Bis(6-nitro-1,10-phenanthrolin-1-ium) 2,5-dicarboxyterephthalate

In the structure of the title 2:1 proton-transfer compound, 2C₁₂H₈N₃O₂⁺·C₁₀H₄O₈²⁻, the 6-nitro-1,10-phenanthroline molecules act as proton sponges, accepting protons from pyromellitic acid. The –NO₂ group of one of the 6-nitro-1,10-phenanthrolin-1-ium cations is disordered and was refined with a site-occupancy ratio of 0.624 (15):0.376 (15). Two –COOH(–COO⁻) groups of the 2,5-dicarboxyterephthalate dianion are disordered and were refined with site-occupancy ratios of 0.769 (4):0.231 (4) and 0.766 (5):0.234 (5). The –NO₂ group of the second cation is also disordered about a pseudo-twofold rotation axis and was refined with a site-occupancy ratio of 0.903 (3):0.097 (3). There is an intramolecular O—H

O hydrogen bond in the anion. The phenanthroline rings of the two cations are inclined to one another by 31.3 (1)°. In the anions, considering the major components only, the carboxylic acid groups (–COOH) are inclined to the benzene ring by 17.3 (2) and 22.3 (3)°. The carboxylate groups (–COO⁻) are twisted by 9.3 (2) and 13.6 (6)° with respect to the benzene ring. In the crystal, adjacent 2,5-dicarboxyterephthalate anions are linked via O—H

O hydrogen bonds, forming chains propagating along [010]. The cations are attached to the chain of anions by N—H

O hydrogen bonds.

Comment top

Pyromellitic (PMA) acid (Li et al., 2003; Fabelo et al., 2008) has been widely use in constructing interesting supramolecular networks because it can act not only as an hydrogen bond acceptor but also as an hydrogen bond donor, depending upon the number of deprotonated carboxylate groups present. Proton-transfer compounds of PMA with 1,10-phenanthroline for example 1,10-Phenanthrolinium trihydrogen-1,2,4,5-benzenetetracarboxylate monohydrate [Guo et al., 2007] and a substituted phenanthroline 2,9-Dimethyl-1,10-phenanthrolin-1-ium 2,4,5-tricarboxybenzoate monohydrate [Zhong, 2013] have been synthesized and reported. The title compound was obtained using PMA and 6-nitro-1,10-phenanthroline, via a thermal reaction and we report herein on its crystal structure.

The asymmetric unit of the title compound consists of two 6-nitro-1,10-phenanthrolin-1-ium cations, one 2,5-dicarboxyterephthalate anion, Fig. 1. The proton transfer is from two carboxyl groups to the ring N atoms (N3 and N6) of the 5-nitro-1,10-phenanthroline cations. In the anion, the dihedral angles between the benzene ring of PMA^2- and the mean-planes of the COOH (COO^-) groups are 17.3 (2) ° for (O5/C25/O6), 22.3 (3) ° for (O9/C31/O10), 13.6 (6) ° for (O7/C28/O8) and 9.3 (2)° for (O11/C33/O12). An intramolecular O—H···O hydrogen bond is observed in the anion (Fig. 1 and Table 1).

In the crystal, adjacent PMA^2- anions interact via O—H···O hydrogen bonds, forming one-dimensional chains along the b axis, and the 6-nitro-1,10-phenanthrolin-1-ium cations are attached to the PMA^2- anions by N—H···O hydrogen bonds (Fig. 2 and Table 1).

Experimental top

0.1 mmol 5-nitro-1,10-phenanthroline, 0.1 mmol 1,2,4,5-benzenetetracarboxylic acid, and 2.0 ml water were mixed and placed in a thick Pyrex tube, which was sealed and heated to 383 K for 72 h, whereupon pink block-shaped crystals of the title compound were obtained.

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.
