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 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.

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)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 π-π 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-κO,N,O)manganate(II) trihydrate.

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 π-π [centroid-centroid distances in the range 3.3704 (12) to 3.8674 (13)Å] and C=O⋯π [3.563 Å] inter-actions, which lead to the formation of a three-dimensional supra-molecular network.

Bis(9-amino-acridinium) bis-(pyridine-2,6-dicarboxyl-ato-κO,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. N-H⋯O hydrogen bonds connect the stacks of anions and cations in the structure. Other inter-molecular inter-actions, including weak C-H⋯O hydrogen bonds, π-π [shortest centroid-centroid distance = 3.336 (7) Å] and C-O⋯π [O⋯centroid distance = 3.562 (10) Å] inter-actions, connect the various components.

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⋯π [O⋯π = 3.099 (2) Å] and π-π 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.
