Diammonium diaqua-bis(malonato-?O,O')cobaltate(II) dihydrate.

ABSTRACT: The title complex, (NH(4))(2)[Co(C(3)H(3)O(4))(2)(H(2)O)(2)]·2H(2)O, features a six-coordinate Co atom located on a center of symmetry. The octa-hedral O(6) coordination geometry is defined by two bidentate malonate ligands and two water mol-ecules, with the latter in a trans configuration. The mol-ecules are linked through O-H?O and N-H?O hydrogen-bonding inter-actions, forming a three-dimensional supra-molecular network.

The title complex, (NH(4))(2)[Co(C(3)H(3)O(4))(2)(H(2)O)(2)]·2H(2)O, features a six-coordinate Co atom located on a center of symmetry. The octa-hedral O(6) coordination geometry is defined by two bidentate malonate ligands and two water mol-ecules, with the latter in a trans configuration.

Project description:In the title cobalt(II) complex with 2-methyl-anilinium and diphosphate, (C(7)H(10)N)(2)[Co(H(2)P(2)O(7))(2)(H(2)O)(2)], a three-dimensional network is built up from anionic layers of [Co(H(2)P(2)O(7))(2)(H(2)O)(2)](2-) units and 2-methyl-anilinium cations located between these layers. The dihydrogendiphosphate groups present a bent eclipsed conformation, while the Co(2+) ions lie on inversion centers. An intricate network of O-H?O and N-H?O hydrogen bonds is established between the different components, assuring the cohesion of the network with other inter-actions, being of electrostatic and van der Waals nature.

Diacridinium trans-diaqua-bis(pyrazine-2,3-dicarboxyl-ato)cobaltate(II) hexa-hydrate.

Project description:The title compound, (C(13)H(10)N)(2)[Co(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O, consists of mononuclear trans-[Co(pz-2,3-dc)(2)(H(2)O)(2)](2-) complex anions, (acrH)(+) cations and uncoordinated water mol-ecules (acr is acridine and pz-2,3-dcH(2) is pyrazine-2,3-dicarboxylic acid). The Co(II) atom, which lies on a crystallographic center of symmetry, has a slightly distorted octa-hedral coordination environment, with two N and two O atoms from the (pz-2,3-dc)(2-) ligands in the equatorial plane and with two water mol-ecules in axial positions. In the crystal, the components are held together by two distinct N-H?O and C-H?O hydrogen bonds with R(2) (2)(8) graph-sets. The coordinated and uncoordinated water mol-ecules are also involved in O-H?O hydrogen bonds, which lead to the formation of layers with R(3) (3)(12) graph-set motifs. Extensive ?-? stacking inter-actions between parallel aromatic rings of the acridinium ions, with distances ranging from 3.533?(1) to 3.613?(1)?Å, occur in the structure.

Diaqua-bis-(4-meth-oxy-benzoato-?O)bis-(nicotinamide-?N)nickel(II) dihydrate.

Project description:In the mononuclear title compound, [Ni(C(8)H(7)O(3))(2)(C(6)H(6)N(2)O)(2)(H(2)O)(2)]·2H(2)O, the Ni(II) ion is located on a crystallographic inversion center.

The four O atoms in the equatorial plane around the Ni(II) ion form a slightly distorted square-planar arrangement, while the slightly distorted octa-hedral coordination is completed by the two pyridine N atoms of the NA ligands in the axial positions. The dihedral angle between the carboxyl-ate group and the attached benzene ring is 7.2?(1)°, while the pyridine and benzene rings are oriented at a dihedral angle of 72.80?(4)°. An intra-molecular O-H?O hydrogen bond links the uncoordinated water mol-ecule to one of the carboxyl-ate groups. In the crystal structure, inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds link the mol-ecules into a three-dimensional network.
