چکیده
In the title complex, [Co(C15H6ClO4)2(H2O)4]·2H2O, the Co(II) ion is bound by two carboxylate O atoms of two 5-chloro-9,10-anthra-quinone-1-carboxyl-ate anions and four water O atoms in a trans conformation, forming an irregular octa-hedral coordination geometry. This arrangement is stabilized by intra-molecular O-H⋯O hydrogen bonds between water and carboxyl-ate. Further O-H⋯O hydrogen bonds between coordinating and non-coordinating water and carboxyl-ate produce layers of mol-ecules that extend parallel to (001). The organic ligands project above and below the plane. Those ligands of adjacent planes are inter-digitated and there are π-π inter-actions between them with centroid-centroid distances of 3.552 (2) and 3.767 (2) Å that generate a three-dimensional supra-molecular structure.

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...

متن کاملInteraction of new, very potent non-nucleotide antagonists with Arg256 of the human platelet P2Y12 receptor.
The P2Y(12) receptor plays a crucial role in platelet aggregation. In the present study, we analyzed the properties of non-nucleotide antagonists at the recombinant human P2Y(12) receptor and searched for amino acids involved in the molecular interaction. Receptor function was assessed by measuring the cAMP response element (CRE)-directed luciferase expression in Chinese hamster ovary cells. Th...

The title complex, {[Mn(C(14)H(6)O(8)S(2))(C(12)H(8)N(2))(2)]·4H(2)O}(n), exhibits a chain-like polymeric structure with 9,10-dioxo-anthracene-1,5-disulfonate anions bridging Mn(II) atoms in a bis-monodentate mode. The unique Mn(II) atom is located on a crystallographic centre of inversion. Four N atoms from two chelating 1,10-phenanthroline ligands and two sulfonate O atoms from two symmetry-r...
