Bis(?-5-nitro-2-oxidobenzoato)bis-[triaqua-zinc(II)].

ABSTRACT: The title complex mol-ecule, [Zn(2)(C(7)H(3)NO(5))(2)(H(2)O)(6)], is a centrosymmetric dimer containing two zinc(II) cations with distorted octa-hedral geometries provided by the O atoms of three water mol-ecules and the two bridging bidentate 5-nitro-salicylate ligands. The separation between the metal centres in the dimer is 3.1790?(11)?Å. The crystal structure is stabilized by O-H?O hydrogen bonds, one of which intra-dimeric, linking the dimers into a three-dimensional network.

Project description:In the title compound, [Zn(C(8)H(3)NO(6))(C(10)H(8)N(2))(H(2)O)(3)]·H(2)O, the Zn(II) cation is hexa-coordinated by a chelating 2,2'-bipyridine ligand, one carboxyl-ate O atom from a 5-nitro-isophthalate dianion and three water mol-ecules in a slightly distorted octa-hedral geometry. The structure contains isolated neutral complexes, in contrast to coordination polymers formed by Mn(II), Co(II) and Cu(II) with the same ligand set. An extensive network of hydrogen bonds is formed between the water mol-ecules and the carboxyl-ate groups.

(?-4,4'-Bipyridine-?N:N')bis-[triaqua-(4,4'-bipyridine-?N)(3-nitro-phthalato-?O)cobalt(II)].

Project description:The title binuclear complex, [Co(2)(C(8)H(3)NO(6))(2)(C(10)H(8)N(2))(3)(H(2)O)(6)], has been synthesized hydro-thermally from 3-nitro-phthalic acid (H(2)NPA), Co(NO(3))(2)·6H(2)O and 4,4'-bipyridine (4,4'-bipy). The mol-ecule of the complex occupies a special position on an inversion centre. The Co(II) atom has a slightly distorted octa-hedral environment formed by two N atoms from two 4,4'-bipy ligands, one carboxyl-ate O atom from NPA, and three O atoms of water mol-ecules. An extensive O-H?O and N-H?O hydrogen-bonding system links mol-ecules of the complex into a three-dimensional network.

Bis(3-hydroxy-pyridine-?N)bis-(3-nitro-benzoato-?O)zinc(II).

Project description:The title complex, [Zn(C(7)H(4)NO(4))(2)(C(5)H(5)NO)(2)], has site symmetry 2. The Zn(II) ion is located on a crystallographic twofold rotation axis and assumes a distorted tetra-hedral ZnN(2)O(2) coordination geometry. Mol-ecules are linked by an inter-molecular O-H?O hydrogen bond and ?-? stacking inter-actions between pyridine rings [centroid-centroid speparation 3.594?(1)?Å].

Bis[μ-5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolato-κN,N:N]bis-[triaqua-zinc(II)].

Project description:In the title complex, [Zn(2)(C(7)H(3)N(5)O(2))(2)(H(2)O)(6)], the 5-(5-carboxyl-ato-3-pyrid-yl)tetra-zolate ligand chelates the Zn(II) center through one pyridyl N and one tetra-zolate N atom, and uses another N atom to bridge to the second Zn atom, forming a centrosymmetric dinuclear unit. Three coordinated water mol-ecules complete the distorted octa-hedral geometry of the Zn(II) atom. O-H⋯O and O-H⋯N hydrogen bonds involving the coordinated water mol-ecules, tetra-zolate N atoms and the carboxyl-ate group result in a three-dimensional structure.

Bis(μ-4-chloro-2-oxidobenzoato)bis-[(1,10-phenanthroline)copper(II)] dihydrate.

Project description:The structure of the the title compound, [Cu(2)(C(7)H(3)ClO(3))(2)(C(12)H(8)N(2))(2)]·2H(2)O, consists of a dimeric unit involving a planar Cu(2)O(2) group arranged around an inversion center. The coordination sphere of the Cu(II) atom can be described as an elongated distorted square pyramid where the basal plane is formed by the two N atoms of the 1,10-phenanthroline mol-ecule and the two O atoms of the hydroxy-chloro-benzoate (hcbe) anion. The long apical Cu-O distance of 2.569 (2) Å involves the O atom of a symmetry-related hcbe anion, building up the dinuclear unit. Each dinuclear unit is connected through O-H⋯O hydrogen bonds involving two water mol-ecules, resulting in an R(4) (2)(8) graph-set motif and building up an infinite chain parallel to (10). C-H⋯O inter-actions further stabilize the chain.

Bis[?-5-(2-pyrid-yl)tetra-zolato]-?N,N:N;?N:N,N-bis-[triaqua-zinc(II)] bis-(trifluoro-acetate) monohydrate.

Project description:The title compound, [Zn(2)(C(6)H(4)N(5))(2)(H(2)O)(6)](CF(3)CO(2))(2)·H(2)O, was synthesized by hydro-thermal reaction of ZnBr(2), CF(3)COOH and 2-(2H-tetra-zol-5-yl)pyridine. The Zn(II) cation is coordinated by one N atom from the 5-(2-pyrid-yl)tetra-zolate anion, two N atoms from another 5-(2-pyrid-yl)tetra-zolate anion and three O atoms from three water mol-ecules in a distorted octa-hedral geometry. The tetra-zole ligands bridge the metal ions of the dimeric structure, and the dimers are located on crystallographic inversion centers. An inter-stitial solvent water mol-ecule is located on a crystallographic mirror plane, and the CF(3)COO(-) counter-anions are also not coordinated to the metal complex. The F atoms of the anions are disordered with the F atoms statistically distributed over two positions in a 0.56?(3)/0.44?(3) ratio. All the water H atoms are involved in O-H?N and O-H?O hydrogen bonds with uncoordinated water O atoms, carboxyl-ate O atoms and tetra-zole N atoms. The inter-actions link the mol-ecules into a three-dimensional network.
