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

ABSTRACT: 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.

trans-Di-aqua-bis-(pyridazine-3-carboxyl-ato-κ(2) N (2),O)cobalt(II) dihydrate.

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 equatorial plane is formed by two trans-related N,O-bidentate pyridazine-3-carboxyl-ate ligands and the axial positions are occupied by two water mol-ecules. 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.

Bis(μ-pyridazine-3-carboxyl-ato-κO:O')bis-[aqua-dioxido(pyridazine-3-carboxyl-ato-κN,O)uranium(VI)] dihydrate.

Project description:The structure of the binuclear title complex, [U(2)(C(5)H(3)N(2)O(2))(4)O(4)(H(2)O)(2)]·2H(2)O, is composed of centrosymmetric dimers in which each UO(2) (2+) ion is coordinated by two ligand mol-ecules. One donates its N,O-bonding group and the other donates both carboxyl-ate O atoms. Each of the latter bridges adjacent uranyl ions. The coordination environment of the metal center is a distorted penta-gonal bipyramid. The dimers are inter-connected by O-H⋯O hydrogen bonds between coordinated and uncoordinated water mol-ecules and carboxyl-ate O atoms. An intra-molecular O-H⋯N inter-action is also present.

Project description:In the title compound, [Cu(C5H3N2O2)2(H2O)2], the Cu(II) ion, located on an inversion center, exhibits an octa-hedral coordination geometry. The equatorial plane is defined by two trans-related N,O-bidentate pyridazine-3-carboxyl-ate ligands and the axial positions are occupied by two water mol-ecules. In the crystal, mol-ecules are connected by O-H⋯O hydrogen bonds between the water mol-ecules and the noncoordinating carboxyl-ate O atoms, forming layers parallel to the bc plane. The layers are stacked along the a axis by further O-H⋯O hydrogen bonds between the water mol-ecules and the coordinating carboxyl-ate O atoms. Weak C-H⋯O hydrogen bonds are also observed between the pyridazine rings and the water mol-ecules and between the pyridazine rings and the non-coordinating carboxyl-ate O atoms.

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.
