Biphenyl-3,3′,4,4′-tetracarboxylic acid dihydrate

چکیده
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.

Multivalent benzene polyphosphate derivatives are non-Ca2+-mobilizing Ins(1,4,5)P3 receptor antagonists.
Inositol 1,4,5-trisphosphate [Ins(1,4,5)P31] mobilizes intracellular Ca2+ through the Ins(1,4,5)P3 receptor [InsP3R]. Although some progress has been made in the design of synthetic InsP3R partial agonists and antagonists, there are still few examples of useful small molecule competitive antagonists. A "multivalent" approach is explored and new dimeric polyphosphorylated aromatic derivatives we...
متن کاملMolecular Dynamics and Molecular Docking Studies on the Interaction between Four Tetrahydroxy Derivatives of Polyphenyls and Beta Amyloid
Interactions of 3,3',4,4'-tetrahydroxybiphenyl (BPT) and three isomeric 3,3",4,4"-tetrahydroxyterphenyls (OTT, MTT, PTT) with Alzheimer’s amyloid-β peptide (Aβ) were studied by molecular dynamics simulation and molecular docking. Structural parameters such as Root-mean-square derivations (RMSD), radial distribution function (RDF), helix percentage and other physical parameters were obtained. Th...
متن کاملThe three-dimensional structure of 3,3',4,4'-tetrachlorobiphenyl, a dioxin-like polychlorinated biphenyl (PCB).
The crystal structure of PCB 77 (3,3',4,4'-tetrachlorobiphenyl, C(12)H(6)Cl(4)), a dioxin-like PCB congener, is described. The dihedral angle of PCB 77 is 43.94(6) degrees, which is slightly larger than calculated or experimental dihedral angles of biphenyl derivatives in solution but smaller than experimental dihedral angles in the gas phase.

The asymmetric unit of the title complex, [Ni(2)(C(16)H(6)O(8))(C(10)H(8)N(2))(2)(H(2)O)(6)]·6H(2)O, contains one Ni(II) atom, one 2,2'-bipyridine ligand, three coordinated water mol-ecules, one-half of a fully deprotonated biphenyl-3,3',4,4'-tetra-carboxyl-ate anion and three lattice water mol-ecules. The Ni(II) atom displays a distorted NiN(2)O(4) octa-hedral coordination formed by one carbox...
