Bis(2-amino-4-methyl-pyridinium) trans-diaqua-bis-(pyrazine-2,3-dicarboxyl-ato)cuprate(II) hexa-hydrate.

ABSTRACT: The title compound, (C(6)H(9)N(2))(2)[Cu(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O, consists of a mononuclear trans-[Cu(pzdc)(2)(H(2)O)(2)](2-) dianion (pzdc is pyrazine-2,3-dicarboxyl-ate) and two [ampyH](+) cations (ampy is 2-amino-4-methyl-pyridine) with six water mol-ecules of solvation. The Cu(II) atom is hexa-coordinated by two pzdc groups and two water mol-ecules. The coordinated water mol-ecules are in trans-diaxial positions and the pzdc dianion acts as a bidentate ligand through an O atom of the carboxyl-ate group and the N atom of the pyrazine ring. There are diverse hydrogen-bonding inter-actions, such as N-H?O and O-H?O contacts, which lead to the formation of a three-dimensional supra-molecular architecture.

Bis(2-amino-6-methyl-pyridinium) trans-diaqua-bis-(pyrazine-2,3-dicarboxyl-ato)cuprate(II) hexa-hydrate.

Project description:The title compound, (C(6)H(9)N(2))(2)[Cu(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O, was obtained by the reaction of CuCl(2)·2H(2)O with pyrazine-2,3-dicarb-oxy-lic acid (pyzdcH(2)) and 2-amino-6-methyl-pyridine (2a-6mpy) in aqueous solution. The Cu(II) atom is located on an inversion centre and has an overall octa-hedral coordination environment. Two N and two O atoms from (pyzdc)(2-) ligands define the equatorial plane and two water mol-ecules are in axial positions, resulting in a typical tetra-gonally Jahn-Teller-distorted environment. Extensive classical O-H?O, O-H?N and N-H?O and non-classical C-H?O hydrogen bonds, as well as ?-? stacking inter-actions between aromatic rings of the cations [centroid-centroid distance = 3.58?(9)?Å], lead to the formation of a three-dimensional supra-molecular structure.

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.

The Cu(II) atom has a tetra-gonally distorted octa-hedral coordination environment. The structure features extensive hydrogen bonding, with 21 distinct inter-actions. There is also a centrosymmetric C=O?? inter-action with an O?centroid distance of 3.288?(3)?Å. The structure is similar to a mixed-valence manganese(II/III) structure but shows inter-esting differences in the metal-atom coordination. One of the water molecules is equally disordered with respect to a twofold axis.
