O hydrogen bonds generate ladder-like chains and very weak intermolecular C—H

Cl hydrogen-bonding interactions between the anions and cations lead to a supramolecular network. C—H

O interactions also occur.

Comment top

We have reported here the synthesis and structural characterization of a hitherto unknown organic ion pair compound 1, consisting of orthophenylenediammonium cation and chloroacetate anion, that provides a good supramolecular information. The ladder-type one-dimensional chainlike arrangement has been generated because of N—H···O hydrogen bonding interaction in the crystal of compound 1, as shown in Fig. 3.

Experimental top

OPDA (Orthophenelynediamine)(0.108 g, 1 mmol) was dissolved in 20 ml of acetonitrile solution and which was added the solution of 25 ml of methanol containing chloroaceticacid (0.23 g, 1 mmol); this reaction mixture was stirred for 5 min and kept for crystalization at room temperature. Colorless needle-like crystals were formed after 3 days (yield: 0.145 g, 72% based on OPDA).

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.
