The 14H13N2+·C10H4O82−·2C14H12N2·C10H6O8, comprises a 2,9-dimethyl-1,10-phenanthrolin-1-ium cation (Me2PhenH+) and a 2,9-dimethyl-1,10-phenanthroline molecule (Me2Phen), each in a general position, and half each of a 2,5-dicarboxybenzene-1,4-dicarboxylate dianion (LH22−) and a benzene-1,2,4,5-tetracarboxylic acid molecule (LH4), each being disposed about a centre of inversion. Small twists are evident in the dianion [the C—C—C—O torsion angles are 168.41 (18) and 16.2 (3)°], whereas a major twist is found for one carboxylic acid group in the neutral molecule [C—C—C—O = 66.3 (2) and 18.2 (3)°]. The most prominent feature of the crystal packing is the formation of linear supramolecular chains along [001] mediated by charge-assisted O—H⋯O− hydrogen bonding between alternating LH4 and LH22−. These are connected to the Me2PhenH+ and Me2Phen species by N—H⋯O and O—H⋯N hydrogen bonds, respectively. A three-dimensional architecture is formed by C—H⋯O and π–π interactions [inter-centroid distance = 3.5337 (17) Å].

Crystals of (I) were obtained by the co-crystallization of benzene-1,2,4,5-tetracarboxylic acid (Sigma-Aldrich), 0.06 mmol) and 2,9-dimethylphenanthroline (ACROS, 0.09 mmol) in ethanol solution. Crystals were obtained by slow evaporation.
C-bound H-atoms were placed in calculated positions (C—H = 0.95–0.98 Å) and were included in the
in the riding model approximation with Uiso(H) set to 1.2–1.5Ueq(C). The O-and N-bound H-atoms were located in a difference Fourier map and were refined with a distance restraints of O—H = 0.84±0.01 Å and N—H = 0.88±0.01 Å, and with Uiso(H) = 1.2Ueq(N) and 1.5Ueq(O). Owing to being affected by the beam-stop, three reflections, i.e. (0 0 1), (1 0 1) and (-6 0 2), were omitted from the final cycles of refinement.Data collection: CrystalClear (Molecular Structure Corporation & Rigaku, 2005); cell

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

In continuation of on-going structural studies of salts/co-crystals formed between carboxylic acids and various pyridyl derivatives (Arman et al., 2010; Arman & Tiekink, 2013), the title salt co-crystal, (I), was isolated from the 2:3 co-crystallization of benzene-1,2,4,5-tetracarboxylic acid (LH4) and 2,9-dimethyl-1,10-phenanthroline (Me2Phen).
The asymmetric unit of (I) comprises a centrosymmetric, doubly deprotonated LH22- dianion, a centrosymmetric neutral LH4 molecule, a protonated Me2PhenH+ cation and a neutral Me2Phen molecule, Fig. 1, and is formulated as a combination of a 2:1 Me2Phen+:LH22- salt combined with a 2:1 Me2Phen:HL4 co-crystal. A salt formed between Me2PhenH+ and a hydrogen(S,S)-tartrate has been reported (Derikvand & Olmstead, 2011).
Small twists are evident in the LH22- dianion as seen in the C2—C1—C4—O2 and C1—C2—C5—O4 torsion angles of 168.41 (18) and 16.2 (3)°, respectively. This arrangement is stabilized by intramolecular O—H···O hydrogen bonds, Table 1. By contrast, a considerable twist is evident in LH4 with the C7—C6—C9—O6 and C6—C7—C10—O7 torsion angles being 66.3 (2) and 18.2 (3)°, respectively. Such variations in conformation have been discussed in some detail (Arman & Tiekink, 2013). The Me2Phen molecule and Me2PhenH+ cation are each planar with the r.m.s. deviation for the 16 non-hydrogen atoms being 0.037 and 0.036 Å, respectively.
The prominent feature of the crystal packing is the formation of linear supramolecular chains along [0 0 1] comprising alternating LH4 and LH22- species connected via charge-assisted O6—H···O2 hydrogen bonding, Table 1. The hydroxyl-O8 forms an O—H···N4 hydrogen bond with the neutral Me2Phen molecules, one to either side of the carboxylic acid/carboxylate chain. The O3,O4 carboxylic acid residue accepts hydrogen bonds from the N1—H1n atom of the Me2PhenH+ cation, again, from symmetry, one to either side, leading to the supramolecular chain shown in Fig. 2a; an end-on view is shown in Fig. 2b. The Me2Phen and Me2PhenH+ cations inter-digitate along the c axis and are connected by π—π [Cg(C15–C20)···Cg(C29—C34)i = 3.5337 (17) Å for i: x, 1 + y, z] interactions between Me2PhenH+ and Me2Phen. Additional contacts are of the type C—H···O, Table 1, as illustrated in the crystal packing diagram, Fig. 3.
