Project description:The asymmetric unit of the polymeric title compound, {[Pr(2)(C(5)H(4)N(3)O(2))(5)(CHO(2))(H(2)O)(5)]·6H(2)O}(n), has two independent Pr(III) atoms; one is coordinated by two water mol-ecules and the other by three water mol-ecules. The first is N,O-chelated by three 3-amino-pyrazine-2-carboxyl-ate ions, whereas the second is chelated by two carboxyl-ate ions; both exist in a monocapped square-anti-prismatic geometry. The polymeric chains that run along the a axis inter-act with the lattice water mol-ecules, generating a three-dimensional hydrogen-bonded network. The formate ion is disordered over two positions with respect to the non-coordinated atoms in a 1:1 ratio.

Bis(2-amino-4-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, 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)cobaltate(II) octa-hydrate.

Project description:The title compound, (C(6)H(9)N(2))(2)[Co(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·8H(2)O, was obtained by the reaction of CoCl(2)·6H(2)O with 1,4-pyrazine-2,3-dicarb-oxy-lic acid and 2-amino-6-methyl-pyridine in aqueous solution (molar ratio 1:2:2). The Co(II) ion is situated on an inversion centre and is coordinated by two O and two N atoms of two symmetry-related 1,4-pyrazine-2,3-dicarboxyl-ate ligands and two water mol-ecules and has a disorted octa-hedral coordination environment. The asymmetric unit also contains four water mol-ecules. In the crystal, extensive inter-molecular classical N-H?O, O-H?O and O-H?N hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 3.490?(1)?Å] connect the various components, forming a three-dimensional network.

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.

Project description:In the title complex, [Mn(C(8)H(9)N(2)O(4))(2)(H(2)O)(2)]·3.5H(2)O, the Mn(II) cation is six-coordinated by two N,O-bidentate H(2)pimda(-) ligands (H(2)pimda(-) = 5-carb-oxy-2-propyl-1H-imidazole-4-carboxyl-ate) and two water mol-ecules in a distorted octa-hedral environment. The complete solid-state structure can be described as a three-dimensional supra-molecular framework stabilized by a wide range of O-H⋯O and N-H⋯O hydrogen bonds. The propyl groups of H(2)pimda(-) are disordered over two sets of sites with refined occupancies of 0.759 (5):0.241 (5) and 0.545 (7):0.455 (7).

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.
