Biphenyl-3,3′,4,4′-tetracarboxylic acid dihydrate
The asymmetric unit of the title compound, C(16)H(10)O(8)·2H(2)O, contains one-half of the centrosymmetric organic mol-ecule and one water mol-ecule. The dihedral angles between the carboxyl-ate groups and the adjacent phenyl ring are 71.31 (3) and 16.67 (3)°, while the carboxyl-ate groups are oriented at a dihedral angle of 72.01 (3)°. In the crystal structure, inter-molecular O-H⋯O and bifurc...

The asymmetric unit of the title compound, C(14)H(10)O(4), contains one half mol-ecule, the complete mol-ecule being generated by a twofold axis. The two benzene rings form a dihedral angle of 43.11 (5)°. Inter-molecular O-H⋯O hydrogen bonds link the mol-ecules into one-dimensional zigzag chains. These chains are further connected into two-dimensional supra-molecular layers by weak π-π stacking...

In the crystal structure of the title compound, C(16)H(10)N(2)O(8)·2H(2)O, the organic mol-ecule is located on a centre of symmetry. The two benzene rings are parallel, but not coplanar, as indicated by N=N-C-C torsion angles involving the azo group of 12.1 (5) and -168.2 (3)°. The organic mol-ecule and the water mol-ecule are linked by O-H⋯O hydrogen bonds, forming a three-dimensional network.

The asymmetric unit of the title compound, C(8)H(4)Br(2)O(4)·2H(2)O, contains one half-mol-ecule of 2,5-dibromo-terephthalic acid (DBTA) and one water mol-ecule. The DBTA mol-ecule is centrosymmetric. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules, forming a three-dimensional framework.
متن کامل2,5-Dihydroxyterephthalic acid dihydrate
The title compound, C(8)H(6)O(6)·2H(2)O, was obtained by accident within a project on the synthesis of metal-organic coordination polymers by the reaction of LiOH with 2,5-dihy-droxy-terephthalic acid under solvothermal conditions. The asymmetric unit consists of half a 2,5-dihy-droxy-terephthalic acid mol-ecule located on a centre of inversion and one solvent water mol-ecule that occupies a ge...
