Poly[[tetra-aqua-bis-(μ(3)-pyridine-2,6-dicarboxyl-ato)(μ(2)-pyridine-2,6-dicarboxyl-ato)dilanthanum(III)] dihydrate].

Project description:There are two independent La(III) cations in the polymeric title compound, {[La(2)(C(7)H(3)NO(4))(3)(H(2)O)(4)]·2H(2)O}(n). One is nine-coordinated in an LaN(2)O(7) tricapped trigonal-prismatic geometry formed by three pyridine-2,6-dicarboxyl-ate anions and two water mol-ecules, while the other is ten-coordinated in an LaNO(9) bicapped square-anti-prismatic geometry formed by four pyridine-2,6-dicarboxyl-ate anions and two water mol-ecules. The two La(III) cations are separated by a non-bonding distance of 5.026 (3) Å. The pyridine-2,6-dicarboxyl-ate anions bridge the La(III) cations, forming a three-dimensional polymeric complex. The crystal structure contains extensive classical O-H⋯O hydrogen bonds and weak inter-molecular C-H⋯O hydrogen bonds. The crystal structure is further consolidated by π-π stacking between pyridine rings, the shortest centroid-centroid distance between parallel pyridine rings being 3.700 (5) Å.

Propane-1,2-diammonium bis-(pyridine-2,6-dicarboxyl-ato-κO,N,O')nickelate(II) tetra-hydrate.

Project description:The reaction of nickel(II) nitrate hexa-hydrate, propane-1,2-diamine and pyridine-2,6-dicarboxylic acid in a 1:2:2 molar ratio in aqueous solution resulted in the formation of the title compound, (C(3)H(12)N(2))[Ni(C(7)H(3)NO(4))(2)]·4H(2)O or (p-1,2-daH(2))[Ni(pydc)(2)]·4H(2)O (where p-1,2-da is propane-1,2-diamine and pydcH(2) is pyridine-2,6-dicarboxylic acid). The geometry of the resulting NiN(2)O(4) coordination can be described as distorted octa-hedral. Considerable C=O⋯π stacking inter-actions are observed between the carboxyl-ate C=O groups and the pyridine rings of the (pydc)(2-) fragments, with O⋯π distances of 3.1563 (12) and 3.2523 (12) Å and C=O⋯π angles of 95.14 (8) and 94.64 (8)°. In the crystal structure, a wide range of non-covalent inter-actions, consisting of hydrogen bonding [O-H⋯O, N-H⋯O and C-H⋯O, with D⋯A distances ranging from 2.712 (2) to 3.484 (2) Å], ion pairing, π-π [centroid-to-centroid distance = 3.4825 (8) Å] and C=O⋯π stacking, connect the various components to form a supra-molecular structure.

[?-1,2-Bis(4-pyrid-yl)ethene-?N:N']bis-[aqua-(pyridine-2,6-dicarboxyl-ato-?O,N,O)copper(II)] dihydrate.

Project description:In the title dinuclear Cu(II) complex, [Cu(2)(C(7)H(3)NO(4))(2)(C(12)H(10)N(2))(H(2)O)(2)]·2H(2)O, the water-coordinated Cu(II) cation is O,N,O'-chelated by a pyridine-2,6-dicarboxyl-ate (pdc) dianion, and one pyridine N atom from a 1,2-bis-(4-pyrid-yl)ethene ligand coordinates to the Cu(II) cation, completing the CuN(2)O(3) distorted square-pyriamidial geometry. The Cu-O(water) bond [2.388?(4)?Å] in the axial direction is much longer than the other Cu-O bonds. The 1,2-bis-(4-pyrid-yl)ethene ligand is located across an inversion center with the mid-point of the C=C bond at the inversion center, and bridges two Cu(II) cations, generating a centrosymmetric dinuclear complex. The crystal structure is stabilized by classical O-H?O and weak C-H?O hydrogen bonds.

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.

2,6-Diamino-pyridinium bis-(4-hydroxy-pyridine-2,6-dicarboxyl-ato-?O,N,O)ferrate(III) dihydrate.

Project description:The reaction of iron(II) sulfate hepta-hydrate with the proton-transfer compound (pydaH)(hypydcH) (pyda = pyridine-2,6-diamine; hypydcH(2) = 4-hydroxy-pyridine-2,6-dicarboxylic acid) in an aqueous solution led to the formation of the title compound, (C(5)H(8)N(3))[Fe(C(7)H(3)NO(5))(2)]·2H(2)O. The anion is a six-coordinated complex with a distorted octa-hedral geometry around the Fe(III) atom. Extensive inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds, involving the complex anion, (pydaH)(+) counter-ion and two uncoordinated water mol-ecules, and ?-? [centroid-to-centroid distance 3.323?(11)?Å] and C-O?? [O-centroid distance 3.150?(15)?Å] inter-actions connect the various components into a supra-molecular structure.

2,6-Diamino-pyridinium bis-(4-hydroxy-pyridine-2,6-dicarboxyl-ato-?O,N,O)chromate(III) dihydrate.

Project description:The reaction of chromium(III) nitrate hexa-hydrate, pyridine-2,6-diamine and 4-hydroxy-pyridine-2,6-dicarboxylic acid in a 1:2:2 molar ratio in aqueous solution resulted in the formation of the title compound, (C(5)H(8)N(3))[Cr(C(7)H(3)NO(5))(2)]·2H(2)O or (pydaH)[Cr(hypydc)(2)]·2H(2)O (where pyda is pyridine-2,6-diamine and hypydcH(2) is 4-hydroxy-pyridine-2,6-dicarboxylic acid). Each Cr(III )atom is hexa-coordinated by four O and two N atoms from two (hypydc)(2-) fragments, which act as tridentate ligands, in a distorted octa-hedral geometry. The O-Cr-O-C torsion angles between the two planes of the (hypydc)(2-) fragments [-99.81?(17) and 97.77?(17)°] indicate that these two units are almost perpendicular to one another. In the crystal structure, extensive O-H?O, N-H?O and C-H?O hydrogen bonds with D?A distances ranging from 2.560?(2) to 3.279?(3)?Å, ion pairing, C-O?? [O?? = 3.166?(2)?Å] and ?-? stacking inter-actions between (hypydc)(2-) and (pydaH)(+) rings [with a centroid-centroid distance of 3.3353?(14)?Å] contribute to the formation of a three-dimensional supra-molecular structure.

Project description:In the title compound, (C(4)H(14)N(2))[Cd(C(7)H(3)NO(4))(2)]·2H(2)O, the Cd(II) ion is coordinated by four O atoms [Cd-O = 2.2399?(17)-2.2493?(17)?Å] and two N atoms [Cd-N = 2.3113?(15) and 2.3917?(15)?Å] from two tridentate pyridine-2,6-dicarboxyl-ato ligands in a distorted octa-hedral geometry. The uncoordinated water mol-ecules are involved in O-H?O and N-H?O hydrogen bonds, which contribute to the formation of a three-dimensional supra-molecular structure, along with ?-? stacking inter-actions [centroid-centroid distances of 3.5313?(13) and 3.6028?(11)?Å between the pyridine rings of neighbouring dianions].
