The crystal structures in two solid phases, i.e. phase II stable between 146 and 253 K and phase IV below 136 K, of the title compound [phenazine-chloranilic acid (1/1), C12H8N2.C6H2Cl2O4, in phase II, and phenazinium hydrogen chloranilate, C12H9N2+.C6HCl2O4-, in phase IV], have been determined. Both phases crystallize in P2(1), and each structure was refined as an inversion twin. In phase II, ...

Phenazines, including pyocyanin and iodonin, are biologically active compounds that are believed to confer producing organisms with a competitive growth advantage, and also are thought to be virulence factors in certain diseases including cystic fibrosis. The basic, tricyclic phenazine ring system is synthesized in a series of poorly characterized steps by enzymes encoded in a seven-gene cistro...

In the mol-ecule of the title compound, C(11)H(12)O(2), the cyclo-hexane ring adopts a half-chair conformation. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by pairs of O-H⋯O hydrogen bonds, and the dimers are linked together by π-π inter-actions [centroid-centroid distance = 3.8310 (13) Å] and C-H⋯O bonds.

Abstract It is generally accepted that some trace organic contaminants (TrOCs) pass through the wastewater treatment process without being properly treated and find their way into waterbodies. These molecules can also be concentrated within biosolids (BS) adsorption. The presence of TrOCs in BS, which are then commonly used as soil amendments agriculture, may affect plant growth viability. pote...
