Bis(2,6-diamino-pyridinium) bis-(pyridine-2,6-dicarboxyl-ato)zincate(II) monohydrate.

ABSTRACT: In the title hydrated mol-ecular salt, (C(5)H(8)N(3))(2)[Zn(C(7)H(3)NO(4))(2)]·H(2)O, the Zn(II) atom is coordinated by two O,N,O'-tridentate pyridine-2,6-dicarboxyl-ate dianions, generating a slightly distorted trans-ZnN(2)O(4) octa-hedral coordination geometry for the metal ion. In the crystal, a network of O-H?O, N-H?O and C-H?O hydrogen bonds involving the cations, anions and water mol-ecules results in a three-dimensional network.

Project description:In the title compound, (C(13)H(11)N(2))(2)[Zn(C(7)H(3)NO(4))(2)]·3H(2)O, the Zn(II) ion is six-coordinated with the N(4)O(2) donor set being a distorted octa-hedron through two almost perpendicular (r.m.s. deviation of ligand atoms from the mean plane is 0.057?Å) tridentate pyridine-2,6-dicarboxyl-ate ligands [dihedral angle between the ligands = 86.06?(4)°]. The charge is compensated by two 9-amino-acridinium cations protonated on the ring N atom. A variety of inter-molecular contacts, such as ion-ion, N-H?O and O-H?O hydrogen bonds, and ?-? stacking [centroid-centroid distances = 3.4907?(9)-4.1128?(8)?Å], between cations and between anions, play important roles in the formation of the three-dimensional network.

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.

3-(Amino-carbon-yl)pyridinium diaqua-bis-(pyridine-2,6-dicarboxyl-ato)bis-muthate(III) monohydrate.

Project description:The asymmetric unit of the ionic title compound, (C(6)H(7)N(2)O)[Bi(C(7)H(3)NO(4))(2)(H(2)O)(2)]·H(2)O or (acpyH)[Bi(pydc)(2)(H(2)O)(2)]·H(2)O, contains an [Bi(pydc)(2)(H(2)O)(2)](-) anion (where pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid), a protonated 3-(amino-carbon-yl)pyridine as counter-ion, (acpyH)(+), and one uncoordinated water mol-ecule. The anion is an eight-coordinate complex with a square-anti-prismatic geometry around the Bi(III) atom. In the crystal, extensive O-H?O and N-H?O hydrogen bonds, as well as ion pairing, C=O?? inter-actions [O?centroid distance = 3.583?(5)?Å], ?-? stacking [centroid-centroid distance = 3.864?(3)?Å], and C-H?? and C-H?O inter-actions, play an important role in the formation and stabilization of the three-dimensional supra-molecular structure.

Bis(2-amino-4-methyl-pyridinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II).

Project description:The asymmetric unit of the title compound, (C(6)H(9)N(2))(2)[Cu(C(7)H(3)NO(4))(2)], contains half of a [Cu(pydc)(2)](2-) (pydcH(2) is pyridine-2,6-dicarb-oxy-lic acid) anion and one protonated 2-amino-4-methyl-pyridine (2a4mpH)(+) counter-ion. The anion is a six-coordinated complex with a distorted CuN(2)O(4) octa-hedral geometry around the Cu(II) ion. N-H⋯O and C-H⋯O hydrogen bonds along with π-π contacts between the pyridine rings of the (2a4mpH)(+) cations [centroid-centroid distance = 3.573 (2) Å] stabilize the crystal structure.

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.

Project description:In the centrosymmetric dinuclear complex anion of the title compound, (C(5)H(8)N(3))(2)[Bi(2)(C(7)H(3)NO(4))(4)(H(2)O)(2)]·4H(2)O, the Bi(III) atom is eight-coordinated in an N(2)O(6) environment and has a distorted bicapped trigonal-prismatic coordination environment. Extensive inter-molecular O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds lead to the stability of the crystal structure. Inter-actions between one C-H group of the 2,3-diamino-pyridinium [(2,3-dapyH)(+)] cation and the aromatic ring of the pyridine-2,6-dicarboxyl-ate (pydc) ligand (C-H⋯centroid distance = 2.78 Å) and π-π inter-actions between the (2,3-dapyH)(+) cations and between the (2,3-dapyH)(+) cation and the pydc ligand [centroid-centroid distances = 3.489 (5) and 3.694 (5) Å] are observed.

Acridinium (6-carboxy-pyridine-2-carboxyl-ato)(pyridine-2,6-dicarboxyl-ato)zincate(II) penta-hydrate.

Project description:The reaction of Zn(NO(3))(2) with pyridine-2,6-dicarboxylic acid (pydcH(2)) and acridine (acr) in aqueous solution leads to the formation of the title compound, (C(13)H(10)N)[Zn(C(7)H(3)NO(4))(C(7)H(4)NO(4))]·5H(2)O or (acrH)[Zn(pydcH)(pydc)]·5H(2)O. In the title compound, the Zn(II) atom is coordinated by four O atoms and two N atoms from the tridentate chelating rings of (pydc)(2-) and (pydcH)(-) anions. The geometry of the resulting ZnN(2)O(4) coordination can be described as distorted octa-hedral. To balance the charges, one protonated acridine (acrH)(+) cation is present. In the crystal structure, extensive O-H?O and N-H?O hydrogen bonds involving acrH(+), the complex anion and uncoordinated water mol-ecules form a three-dimensional network.

Bis(2,6-diamino-pyridinium) bis-(hydrogen oxalate) monohydrate.

Project description:The asymmetric unit of the title compound, 2C(5)H(8)N(3) (+)·2C(2)HO(4) (-)·H(2)O, contains two crystallographically independent 2,6-diamino-pyridinium cations, a pair of hydrogen oxalate anions and a water mol-ecule. Both 2,6-diamino-pyridinium cations are planar, with maximum deviations of 0.011 (2) and 0.015 (1) Å, and are protonated at the pyridine N atoms. The hydrogen oxalate anions adopt twisted conformations and the dihedral angles between the planes of their carboxyl groups are 31.01 (11) and 63.48 (11)°. In the crystal, the cations, anions and water mol-ecules are linked via O-H⋯O and N-H⋯O hydrogen bonds, forming a three-dimensional network.
