چکیده
In the title compound, C(18)H(12)O(5), the anthracene moiety is almost planar (r.m.s. deviation = 0.0399 Å). In the crystal, mol-ecules are linked to each other by inter-molecular O-H⋯O and weak C-H⋯O hydrogen bonds.

The title complex, {[Co2(C18H4O10)(C14H14N4)2]·2H2O} n was synthesized from CoCl2·6H2O, 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carb-oxy-lic acid (H4AQTC) and 1,2-bis-[(1H-imidazol-1-yl)meth-yl]benzene (o-bix) in water. The anthraquinone unit is located about a crystallographic center of inversion. Each asymmetric unit therefore contains one Co(II) atom and one o-bix ligand, as well as...

In the crystal of the title polymeric complex, [Ni(2)(C(18)H(4)O(10))(C(10)H(8)N(2))(H(2)O)(8)](n), each Ni(II) cation is coord-in-ated by four water mol-ecules in the equatorial plane, and is further bridged by an 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carb-oxy-l-ate anion and a 4,4'-bipyridine ligand in the axial directions, forming a distorted octa-hedral geometry. The 9,10-dioxo-9...
