Piperazine-1,4-diium bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)cobaltate(II) tetra-hydrate.

ABSTRACT: The asymmetric unit of the title complex, (C(4)H(12)N(2))[Co(C(7)H(3)NO(4))(2)]·4H(2)O, consists of one piperazinediium dication, one [Co(py-2,6-dc)(2)](2-) dianion (where py-2,6-dc is pyridine-2,6-dicarboxyl-ate) and four water mol-ecules. The piperazinediium cation adopts a chair conformation and the Co(II) ion is six-coordinated in an N(2)O(4) environment, having a distorted octa-hedral geometry. In the crystal, inter-molecular O-H?O, N-H?O and weak C-H?O hydrogen bonds link the components, forming a three-dimensional network.

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.

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.

In the crystal, the components are linked by O-H?O, N-H?O and C-H?O hydrogen bonds, generating a three-dimensional network.

Tris(piperazine-1,4-diium) bis-[hexa-chloridoindate(III)] tetra-hydrate.

Project description:The asymmetric unit of the title compound, (C(4)H(12)N(2))(3)[InCl(6)](2)·4H(2)O, consists of one and half independent piperazinium cations, an hexa-chloridoindate anion and two mol-ecules of water.
