(2-Amino-pyrimidine-?N)diaqua(pyridine-2,6-dicarboxyl-ato-?O,N,O)-nickel(II) monohydrate.

ABSTRACT: The reaction of Ni(NO(3))(2)·6H(2)O with pyridine-2,6-dicarboxylic acid, NaOH and 2-amino-pyrimidine in aqueous solution leads to the formation of the title complex, [Ni(C(7)H(3)NO(4))(C(4)H(5)N(3))(H(2)O)(2)]·H(2)O. The Ni(II) ion is coordinated by one N and two O atoms of the tridentate chelating pyridine-2,6-dicarboxyl-ate anion, one heterocyclic N atom of the 2-amino-pyrimidine ligand, and two water mol-ecules. The resulting geometry for the [NiN(2)O(4)] coordination environment can be described as distorted octa-hedral. One uncoord-inated water mol-ecule completes the asymmetric unit. Extensive O-H?O and N-H?O hydrogen-bonding inter-actions between the NH(2) group of 2-amino-pyrimidine, carboxyl-ate groups, and coordinated and uncoordinated water mol-ecules contribute to the formation of a three-dimensional supra-molecular structure.

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.

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.

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.

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, 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, π-π stacking inter-actions [the shortest centroid-centroid distance is 3.350 (2) Å], and a C-O⋯π inter-action [O⋯centroid distance = 3.564 (2) Å], which connect the various components into a three-dimensional network.

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 π-π 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.

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.
