Bis[?-N'-acetyl-1-oxidonaphthalene-2-carbohydrazidato(3-)]tetra-pyridine-tricopper(II).

ABSTRACT: There are two half-mol-ecules in the asymmetric unit of the title compound, [Cu(3)(C(13)H(9)N(2)O(3))(2)(C(5)H(5)N)(4)], and crystallographic inversion symmetry completes each trinuclear mol-ecule. In both mol-ecules, the central Cu atom (site symmetry ) adopts a distorted trans-CuO(2)N(4) octa-hedral geometry, arising from its coordination by two N,O-bidentate aroylhydrazine ligands and two pyridine mol-ecules. The peripheral Cu atoms adopt trans-CuN(2)O(2) square-planar coordinations arising from an N,O,O-tri-dentate ligand (that also bonds to the central Cu atom) and a pyridine mol-ecule.

Bis[μ-N'-isobutyryl-1-oxidonaphtha-lene-2-carbohydrazidato(3-)]dipyridine-tricopper(II).

Project description:The complete mol-ecule of the title complex, [Cu(3)(C(15)H(13)N(2)O(3))(2)(C(5)H(5)N)(2)], is generated by crystallographic twofold symmetry, with the central Cu atom lying on the rotation axis: it is coordinated by two N,O-bidentate ligands in a trans-CuN(2)O(2) distorted square-planar arrangement. The other Cu atom is coordinated by an N,O,O'-tridentate ligand and a pyridine mol-ecule in a distorted trans-CuN(2)O(2) arrangement. In the crystal structure, a C-H⋯π inter-action occurs.

Tetra-pyridine-bis(trichloro-acetato)nickel(II).

Project description:The title compound, [Ni(C(2)Cl(3)O(2))(2)(C(5)H(5)N)(4)], was prepared by the reaction of pyridine and trichloro-acetatonickel(II) in ethanol solution at room temperature. The Ni(II) atom is located on a twofold rotation axis and has a slightly distorted octa-hedral coordination made up of four N atoms of the pyridine ligands and two O atoms of trichloro-acetate anions. The mol-ecular structure and packing are stabilized by intra- and inter-molecular C-H?O hydrogen-bonding inter-actions.

Tetra-aqua-bis(1,10-phenanthroline)bis-[?(2)-1H-pyrazole-3,5-dicarboxyl-ato(3-)]tricopper(II) dihydrate.

Project description:The title compound, [Cu(3)(C(5)HN(2)O(4))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)]·2H(2)O, is a trinuclear copper(II) complex in which two centrosymmetrically related pyrazole-3,5-dicarboxyl-ate(3-) and 1,10-phenanthroline ligands bind three Cu(II) atoms, with one Cu(II) atom located on a center of symmetry. In each complex, there are four coordinated water mol-ecules and two solvent water mol-ecules, which participate in extensive hydrogen-bond patterns. These inter-actions, as well as ?-? inter-actions between neighbouring 1,10-phenanthroline ligands [shortest atom-to-atom distance = 3.363?(3)?Å], extend the crystal structure into a three-dimensional supra-molecular network.

Project description:In the title compound, [Ni(C(5)H(5)N)(2)(H(2)O)(4)](NO(3))(2), the Ni(II) ion is coordinated by two N-bonded pyridine ligands and four water mol-ecules in an octa-hedral coordination mode. The asymmetric unit consists of one Ni(II) ion located on an inversion center, as well as one pyridine ligand, one nitrate anion and two water mol-ecules in general positions. In the crystal structure, the discrete complex cations and nitrate anions are connected by O-H⋯O and C-H⋯O hydrogen bonds.

The crystal packing is characterized by a C-H?O hydrogen-bonded ribbon structure approximately parallel to [10[Formula: see text]].

Bis(3-acetyl-pyridine-?N)diaqua-bis-(seleno-cyanato-?N)cobalt(II).

Project description:In the crystal structure of the title compound, [Co(NCSe)(2)(C(7)H(7)NO)(2)(H(2)O)(2)], the Co(2+) cation is coordinated by two seleno-cyanate anions, two 3-acetyl-pyridine ligands and two water mol-ecules within a slightly distorted CoN(4)O(2) octa-hedron. The asymmetric unit consists of one Co(2+) cation, which is located on a center of inversion, as well as one seleno-cyanate anion, one 3-acetyl-pyridine ligand and one water mol-ecule in general positions. Whereas one of the water H atoms makes a classical O-H?O hydrogen bond, the other shows a O-H?Se inter-action.

Disodium tricopper(II) tetra-kis[selenate(IV)] tetra-hydrate.

Project description:The title compound, Na(2)Cu(3)(SeO(3))(4)(H(2)O)(4), has been prepared under hydro-thermal conditions. The crystal structure contains a three-dimensional anionic framework made up from distorted [CuO(4)(H(2)O)(2)] octa-hedra ( symmetry), [CuO(4)(H(2)O)] square pyramids and trigonal-pyramidal SeO(3) units sharing common corners. The connectivity among these units leads to four- and eight-membered polyhedral rings, which by edge-sharing inter-connect into walls. A rhombus-like 16-membered polyhedral ring channel system with a longest length of approximately 14.0 Å and a shortest length of 5.3 Å is enclosed by such walls along the a axis. The water mol-ecules attached to the Cu atoms, as well as the electron lone pairs of the Se(IV) atoms, protrude into these channels. The seven-coordinated Na(+) counter-cations occupy the remaining free space of the 16-membered polyhedral ring channels. An intricate network of O-H⋯O hydrogen bonds further consolidates the three-dimensional structure.

Poly[tetra-μ(1,1)-azido-bis-(μ(2)-pyrimidine-2-carboxyl-ato)tricopper(II)].

Project description:In the title compound, [Cu(3)(C(5)H(3)N(2)O(2))(2)(N(3))(4)](n), one of the Cu(II) atoms lies on an inversion centre and is octa-hedrally coordinated by two bidentate chelating pyrimidine-2-carboxyl-ate ligands and two azide anions, each of which gives an N:N-bridge to the second inversion-related Cu(II) centre in the formula unit. The second Cu(II) atom is five-coordinated with a distorted square-pyramidal coordination sphere comprising a single bidentate chelating pyrimidine-2-carboxyl-ate anion and three azide N anions, two of which doubly bridge centrosymmetric Cu(II) centres, giving a two-dimensional network structure extending parallel to (010).

Tetra-aqua-bis(pyridine-3-sulfonato-κN)nickel(II).

Project description:In the mol-ecule of the title compound, [Ni(C(5)H(4)NO(3)S)(2)(H(2)O)(4)], the Ni(II) cation is located on an inversion center and is coordinated by four water mol-ecules and two pyridine-3-sulfonate anions with an NiN(2)O(4) distorted octa-hedral geometry. The face-to-face separation of 3.561 (5) Å between parallel pyridine rings indicates the existence of weak π-π stacking between the pyridine rings. The structure also contains inter-molecular O-H⋯O hydrogen bonding and weak C-H⋯O hydrogen bonding.

Hexaaqua-nickel(II) tetra-aqua-bis-(?-pyridine-2,6-dicarboxyl-ato)bis-(pyridine-2,6-dicarboxyl-ato)trinickelate(II) octa-hydrate.

Project description:The title compound, [Ni(H(2)O)(6)][Ni(3)(C(7)H(3)NO(4))(4)(H(2)O)(4)]·8H(2)O, was obtained by the reaction of nickel(II) nitrate hexa-hydrate with pyridine-2,6-dicarb-oxy-lic acid (pydcH(2)) and 1,10-phenanothroline (phen) in an aqueous solution. The latter ligand is not involved in formation of the title complex. There are three different Ni(II) atoms in the asymmetric unit, two of which are located on inversion centers, and thus the [Ni(H(2)O)(6)](2+) cation and the trinuclear {[Ni(pydc)(2)](2)-?-Ni(H(2)O)(4)}(2-) anion are centrosymmetric. All Ni(II) atoms exhibit an octa-hedral coordination geometry. Various inter-actions, including numerous O-H?O and C-H?O hydrogen bonds and C-O?? stacking of the pyridine and carboxyl-ate groups [3.570?(1), 3.758?(1) and 3.609?(1)?Å], are observed in the crystal structure.
