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

ABSTRACT: 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.

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.

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.

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(9-amino-acridinium) bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)nickelate(II) trihydrate.

Project description:The title compound, (C(13)H(11)N(2))(2)[Ni(C(7)H(3)NO(4))(2)]·3H(2)O, consists of a mononuclear anionic complex, two 9-amino-acridinium cations and three uncoordinated water mol-ecules. Two pyridine-2,6-dicarboxyl-ate (pydc) ligands are bound to the Ni(II) ion, giving an NiN(2)O(4) bonded set. The coordination geometry around the Ni(II) atom is distorted octa-hedral. There are two types of robust O-H?O hydrogen-bond synthons, namely R(6) (6)(24) and R(2) (4)(8), which link the complex anions and water mol-ecules to each other.

Project description:The asymmetric unit of the title compound, (C(13)H(11)N(2))(2)[Mn(C(7)H(3)NO(4))(2)]·3H(2)O, consists of a discrete mononuclear [Mn(2,6-pydc)(2)](2-) anionic complex (2,6-pydc is pyridine-2,6-dicarboxyl-ate) associated with two 9-amino-acridinium counter-ions for neutralization of charge and three uncoordin-ated water mol-ecules. The Mn(II) atom is six-coordinated by (2,6-pydc)(2-) anions in a tridentate fashion and is at the centre of a distorted octa-hedron formed by the MnO(4)N(2) bonding set. In the crystal, various inter-molecular inter-actions between different moieties can be found, such as different kinds of hydrogen bonds, offset or slipped ?-? [centroid-centroid distances in the range 3.3704?(12) to 3.8674?(13)Å] and C=O?? [3.563?Å] inter-actions, which lead to the formation of a three-dimensional supra-molecular network.

Poly[propane-1,3-diammonium [cuprate(II)-bis-(μ(2)-pyridine-2,3-dicarboxyl-ato)] trihydrate].

Project description:The title polymeric compound {(C(3)H(12)N(2))[Cu(C(7)H(3)NO(4))(2)]·3H(2)O}(n) or {(pnH(2))[Cu(py-2,3-dc)(2)]·3H(2)O}(n) (pn is propane-1,3-diamine and py-2,3-dcH(2) is pyridine-2,3-dicarboxylic acid), was synthesized by reaction of copper(II) chloride dihydrate with a proton-transfer compound, propane-1,3-diammonium pyridine-2,3-dicarboxyl-ate or (pnH(2))(py-2,3-dc), in aqueous solution. The anion is a six-coordinate complex (site symmetry ), with a distorted octa-hedral geometry around Cu(II), consisting of two bidentate pyridine-2,3-dicarboxyl-ate groups and two O atoms of bridging ligands from (py-2,3-dc)(2-) fragments, which are located in trans positions. The (pnH(2))(2+) cation is disordered over two sites by the center of inversion. Inter-molecular hydrogen bonds, π-π [centroid-centroid distances of 3.539 (3) Å] and C-O⋯π stacking inter-actions [O⋯Cg = 3.240 (5) Å; Cg is the center of the pyridine ring], connect the various components into a supra-molecular structure.

Hydroxonium creatininium bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)cobaltate(II) trihydrate.

Project description:The title compound, (C(4)H(8)N(3)O)(H(3)O)[Co(C(7)H(3)NO(4))(2)]·3H(2)O, contains a protonated creatininium cation, a hydrox-onium (H(3)O)(+) cation, a [Co(pydc)(2)](2-) (pydcH(2) = pyridine-2,6-dicarboxylic acid) complex anion, and three uncoordinated water mol-ecules. The Co(II) atom is coordinated by four O and two N atoms from two pydc ligands in a distorted octa-hedral environment. The structure also contains three uncoordinated water mol-ecules. Extensive inter-molecular O-H?O, N-H?O and C-H?O hydrogen bonds, ?-? stacking inter-actions [centroid-centroid distances = 3.565?(14) and 3.425?(14)?Å] and O?? inter-actions [O?centroid distance = 3.480?(2)?Å] connect the various components in 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.

Hydroxonium creatininium bis-(pyridine-2,6-dicarboxyl-ato-?O,N,O)nickel-ate(II) trihydrate.

Project description:The title compound, (C(4)H(8)N(3)O)(H(3)O)[Ni(C(7)H(3)NO(4))(2)]·3H(2)O, exhibits isotypism with its Co(II) analogue. All intramolecular distances and angles are similar for the two structures. This applies also for the intermolecular forces, consisting of O-H?O and N-H?O hydrogen bonds and ?-? interactions [with centroid-centroid distances of 3.428?(2) and 3.579?(2)?Å], that lead to a cohesion of the structure.
