چکیده
The title compound, C(12)H(14)N(4), has a crystallographically imposed centre of symmetry. Inter-molecular N-H⋯N hydrogen bonds between amino groups link adjacent mol-ecules into a three-dimensional network where ten-membered hydrogen-bonded rings are observed.

Molecular 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...
