Cyclo-Tetra-kis(?-naphthalene-1,8-dicarboxyl-ato)tetra-kis-[diaqua-(2,2'-bipyridine)-manganese(II)] tetra-hydrate.

ABSTRACT: In the title centrosymmetric tetra-nuclear complex, [Mn(4)(C(12)H(6)O(4))(4)(C(10)H(8)N(2))(4)(H(2)O)(8)]·4H(2)O, two independent Mn(II) ions are coordinated in a slightly disorted octa-hedral environment by two aqua ligands, two naphthalene-1,8-dicarboxyl-ate (1,8-nap) ligands and one bis-chelating 2,2'-bipyridine (2,2'-bipy) ligand. In the crystal, mol-ecules are linked by inter-molecular O-H?O hydrogen bonds into chains along [100]. These chains are further linked by weak ?-? inter-actions with centroid-centroid distances in the range of 3.609?(2)-3.758?(1)?Å, forming a three-dimensional supra-molecular network.

Poly[diaqua-penta-kis(?(4)-benzene-1,2-dicarboxyl-ato)(?(3)-benzene-1,2-dicarboxyl-ato)tetra-thulium(III)].

Project description:The title compound, [Tm(4)(C(8)H(4)O(4))(6)(H(2)O)(2)](n), has been synthesized hydro-thermally. The asymmetric unit has four unique Tm(III) ions that are six-, seven-, eight- and nine-coordinate. The cations are inter-connected by bridging benzene-1,2-dicarboxyl-ate (BDC) anions to form an infinite two-dimensional framework, in which the BDC ligands adopt three different coordination modes. Adjacent sheets are further packed to form a three-dimensional supra-molecular framework through O-H?O hydrogen bonds.

Project description:In the crystal structure of the title compound, {[Fe(2)(C(7)H(3)NO(4))(2)(H(2)O)(6)]·4H(2)O}(n), there are two types of coordination for the Fe(II) atoms. One Fe(II) atom is in a distorted octa-hedral N(2)O(4) environment, with two chelating rings from the pyridine-dicarboxyl-ate ligands and two O atoms from the water mol-ecules, while the other is in a distorted octa-hedral O(6) environment with two O atoms from the pyridine-dicarboxyl-ate ligands and four O atoms from the water mol-ecules. Both Fe(II) atoms lie on crystallographic centers of symmetry. The complex possesses an infinite chain structure running along the [101] direction. These chains are inter-connected by the uncoordinated water mol-ecules through O-H⋯O hydrogen bonds.

Diaqua-(2,2'-bipyridine-6,6'-dicarboxyl-ato)nickel(II).

Project description:In the title compound, [Ni(C(12)H(6)N(2)O(4))(H(2)O)(2)], the Ni(II) atom (site symmetry 2) displays a distorted cis-NiN(2)O(4) octa-hedral coordination geometry with two N atoms and two O atoms of the tetra-dentate 2,2'-bipyridine-6,6'-dicarboxyl-ate ligand in the equatorial plane and two water mol-ecules in axial positions. The complete dianionic ligand is generated by crystallographic twofold symmetry. In the crystal, a two-dimensional supra-molecular structure parallel to (001) is formed through O-H?O hydrogen-bond inter-actions between the coordinated water mol-ecules and the O atoms of nearby carboxyl-ate groups.

Diaqua-(2,2'-bipyridine-5,5'-dicarboxyl-ato-?N,N')(ethyl-enediamine-?N,N')copper(II) 2.5-hydrate.

Project description:In the mol-ecule of the title compound, [Cu(C(12)H(6)N(2)O(4))(C(2)H(8)N(2))(H(2)O)(2)]·2.5H(2)O, the Cu(II) atom is six-coordinated in a distorted octa-hedral configuration by two N atoms from a 2,2'-bipyridine-5,5'-dicarboxyl-ate anion, two N atoms from ethyl-enediamine and two O atoms from two water mol-ecules. There are also two and a half water mol-ecules in the asymmetric unit. The planar five-membered ring is nearly coplanar with the adjacent pyridine rings, while the other five-membered ring adopts a twisted conformation, probably due to hydrogen bonding. In the crystal structure, intra- and inter-molecular N-H?O and O-H?O hydrogen bonds link the mol-ecules.

Poly[[dodeca-aqua-bis-(?(3)-pyridine-2,6-dicarboxyl-ato)tetra-kis-(?(2)-pyridine-2,6-dicarboxyl-ato)tri-calciumdieuropium(III)] 10.5-hydrate].

Project description:In the title compound, {[Ca(3)Eu(2)(C(7)H(3)NO(4))(6)(H(2)O)(12)]·10.5H(2)O}(n), the Eu(III) ion is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate (PDA) ligands, forming a [Eu(PDA)(3)](3-) building block. The Ca(2+) ions adopt two types of coordination geometries. One Ca(2+) ion, lying on a twofold rotation axis, is eight-coordinated by four carboxyl-ate O atoms from four PDA ligands and four water mol-ecules, and the other two Ca(2+) ions, each lying on an inversion center, are six-coordinated by two carboxyl-ate O atoms from two PDA ligands and four water mol-ecules. The carboxyl-ate groups bridge the Eu(III) and Ca(2+) ions into a three-dimensional porous framework, with channels extending along [010] and [001] in which lattice water mol-ecules are located. Two of the lattice water mol-ecules are disordered over two sets of sites with equal occupancy and one water mol-ecule is 0.25-occupied. Numerous O-H?O hydrogen bonds involving the water mol-ecules and carboxyl-ate O atoms are present.

Tetra-kis(1,10-phenanthroline)bis-(?-pyridine-2,6-dicarboxyl-ato)(pyridine-2,6-di-carboxyl-ato)dicopper(II)terbium(III) nitrate tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Cu(2)Tb(C(7)H(3)NO(4))(3)(C(12)H(8)N(2))(4)]NO(3)·4H(2)O, consists of one-half of the C(2)-symmetric trinuclear coordination cation, one-half of the C(2)-symmetric nitrate anion and two water mol-ecules. In the coordination cation, the Cu(II) atom is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from a bridging-chelating carboxyl-ate group of the pyridine-2,6-dicarboxyl-ate anion, completing a distorted N(4)O(2) octa-hedral coordination environment. The Tb(III) atom, located on a twofold rotation axis, is nine-coordinated by three tridentate pyridine-2,6-dicarboxyl-ate anions forming an N(3)O(6) donor set. The intra-molecular Cu?Tb distance of 5.0592?(11)?Å indicates weak inter-actions between the Cu(II) and Tb(III) atoms. The coordination cations, nitrate anions and water mol-ecules are connected via O-H?O hydrogen bonds into layers parallel to the (001) plane. Moreover, there are extensive ?-? stacking inter-actions [centroid-centroid distances = 4.332?(7) and 3.878?(5)?Å] between the phenanthroline ligands and between phenanthroline and pyridine-2,6-dicarboxyl-ate ligands.

Tetra-kis(2,4,6-triamino-1,3,5-triazin-1-ium) tris-(pyridine-2,6-dicarboxyl-ato)calcate(II) hexa-hydrate.

Project description:The title compound, (C(3)H(7)N(6))(4)[Ca(C(7)H(3)NO(4))(3)]·6H(2)O or (tataH)(4)[Ca(pydc)(3)]·6H(2)O (where tata is 2,4,6-triamino-1,3,5-triazine and pydcH(2) is pyridine-2,6-dicarboxylic acid), was obtained by reaction of Ca(NO(3))(2)·4H(2)O with the proton-transfer compound (tataH)(2)(pydc) in aqueous solution. The [Ca(pydc)(3)](4-) anion has twofold crystallographic symmetry. It is a nine-coordinate Ca(II) complex with a distorted tricapped trigonal-prismatic coordination geometry. The structure also contains four tataH(+) cations and six uncoordinated water mol-ecules. There are extensive O-H⋯O, O-H⋯N, N-H⋯O, N-H⋯N and C-H⋯O hydrogen bonds in the crystal structure.

Poly[(μ-4,4'-bipyridine)(μ-naphthalene-1,4-dicarboxyl-ato)manganese(II)].

Project description:In the crystal structure of the title compound, [Mn(C(12)H(6)O(4))(C(10)H(8)N(2))](n), the Mn atoms are each coordinated by four O atoms of naphthalene-1,4-dicarboxyl-ate anions and two N atoms of two symmetry-related 4,4'-bipyridine ligands within a strongly distorted octa-hedra. Two of the O atoms originate from one naphthalene-1,4-dicarboxyl-ate anion, whereas the remaining two O atoms derive from two symmetry-equivalent naphthalene-1,4-dicarboxyl-ate anions. Two Mn atoms are connected via the anions into dimers, which are further linked by the anions and the N-donor ligands into a three-dimensional coordination network.

catena-Poly[diaqua-(cis-cyclo-hexane-1,2-dicarboxyl-ato)cadmium].

Project description:In the title polymer, [Cd(C(8)H(10)O(4))(H(2)O)(2)](n), the Cd(II) cation is coordinated by five carboxyl-ate O atoms from three different cyclo-hexane-1,2-dicarboxyl-ate anions and two O atoms from two water mol-ecules, displaying a distorted CdO(7) pentagonal-bipyramidal geometry. Each anion acts as a ?(3)-bridge, linking symmetry-related Cd(II) ions into a layer parallel to (010). In the crystal, numerous O-H?O and C-H?O hydrogen bonds occur. The coordinated water mol-ecules and carboxyl-ate O atoms act as donors or acceptors in the formation of these hydrogen-bonding inter-actions.
