Biphenyl-3,3',4,4'-tetra-carboxylic acid dihydrate.

ABSTRACT: 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 bifurcated O-H?(O,O) hydrogen bonds link the mol-ecules to form a three-dimensional supra-molecular network.

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)°.

Crystal structure and Hirshfeld surface analysis of 4,4'-di-meth-oxy-biphenyl-3,3',5,5'-tetra-carb-oxy-lic acid dihydrate.

Project description:In the crystal of the title compound, C18H14O10·2H2O, the arene rings of the biphenyl moiety are tilted at an angle of 24.3 (1)°, while the planes passing through the carboxyl groups are rotated at angles of 8.6 (1) and 7.7 (1)° out of the plane of the benzene ring to which they are attached. The crystal structure is essentially stabilized by O-H⋯O bonds. Here, the carboxyl groups of neighbouring host mol-ecules are connected by cyclic R 2 2(8) synthons, leading to the formation of a three-dimensional network. The water mol-ecules in turn form helical supra-molecular strands running in the direction of the crystallographic c-axis (chain-like water clusters). The second H atom of each water mol-ecule provides a link to a meth-oxy O atom of the host mol-ecule. A Hirshfeld surface analysis was performed to qu-antify the contributions of the different inter-molecular inter-actions, indicating that the most important contributions to the crystal packing are from H⋯O/O⋯H (37.0%), H⋯H (26.3%), H⋯C/C⋯H (18.5%) and C⋯O/O⋯C (9.5%) inter-actions.

3,3'-[Biphenyl-4,4'-diylbis(-oxy)]diphthalic acid.

Project description:In the title mol-ecule, C(28)H(18)O(10), the two central benzene rings form a dihedral angle of 31.0?(1)°. In the phthalic acid fragments, the carb-oxy groups in the meta positions are approximately coplanar with the attached benzene rings, being inclined to their planes at 2.7?(1) and 10.3?(1)°, while the carb-oxy groups in the ortho positions are twisted from the benzene ring planes by 83.5?(1) and 75.4?(1)°. In the crystal, O-H?O hydrogen bonds link the mol-ecules into layers parallel to the bc plane. Weak C-H?O hydrogen bonds and ?-? inter-actions between the aromatic rings [centroid-centroid distance = 3.7674?(3)?Å] further consolidate the crystal packing.

Poly[[tetra-aqua-(μ(6)-2,2'-diiodo-biphenyl-4,4',5,5'-tetra-carboxyl-ato)dizinc(II)] dihydrate].

Project description:In the title compound, {[Zn(2)(C(16)H(4)I(2)O(8))(H(2)O)(4)]·2H(2)O}(n), two crystallographically independent Zn(II) atoms are each located on a twofold rotation axis. Both Zn(II) atoms are in distorted octa-hedral coordination geometries: one is coordinated by six O atoms from four carboxyl-ate groups, while the other is coordinated by two carboxyl-ate groups and four water mol-ecules. The tetra-carboxyl-ate ligand mol-ecules connect the Zn(II) atoms, completing a three-dimensional metal-organic framework. O-H⋯O hydrogen bonds link the metal-organic framework with the uncoord-inated water mol-ecules.

4,4'-Bipyridine-butane-1,2,3,4-tetra-carboxylic acid (1/1).

Project description:The title compound, C(10)H(8)N(2)·C(8)H(10)O(8), is an example of a system with a short O⋯H⋯N hydrogen bond [O⋯N = 2.565 (3) Å]. The crystal structure comprises a 1:1 adduct between 4,4'-bipyridine and butane-1,2,3,4-tetra-carboxylic acid, where both components are centrosymmetric. The component mol-ecules are linked through strong O⋯H⋯N hydrogen bonds, forming chains extending approximately along [11]. The chains are inter-connected by O⋯H⋯O hydrogen bonds and weak stacking inter-actions involving the pyridyl rings of the 4,4'-bipyridine mol-ecules [centroid-centroid distance = 3.73 (2) Å and inter-planar distance = 3.35 (1) Å]. The H atom of the short O⋯H⋯N hydrogen bond is disordered over two positions with site occupancy factors of ca 0.6 and 0.4. One methylene group is disordered over two positions; the site occupancy factors are ca 0.9 and 0.1.

Di-μ-chlorido-bis-[dichlorido(3,3',5,5'-tetra-methyl-4,4'-bipyrazol-1-ium-κN)copper(II)] dihydrate.

Project description:The structure of the centrosymmetric title compound, [Cu(2)Cl(6)(C(10)H(15)N(4))(2)]·2H(2)O, consists of a dimeric [{(HMe(4)bpz)CuCl(3)}(2)] unit (HMe(4)bpz is 3,3',5,5'-tetra-methyl-4,4'-bipyrazol-1-ium) with two solvent water molecules. Each [HMe(4)bpz](+) cation is bonded to a CuCl(3) unit through a Cu-N dative bond, effectively making square-planar geometry at the Cu atom. Two of these units then undergo a face-to-face dimerization so that the Cu atoms have a Jahn-Teller distorted square-pyramidal geometry with three chlorides and an N atom in the basal plane and one chloride weakly bound in the apical position. Several N-H⋯Cl, O-H⋯Cl and N-H⋯O hydrogen bonds form a three-dimensional network.
