The 20H14O4·2C2D6OS, contains half of the substituted terephthalic acid molecule and one solvent molecule. The centroid of the central benzene ring in the acid molecule is coincident with a crystallographic inversion center. Neither the carboxyl nor the phenyl substituents are coplanar with the central aromatic ring, showing dihedral angles of 53.18 (11) and 47.83 (11)°, respectively. The dimethyl sulfoxide solvent molecules are hydrogen bonded to the carboxylic acid groups.

The compound was prepared by a method described in the literature (Deuschel, 1951; Ebel & Deuschel, 1956), slighty modified by using d6-DMSO for crystallization instead of C6H5CN, giving the DMSO-clathrate. The title compound was prepared in a 93% yield, mp. = 280°C (dec).
The hydrogen atoms positions were calculated after each cycle of
with SHELXL (Bruker,1999) using a riding model, with C—H distances in the range of 0.93 to 0.96 Å. Uiso(H) values were set equal to 1.5Ueq of the parent carbon atom for methyl groups, and 1.2Ueq for the others. The carboxylic acid hydrogen atom was located in the difference Fourier map, and its coordinates were subsequentely kept fixed (by adding 10 to the coordinates in SHELXL), while Uiso(H) was left free to refine.2,5-Diphenyl-1,4-benzenedicarboxylic acid (2,5-Diphenylterephthalic acid) has been described previously as a precursor towards trans-fluorenacenedione, prepared by its dehydration with sulfuric acid (Ebel & Deuschel, 1956).
The compound has a central terephtalic acid core, substituted at positions 2 and 5 with phenyl groups. The molecule has been previoulsy described by Tanaka et al. (Tanaka et al., 2009) in the form of an ethanol solvate. Tanaka et al. also described a related compound where the phenyl groups were replaced by p-fluorophenyl groups, which crystallized as a dimethylformamide solvate.
The carboxylic acid and the phenyl groups are highly planar. They define dihedral angles of 53.18 (11)° and 47.83 (11)°, respectively, with the central aromatic ring. The corresponding values are 28.2 (2)° and 57.2 (1)°, and 115.3 (1)° and 46.3 (1)°, for both dihedral angles in the ethanol solvate, and in the p-fluoro compound, respectively.
The molecule has an inversion center (crystallographic) coincident with the centroid of the central ring, so the
symmetry of the isolated molecule is Ci. The same happens for the ethanol solvate and the p-fluoro compounds respectively.The packing shows a deuterated dimethyl sulfoxide solvent molecule hydrogen bonded with each carboxylic acid group, with O1···O3ii distance of 2.581 (2) Å (ii: x + 1, y, z). There are two molecules of solvent for a single diacid molecule, each one defining one of the aforementioned hydrogen bond with each carboxylic acid group. A closely related pattern occurs for the ethanol solvate of the title molecule and the dimethylformamide solvate of the p-fluoro derivative (Tanaka et al., 2009): two molecules of solvent, ethanol or dimethylformamide, are bonded by hydrogen bonds to both carboxylic acid groups.

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. |

2,5-Diphenyl-1,4-benzenedicarboxylic acid (2,5-Diphenylterephthalic acid) has been described previously as a precursor towards trans-fluorenacenedione, prepared by its dehydration with sulfuric acid (Ebel & Deuschel, 1956).
The compound has a central terephtalic acid core, substituted at positions 2 and 5 with phenyl groups. The molecule has been previoulsy described by Tanaka et al. (Tanaka et al., 2009) in the form of an ethanol solvate. Tanaka et al. also described a related compound where the phenyl groups were replaced by p-fluorophenyl groups, which crystallized as a dimethylformamide solvate.
The carboxylic acid and the phenyl groups are highly planar. They define dihedral angles of 53.18 (11)° and 47.83 (11)°, respectively, with the central aromatic ring. The corresponding values are 28.2 (2)° and 57.2 (1)°, and 115.3 (1)° and 46.3 (1)°, for both dihedral angles in the ethanol solvate, and in the p-fluoro compound, respectively.
The molecule has an inversion center (crystallographic) coincident with the centroid of the central ring, so the point group symmetry of the isolated molecule is Ci. The same happens for the ethanol solvate and the p-fluoro compounds respectively.
The packing shows a deuterated dimethyl sulfoxide solvent molecule hydrogen bonded with each carboxylic acid group, with O1···O3ii distance of 2.581 (2) Å (ii: x + 1, y, z). There are two molecules of solvent for a single diacid molecule, each one defining one of the aforementioned hydrogen bond with each carboxylic acid group. A closely related pattern occurs for the ethanol solvate of the title molecule and the dimethylformamide solvate of the p-fluoro derivative (Tanaka et al., 2009): two molecules of solvent, ethanol or dimethylformamide, are bonded by hydrogen bonds to both carboxylic acid groups.
