Catena-Poly[[[di-?(2)-hydroxido-bis-[(di-2-pyridylamine)nickel(II)]]-?-fumarato] dihydrate].

ABSTRACT: The Ni(II) ion in the one-dimensional title complex, {[Ni(2)(C(4)H(2)O(4))(OH)(2)(C(10)H(9)N(3))(2)]·2H(2)O}(n), has a distorted square-pyramidal coordination environment formed by three O atoms from two bridging hydroxide groups and one carboxyl-ate group of the fumarate ligand and two pyridine N atoms from a di-2-pyridylamine (dpa) ligand. Two hydroxide groups link adjacent metal centers, forming a centrosymmetric four-membered [Ni(2)(OH)(2)] ring. In the crystal structure, the H atoms of the bridging hydroxide groups form inter-molecular hydrogen bonds to both water mol-ecules. These are further linked to the uncoordinated O atoms of the carboxyl-ate groups and the NH group of a dpa ligand to generate a three-dimensional network from the chains of the coordination polymer.

Project description:In the title compound, {[Ga(2)(C(4)H(4)O(6))(2)(OH)(2)]·2H(2)O}(n), the Ga(III) atom is located on a twofold rotation axis and is six-coordinated by two O atoms from bridging hydroxide groups and four O atoms from two symmetry-related tartrate units in a slightly distorted octa-hedral environment. Each tartrate unit binds to two Ga(III) atoms as a bis-chelating bridging ligand by two pairs of hydroxide groups and an O atom of a carboxyl-ate group. The Ga(III) atoms are linked by two bridging hydroxide groups located on mirror planes. In this way a chain along the c axis is formed. Free water mol-ecules on mirror planes are located between the chains and hold them together through hydrogen-bonding inter-actions, with O⋯O distances in the range 2.509 (3)-3.179 (5) Å.

catena-Poly[[[diaqua-(di-2-pyridylamine-?N,N')nickel(II)]-?-fumarato-?O:O] tetra-hydrate].

Project description:In the crystal structure of the title compound, {[Ni(C(4)H(2)O(4))(C(10)H(9)N(3))(H(2)O)(2)]·4H(2)O}(n), zigzag chains are built up from cis-[Ni(dpya)(H(2)O)(2)](2+) cations (dpya is di-2-pyridylamine) linked by bis-monodentate coordinated bridging fumarate ligands. The Ni(II) atom is coordinated by one chelating dpya ligand, two aqua ligands in trans positions and two monodentate fumarate ligands in cis positions in the form of a deformed octa-hedron. The water mol-ecules, O atoms of the fumarate carboxyl-ate groups and the amine group of the dpya ligand are involved in an extended network of intra- and inter-molecular O-H?O hydrogen bonds. Moreover, ?-? inter-actions between the pyridine rings of the dpya ligand contribute to the stability of the structure. Two of the five uncoordinated water molecules are half-occupied.

catena-Poly[[[diaqua-nickel(II)]-di-μ-glycine] dichloride].

Project description:In the polymeric title complex, {[Ni(C(2)H(5)NO(2))(2)(H(2)O)(2)]Cl(2)}(n), the Ni(II) atom lies on an inversion center and is in a distorted octa-hedral NiO(6) configuration, with four carboxyl-ate O atoms from four zwitterionic glycine mol-ecules forming the equatorial plane and two water O atoms occupying the axial positions. The Cl(-) counterions lie in the inter-stices. The Ni(II) complexes are linked into polymeric sheets parallel to the bc plane. These sheets are then further connected into a three-dimensional network by O-H⋯O, O-H⋯Cl and N-H⋯Cl hydrogen bonds, together with weak C-H⋯O inter-actions.

catena-Poly[[aqua-dipyridine-copper(II)]-μ-fumarato].

Project description:The title compound, [Cu(C(4)H(2)O(4))(C(5)H(5)N)(2)(H(2)O)](n), is a one-dimensional coordination polymer based on pyridine and fumarate ligands. Each Cu(II) cation is coordinated by two carboxyl-ate O atoms belonging to two fumarate anions, two N atoms from two pyridine mol-ecules and one water mol-ecule, in a square-based pyramidal geometry. Each fumarate anion bridges two Cu(II) cations through the two carboxyl-ate groups in a bis-monodentate fashion to form a one-dimensional polymeric chain along the c axis. Neighbouring chains are linked together to form a two-dimensional network parallel to the ac plane via hydrogen bonding inter-actions between uncoordinated carboxyl-ate O atoms and coordinated water mol-ecules of adjecent chains.

Project description:In the title compound, {[Ni(2)(C(7)H(3)NO(5))(2)(C(12)H(12)N(2))(H(2)O)(2)]·4H(2)O}(n), two Ni(II) ions, two tridentate pyridine-2,6-dicarboxyl-ate N-oxide ligands and two coordinated water mol-ecules form centrosymmetric dinuclear units, which are further bridged by centrosymmetric 1,2-di-4-pyridylethane ligands into polymeric chains along [210]. Each Ni(II) ion has a distorted square-pyramidal environment, with the basal plane formed by three O [Ni-O = 1.9290 (16)-1.9588 (10) Å] and one N [Ni-N = 1.9828 (18) Å] atoms and the apical position occupied by the water mol-ecule [Ni-O = 2.2643 (11) Å]. The water mol-ecules are involved in the formation of O-H⋯O hydrogen bonds.

catena-Poly[{di-μ-isonicotinato-bis[di-aqua-isonicotinatoeuropium(III)]}-μ-isonicotinato-[diisonicotinatocopper(II)]-μ-isonicotinato].

Project description:The title compound, [CuEu(2)(C(6)H(4)NO(2))(8)(H(2)O)(4)](n), displays a one-dimensional chain structure. The four-coordinate Cu(II) ion (site symmetry ) adopts a trans-CuN(2)O(2) geometry and is bridged by two carboxyl-ate groups from two isonicotinate ligands. The Eu(III) ion adopts a distorted square-anti-prismatic geometry, being coordinated by four O atoms from bridging carboxyl-ate groups of four isonicotinate ligands, two O atoms from chelating carboxyl-ate groups of one isonicotinate ligand and two O atoms from coordinated water mol-ecules; adjacent Eu(III) ions in the chain are related by inversion. The water mol-ecules interact with the ligands via O-H⋯N hydrogen bonds [O⋯O = 2.782 (3)-2.881 (3) Å], which link the chains into a three-dimensional structure.

catena-Poly[[diazido-zinc(II)]-?-di-4-pyridylamine-?N:N'].

Project description:In the title compound, [Zn(N(3))(2)(C(10)H(9)N(3))](n), tetra-hedrally coordinated Zn(II) ions with two monodentate azide ligands are linked into zigzag one-dimensional chain motifs by di-4-pyridylamine (dpa) tethers. Individual [Zn(N(3))(2)(dpa)](n) chains are connected into supra-molecular layers via N-H?N hydrogen bonding between the central amine groups of the dpa ligands and terminal unligated azide N atoms. The azide ligands in one supra-molecular layer penetrate through the neighboring layers above and below, allowing stacking into a three-dimensional structure.

Project description:The title compound, {[Tm(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(2)]·2H(2)O}(n), is isotypic with the analogous Tb(III) compound [Li et al. (2009 ▶). Acta Cryst. E65, m410]. All interatomic distances and angles and the hydrogen-bond geometries are very similar for the two structures. The refined Flack parameter of 0.49 (2) suggests inversion twinning.

catena-Poly[[[diaqua-terbium(III)]-μ-6-carboxy-nicotinato-μ-pyridine-2,5-di-carboxyl-ato] dihydrate].

Project description:The title compound, {[Tb(C(7)H(3)NO(4))(C(7)H(4)NO(4))(H(2)O)(2)]·2H(2)O}(n), is isotypic with the analogous Tm(III) compound [Li, Zhang, Wang & Bai (2009). Acta Cryst. E65, m411]. The Tb(III) atom is octa-coordinated by two water mol-ecules and by four carboxyl-ate O atoms and two pyridyl N atoms from two pyridine-2,5-dicarboxyl-ate (2,5-pydc) and two 6-carboxy-nicotinate (2,5-Hpydc) ligands. The 2,5-pydc and 2,5-Hpydc ligands bridge Tb(III) atoms, generating helical coordination polymers along [001]. An extensive network of O-H⋯O hydrogen bonds is formed between the coordination polymers and the uncoordinated water mol-ecules. The refined Flack parameter of 0.54 (2) suggests inversion twinning.

catena-Poly[[bis-(μ-3-carboxy-benzoato)bis-(1,10-phenanthroline)tricopper(II)]-di-μ(3)-isophthalato].

Project description:The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions. The trinuclear unit presents a central almost planar CuO(4) chromophore with the cation on a symmetry center, and two symmetry-related CuN(2)O(3) groups with the metal centre in a distorted square-pyramidal environment. These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π-π stacking inter-actions (face-to-face distance ca 3.45 Å) and O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.
