Crystal structure of tetraaquabis(8-chloro-9,10-dioxo-9,10-dihydroanthracene-1-carboxyl-ato-?O (1))cobalt(II) dihydrate.

ABSTRACT: 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 ?-? 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.

Project description:The title complex, [Mn(2)(C(18)H(4)O(10))(H(2)O)(4)](n), was synthesized from manganese(II) chloride tetra-hydrate and 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carb-oxy-lic acid (H(4)AQTC) in water. The anthraquinone unit is located about a crystallographic center of inversion. Each asymmetric unit therefore contains one Mn(II) atom, two water ligands and one half AQTC(4-) anion. The Mn(II) atom is coordinated in a distorted octa-hedral geometry by four O atoms from three AQTC(4-) ligands and two water O atoms. Two of the carboxyl-ate groups coordinate one Mn(II) atom in a chelating mode, whereas the others each coordinate two Mn(II) atoms. Each AQTC(4-) tetra-anion therefore coordinates six different Mn(II) ions and, as a result, a three-dimensional coordination polymer is formed. O-H?O hydrogen bonds, some of them bifurcated, between water ligands and neighboring water or anthraquinone ligands are observed in the crystal structure.

Project description:In the title complex, [Co(C(6)H(5)N(2)O(2))(2)(H(2)O)(2)]·2H(2)O, the coordination geometry of the Co(2+) cation is distorted octa-hedral, with two N atoms and two O atoms from two 5-methyl-pyrazine-2-carboxyl-ate ligands in the equatorial plane. The two remaining coordination sites are occupied by two water mol-ecules. In addition, there are two uncoordinated water mol-ecules in the asymmetric unit. The crystal structure is stabilized by a network of O-H?O and O-H?N hydrogen-bonding inter-actions, forming a three-dimensional structure.

Project description: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.

Project description: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-9,10-dihydro-anthracene-1,4,5,8-tetra-carboxyl-ate anion is centrosymmetric with the centroid of the quinone ring located about an inversion center; the 4,4'-bipyridine ligand is also centrosymmetric with the mid-point of the C-C bond linking two pyridine rings located about another invertion center. The 9,10-dioxo-9,10-dihydro-anthracene-1,4,5,8-tetra-carboxyl-ate anion and bypiridine ligand bridge the Ni(II) cations, forming a polymeric chain along the b axis. ?-? stacking is observed between pyridine and benzene rings [centroid-centroid distance = 3.705?(2)?Å]. All of the coordinating water mol-ecules are involved in O-H?O hydrogen bonding.
