Trans-Diaqua-(pyridazine-3-carboxyl-ato-κN,O)lithium.

ABSTRACT: The structure of the title complex, [Li(C(5)H(3)N(2)O(2))(H(2)O)(2)], is built of monomeric mol-ecules. In each, an Li(+) ion is N,O-chelated by the pyridazine-3-carboxyl-ate ligand and two water O atoms. The coordination geometry of the metal ion is distorted tetra-hedral. The monomers are linked by a system of hydrogen bonds in which water mol-ecules act as donors and carboxyl-ate O atoms act as acceptors. O-H⋯N hydrogen bonding is also present.

Project description:In the title centrosymmetric complex, [Zn(C(7)H(5)N(2)O(4))(2)(H(2)O)(2)]·2H(2)O, the Zn(II) ion is coordinated in a trans mode by two symmetry-related bis-chelating 6-methoxycarbonyl-pyridazine-3-carboxyl-ate ligands via N and O atoms, and by two aqua ligand O atoms in axial positions, in a slightly distorted octa-hedral environment. In the crystal structure, complex mol-ecules are linked by inter-molecular O-H⋯O hydrogen bonds between coordinated and solvent water mol-ecules and carboxyl-ate O atoms, forming mol-ecular ribbons propagating along the a axis.

Project description:In the title complex, [Ni(C(4)H(3)N(2)O(2))(2)(H(2)O)(2)], the Ni(II) ion is located on an inversion center and shows a distorted octa-hedral geometry, defined by two N,O-bidentate 1H-imidazole-4-carboxyl-ate ligands in the equatorial plane and two water mol-ecules in the axial positions. Inter-molecular N-H⋯O hydrogen bonds link the complex mol-ecules into layers parallel to (10[Formula: see text]), which are further linked into a three-dimensional supra-molecular network through O-H⋯O hydrogen bonds.

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.

Bis[[(6-carb-oxy-pyridazine-3-carboxyl-ato-κN,O)lithium]-μ-penta-hydrogen-dioxy-gen(1+)].

Project description:The structure of the title compound, [Li(C(6)H(3)N(2)O(4))(2)(H(5)O(2))], is composed of centrosymmetric monomers in which an Li(I) ion is chelated by two N,O-bonding groups donated by two ligands. The Li(I) ion and both ligand mol-ecules are coplanar [r.m.s. deviation 0.0047 (2) Å] and water O atoms are in the axial positions. The second carboxyl group of each ligand remains protonated. An additional H atom, located between adjacent coordinated water mol-ecules and observed on Fourier maps, maintains the charge balance within the monomers and bridges them by short symmetric hydrogen bonds of 2.518 (3) Å to form catenated ribbons. The monomers also inter-act via hydrogen bonds in which water and carboxyl O atoms act as donors.

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.

Poly[aqua-(μ(3)-pyridazine-4-carboxyl-ato-κO:O:O')lithium].

Project description:The structure of the title compound, [Li(C(5)H(3)N(2)O(2))(H(2)O)](n), is composed of centrosymmetric dimers in which two Li(I) ions are bridged by a carboxyl-ate O atom, each donated by a ligand, acting in a bidentate mode. The second carboxyl-ato O atoms bridge the dimers to Li(I) ions in adjacent dimers, forming mol-ecular layers parallel to (001). Each Li(I) ion is coordinated by two bridging carboxyl-ate O atoms, a bridging carboxyl-ate O atom donated by the adjacent dimer and an aqua O atom, resulting in a distorted tetra-hedral coordination geometry. The layers are held together by O-H⋯N hydrogen bonds in which coordinated water O atoms act as donors and ligand hetero-ring N atoms as acceptors.
