Bis(3-amino-pyrazine-2-carboxyl-ato-?(2) N (1),O)di-aqua-nickel(II) dihydrate.

ABSTRACT: In the title compound, [Ni(C5H4N3O2)2(H2O)2]·2H2O, the Ni(II) ion lies on an inversion center and is coordinated in an slightly distorted octa-hedral environment by two N,O-chelating 3-amino-pyrazine-2-carboxyl-ate (APZC) ligands in the equatorial plane and two trans-axial aqua ligands. In the crystal, O-H?O, N-H?O and O-H?N hydrogen bonds involving the solvent water mol-ecules, aqua and APZC ligands form layers parallel to (010). These layers are linked further via O-H?O, N-H?O and C-H?O hydrogen bonds involving the axial aqua ligands, amino groups and the carboxyl-ate groups of the APZC ligands, forming a three-dimensional network.

Project description:The asymmetric unit of the title compound, {(C(5)H(7)N(2))(2)[Ni(C(10)H(2)O(8))(H(2)O)(4)]·2H(2)O}(n), contains an Ni(II) atom, two water mol-ecules of coordination, one half of a benzene-1,2,4,5-tetra-carboxyl-ate (btec) anionic ligand, one 4-amino-pyridinium cation (papy) and an uncoordinated water mol-ecule. The metal center lies on an inversion center and adopts an octa-hedral geometry with the carboxyl-ate groups tilted out of the mean plane formed by the btec. In the crystal, mol-ecules are linked into one-dimensional coordination polymers running along the ac diagonal. The crystal structure is consolidated by N-H⋯O and O-H⋯O hydrogen bonds.

Crystal structure of tetra-aqua-bis(3,5-di-amino-4H-1,2,4-triazol-1-ium)cobalt(II) bis-[bis-(pyridine-2,6-di-carboxyl-ato)cobaltate(II)] dihydrate.

Project description:The asymmetric unit of the title compound, [Co(C2H6N5)2(H2O)4][Co(C7H3NO4)2]2·2H2O, features 1.5 Co(II) ions (one anionic complex and one half cationic complex) and one water mol-ecule. In the cationic complex, the Co(II) atom is located on an inversion centre and is coordinated by two triazolium cations and four water mol-ecules, adopting an octa-hedral geometry where the N atoms of the two triazolium cations occupy the axial positions and the O atoms of the four water mol-ecules the equatorial positions. The two triazole ligands are parallel offset (with a distance of 1.38 Å between their planes). In the anionic complex, the Co(II) ion is six-coordinated by two N and four O atoms of the two pyridine-2,6-di-carboxyl-ate anions, exhibiting a slightly distorted octa-hedral coordination geometry in which the mean plane of the two pyridine-2,6-di-carboxyl-ate anions are almost perpendicular to each other, making a dihedral angle of 85.87 (2)°. In the crystal, mol-ecules are linked into a three-dimensional network via C-H⋯O, C-H⋯N, O-H⋯O and N-H⋯O hydrogen bonds.

Project description:In the polymeric complex of the title compound, {[AgNi(C(5)H(3)N(2)O(2))(2)(H(2)O)(2)]NO(3)·2H(2)O}(n), the Ag(I) ion displays an angular coordination geometry with two N atoms from pyrazine-2-carboxyl-ate ligands, and the Ni(II) ion is hexa-coordinated by two O atoms from two water mol-ecules, two O and two N atoms from pyrazine-2-carboxyl-ate ligands in a distorted octa-hedral geometry.

Di-μ-aqua-bis-(μ-pyridazine-4-carboxyl-ato-κN:N')bis-[triaqua-(pyridazine-4-carboxyl-ato-κO,O')lead(II)] dihydrate.

Project description:The structure of the title compound, [Pb(2)(C(5)H(3)N(2)O(2))(4)(H(2)O)(6)]·2H(2)O, is composed of dimeric mol-ecules in which two symmetry-related Pb(2+) ions are bridged by a pair of two pyridazine-4-carboxyl-ate ligand mol-ecules via both heterocyclic N atoms and two water O atoms. Each Pb(2+) ion is also coordinated by two carboxyl-ate O atoms and three water O atoms, leading to a highly irregular coordination polyhedron around Pb(2+). The dimers are inter-connected by hydrogen bonds between coordinated and uncoordinated water mol-ecules and the carboxyl-ate O atoms. O-H⋯N inter-actions are also present.

Project description:The title compound, [Co(C5H3N2O2)2(H2O)2]·2H2O, contains a Co(II) ion on an inversion center, exhibiting an octa-hedral coordination geometry.

The Co(II) complex mol-ecules are stacked in a column along the a-axis direction by an O-H⋯N hydrogen bond between the non-coordinating pyridazine N atom and the coordinating water mol-ecule. These columns are further connected into a layer parallel to the ac plane by additional hydrogen bonds involving the coordinating and non-coordinating water mol-ecules, and the non-coordinating carboxyl-ate O atom. The crystal packing is completed by inter-layer weak C-H⋯O inter-actions.
