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

ABSTRACT: 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 ?-? contacts between the pyridine rings of the (2a4mpH)(+) cations [centroid-centroid distance = 3.573?(2)?Å] stabilize the crystal structure.

Project description:The asymmetric unit of the title compound, (C(13)H(11)N(2))(2)[Cu(C(7)H(3)NO(4))(2)]·3H(2)O, consists of one [Cu(pydc)(2)](2-) dianion (pydc is pyridine-2,6-dicarboxyl-ate), two 9-amino-acridinum monocations and three uncoordinated water mol-ecules. The Cu(II) atom is coordinated by two pydc dianions acting as tridentate ligands, and forming five-membered chelate rings with copper(II) as the central atom. The Cu(II) atom is surrounded by four O atoms in the equatorial plane and two pyridine N atoms in axial positions, resulting in a distorted octa-hedral coordination geometry. In the crystal, there are two types of O-H?O and N-H?O hydrogen-bonding synthons linking the anionic and cationic fragments and the water mol-ecules, namely R(4) (4)(16), and R(4) (2)(8). There are also weak C-H?O hydrogen bonds, ?-? stacking inter-actions [the shortest centroid-centroid distance is 3.350?(2)?Å], and a C-O?? inter-action [O?centroid distance = 3.564?(2)?Å], which connect the various components into a three-dimensional network.

Project description: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.

Butane-1,4-diammonium bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II) trihydrate.

Project description:In the title compound, (C(4)H(14)N(2))[Cu(C(7)H(3)NO(4))(2)]·3H(2)O or (bdaH(2))[Cu(pydc)(2)]·3H(2)O (where bda is butane-1,4-diamine and pydcH(2) is pyridine-2,6-dicarboxylic acid), the Cu(II) atom is coordinated by four O atoms [Cu-O = 2.0557?(16)-2.3194?(16)?Å] and two N atoms [Cu-N = 1.9185?(18) and 1.9638?(18)?Å] from two chelating rings of the pydc(2-) anions, which act as tridentate ligands. The geometry of the resulting CuN(2)O(4) coordination can be described as distorted octa-hedral. The the two pydc(2-) fragments are almost perpendicular to one another [77.51?(11)°]. To balance the charges, two centrosymmetric protonated butane-1,4-diammonium, (bdaH(2))(2+) cations are present. In the crystal structure, extensive O-H?O, N-H?O and C-H?O hydrogen bonds [D?A = 2.720?(2)-3.446?(3)?Å], ion pairing, C-O?? [O?? = 3.099?(2)?Å] and ?-? stacking inter-actions between the pydc(2-) rings [centroid-centroid distance = 3.5334?(15)?Å] contribute to the formation of a three-dimensional supra-molecular structure.

Bis(8-hy-droxy-2-methyl-quinolinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II) methanol monosolvate monohydrate.

Project description:The title compound, (C(10)H(10)NO)(2)[Cu(C(7)H(3)NO(4))(2)]·CH(3)OH·H(2)O was prepared by the reaction of copper(II) nitrate hexa-hydrate, 8-hy-droxy-2-methyl-quinoline, and pyridine-2,6-dicarb-oxy-lic acid in a 1:2:2 molar ratio in an aqueous solution. The geometry of the resulting CuN(2)O(4) coordination can be described as distorted octa-hedral. In the crystal, there are several inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds. An intra-molecular N-H⋯O hydrogen bond occurs in one of the cations. Considerable π-π stacking inter-actions are also observed between the aromatic rings of the cations, with centroid-centroid distances of 3.4567 (13), 3.5342 (14), 3.6941 (14) and 3.4568 (13) Å. These non-covalent inter-actions connect the components, forming a three-dimensional supra-molecular structure.

Bis(9-amino-acridinium) bis-(pyridine-2,6-dicarboxyl-ato)cuprate(II) trihydrate.

Project description:The asymmetric unit of the title compound, (C(13)H(11)N(2))(2)[Cu(C(7)H(3)NO(4))(2)]·3H(2)O or (9-aminoAcr)[Cu(pydc)(2)]·3H(2)O, contains a Cu(pydc)(2) (pydc = pyridine-2,6-dicarboxyl-ate) anion, two protonated 9-amino-acridine (9-aminoAcr)(+) counter-ions and three uncoordinated water mol-ecules. The anion contains a six-coordinated Cu(II) atom within a distorted octa-hedral geometry. Non-covalent inter-actions i.e. N-H?O and O-H?O hydrogen bonds and inter-molecular ?-? contacts between the pyridine rings [centroid-centroid distance = 3.7773?(13)?Å] and acridine rings [centroid-centroid distance = 3.4897?(13), 3.7784?(14) and 3.8627?(15)?Å] result in the formation of a three-dimensional network.

Bis(2-amino-4-methyl-pyridinium) trans-diaqua-bis-(pyrazine-2,3-dicarboxyl-ato)cuprate(II) hexa-hydrate.

Project description:The title compound, (C(6)H(9)N(2))(2)[Cu(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O, consists of a mononuclear trans-[Cu(pzdc)(2)(H(2)O)(2)](2-) dianion (pzdc is pyrazine-2,3-dicarboxyl-ate) and two [ampyH](+) cations (ampy is 2-amino-4-methyl-pyridine) with six water mol-ecules of solvation. The Cu(II) atom is hexa-coordinated by two pzdc groups and two water mol-ecules. The coordinated water mol-ecules are in trans-diaxial positions and the pzdc dianion acts as a bidentate ligand through an O atom of the carboxyl-ate group and the N atom of the pyrazine ring. There are diverse hydrogen-bonding inter-actions, such as N-H?O and O-H?O contacts, which lead to the formation of a three-dimensional supra-molecular architecture.

Bis(2-amino-6-methyl-pyridinium) trans-diaqua-bis-(pyrazine-2,3-dicarboxyl-ato)cuprate(II) hexa-hydrate.

Project description:The title compound, (C(6)H(9)N(2))(2)[Cu(C(6)H(2)N(2)O(4))(2)(H(2)O)(2)]·6H(2)O, was obtained by the reaction of CuCl(2)·2H(2)O with pyrazine-2,3-dicarb-oxy-lic acid (pyzdcH(2)) and 2-amino-6-methyl-pyridine (2a-6mpy) in aqueous solution. The Cu(II) atom is located on an inversion centre and has an overall octa-hedral coordination environment. Two N and two O atoms from (pyzdc)(2-) ligands define the equatorial plane and two water mol-ecules are in axial positions, resulting in a typical tetra-gonally Jahn-Teller-distorted environment. Extensive classical O-H?O, O-H?N and N-H?O and non-classical C-H?O hydrogen bonds, as well as ?-? stacking inter-actions between aromatic rings of the cations [centroid-centroid distance = 3.58?(9)?Å], lead to the formation of a three-dimensional supra-molecular structure.

Bis(9-amino-acridinium) bis-(pyridine-2,6-dicarboxyl-ato)zincate(II) trihydrate.

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.

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.
