| Popis: | The title complex, {[Co2(C18H4O10)(C14H14N4)2]·2H2O}n was synthesized from CoCl2·6H2O, 9,10-dioxo-9,10-dihydroanthracene-1,4,5,8-tetracarboxylic acid (H4AQTC) and 1,2-bis[(1H-imidazol-1-yl)methyl]benzene (o-bix) in water. The anthraquinone unit is located about a crystallographic center of inversion. Each asymmetric unit therefore contains one CoII atom and one o-bix ligand, as well as half an AQTC4− ligand and an additional solvent water molecule. The CoII ions are tetrahedrally surrounded by two O atoms from two AQTC4− anions and by two N atoms from two o-bix ligands, forming a two-dimensional coordination polymer. The solvent water molecules are connected to the carboxylate groups by O—H...O hydrogen bonds. Additional weak C—H...O hydrogen bonds are observed in the crystal structure. |
