ABSTRACT: In the title heterotrinuclear coordination compound, [CaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(3)]·7H(2)O, the Ca(2+) cation is in a penta-gonal-bipyramidal geometry and bridges two (1H-imidazole)[2-(oxaloamino)benzoato(3-)]copper(II) units in its equatorial plane. Each Cu(II) atom has a normal square-planar geometry. The mol-ecule has approximate local (non-crystallographic) mirror symmetry and 23 classical hydrogen bonds are found in the crystal structure.

Project description:In the title coordination polymer, {[BaCu(2)(C(9)H(4)NO(5))(2)(C(3)H(4)N(2))(2)(H(2)O)(4)]·2H(2)O}(n), the Ba(2+) cation is deca-coordinate, ligated by four aqua ligands and four [Cu(C(9)H(4)O(5)N)(C(3)H(4)N(2))] 'complex ligands'. The Cu(II)-containing complex-ligands are bridged by the Ba(2+) cations, resulting in a one-dimensional polymeric chain structure. The crystal structure is maintained via N-H⋯O and O-H⋯O hydrogen bonds. There is one disordered solvent water mol-ecule in the asymmetric unit, with occupancies of 0.44 (2) and 0.56 (2).

Bis(μ-4-hydroxy-benzoato-κO:O')bis-[triaqua-bis(4-hydroxy-benzoato)-κO;κO,O'-terbium(III)] deca-hydrate.

Project description:The title dinuclear compound, [Tb(2)(C(7)H(5)O(3))(6)(H(2)O)(6)]·10H(2)O, lies on a center of inversion and the two Tb(III) atoms are bridged by two 4-hydroxy-benzoate anions; each metal atom is further coordinated by one monodentate anion and chelated by the third anion. The eight-coordinate geometry approximates a square anti-prism. Hydrogen bonds of the O-H⋯O type connect the uncoordinated water mol-ecules to the dinuclear species, forming a three-dimensional network.

Project description:The dinuclear title compound, [Co(2)(C(10)H(8)N(4)O(4))(2)(H(2)O)(4)]·6H(2)O, lies about an inversion centre. Each Co(II) atom is six-coordinated by two water mol-ecules, two carboxyl-ate O atoms and two N atoms of two symmetry-related 2,2'-bi-1H-imidazole-1,1'-diacetate (L(2-)) ligands in a slightly distorted octa-hedral geometry. Mol-ecules are linked into a three-dimensional framework via O-H⋯O and C-H⋯O hydrogen bonds.

Project description:The title compound, [Ni(2)(C(7)H(5)O(3))(4)(C(7)H(6)N(2))(4)][Ni(C(7)H(5)O(3))(2)(C(7)H(6)N(2))(2)]·6H(2)O, is a mononuclear/dinuclear nickel(II) cocrystal, the two mol-ecular species inter-acting through hydrogen bonds that involve the uncoordinated water mol-ecules. In the mononuclear species, the Ni(II) ion, located on an inversion center, is coordinated by two 1H-benzimidazole (bzim) ligands and two 3-hydroxy-benzoate (hba) anions in a square-planar geometry. In the centrosymmetric dinuclear species, the Ni(II) ion is coordinated by two bzim ligands and three hba anions in a square-pyramidal geometry; of the two independent hba anions, one bridges two Ni(II) ions with both carboxylate and hydroxyl groups whereas the other coordin-ates in a unidentate manner to the Ni(II) ion. The apical Ni-O(hydrox-yl) bond is 0.39 Å longer than the basal Ni-O(carbox-yl) bonds. The face-to-face separation of 3.326 (9) Å indicates the existence of π-π stacking between parallel bzim ligands of adjacent dinuclear entities. Extensive N-H⋯O and O-H⋯O hydrogen bonds help to stabilize the crystal structure.

The naphthalene-dicarboxyl-ate dianion links both Ni(II) complex cations via O-H?O and N-H?O hydrogen bonding, but no ?-? stacking is observed between aromatic rings in the crystal structure. One imidazole ligand is equally disordered over two sites about a twofold rotation axis; one N atom and one water O atom have site symmetry 2.

Aquabis(benzoato-κO)bis-(1H-imidazole-κN)copper(II) monohydrate.

Project description:In the title compound, [Cu(C(7)H(5)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)]·H(2)O, the Cu(II) atom is in a distorted square-pyramidal environment. The mol-ecules are assembled into double chains extending along [010] by N-H⋯O hydrogen bonds. These double chains are linked by O-H⋯O hydrogen bonds, forming layers parallel to (02); the layers are linked into a three-dimensional network by van der Waals inter-actions.

catena-Poly[[[diaqua-cadmium(II)]-bis-[μ-3,5-bis-(isonicotinamido)benzoato]] tetra-hydrate].

Project description:The title compound, {[Cd(C(19)H(13)N(4)O(4))(2)(H(2)O)(2)]·4H(2)O}(n) or {[Cd(BBA)(2)(H(2)O)(2)]·4H(2)O}(n), where BBA is 3,5-bis-(iso-nicotin-amido)-benzoate, is isotypic with its Mn isologue [Chen et al. (2009 ▶). J. Coord. Chem.62, 2421-2428]. The cation sits on a twofold axis and is six-coordinated in a slightly distorted octa-hedral geometry; the polyhedra are linked into zigzag chains, which are further connected by N-H⋯O, O-H⋯O and O-H⋯N hydrogen bonds as well as π-π inter-actions [centroid-centroid distance of 3.639 (2) Å], giving a three-dimensional supra-molecular framework.

Aqua-bis(1H-imidazole-κN)bis-(4-methyl-benzoato-κO,O')cadmium(II).

Project description:In the title compound, [Cd(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(H(2)O)], the Cd(II) atom is coordinated by four carboxyl-ate O atoms from two bidentate chelating 4-methyl-benzoate ligands, two N atoms from two imidazole ligands and one water mol-ecule in a distorted penta-gonal bipyramidal geometry. Inter-molecular O-H⋯O hydrogen bonds between the coordinated water mol-ecule and the carboxyl-ate O atoms of 4-methyl-benzoate lead to an infinite chain. These chains are further self-assembled into a two-dimensional layer through N-H⋯O hydrogen bonds between the imidazole ligands and carboxyl-ate groups. One of the imidazole ligands is disordered over two positions with site-occupancy factors of 0.737 (4) and 0.263 (4).
