Poly[diaqua-bis-(nitrato-?²O,O')bis-(1,10-phenanthroline-?²N,N')-??-succinato-dicadmium].

ABSTRACT: In the title coordination polymer, [Cd?(C?H?O?)(NO?)?(C??H?N?)?(H?O)?](n), the Cd(II) ion is seven-coordinated within a distorted penta-gonal-bipyramidal O?N? environment. The succinate anions, located on an inversion centre, adopt a bis-monodentate bridging mode, leading to the formation of rods along [100]. The rods are connected by O-H?O hydrogen bonds between the coordinating water mol-ecules and nitrate O atoms of adjacent rods; the same type of hydrogen bonds are also observed between water and carboxyl-ate O atoms within the rods. ?-? stacking inter-actions with a minimum plane-to-plane separation of 3.462?(2)?Å occur between phenanthroline ligands.

Diaqua-bis-(perchlorato)(1,10-phenanthroline)copper(II).

Project description:In the title compound, [Cu(ClO(4))(2)(C(12)H(8)N(2))(H(2)O)(2)], the Cu(II) atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water mol-ecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN(2)O(4) octa-hedral environment. The crystal packing is stabilized by O-H?O hydrogen bonds between the water mol-ecules and the perchlorate anions. In addition, the organic mol-ecules are associated by ?-? stacking inter-actions between symmetry-equivalent anti-parallel non-nitro-gen aromatic rings, with inter-planar distances of 3.543?(2)?Å.

Bis(?-4-nitro-phthalato)bis-[diaqua-(1,10-phenanthroline)manganese(II)].

Project description:In the title compound, [Mn(2)(C(8)H(3)NO(6))(2)(C(12)H(8)N(2))(2)(H(2)O)(4)], the Mn(II) atom in the centrosymmetric binuclear unit has a distorted octa-hedral geometry and is coordinated by a chelating 1,10-phenanthroline ligand, two monodentate carboxyl-ate anions from two 4-nitro-phthalates and two coordinated water mol-ecules. The two Mn(II) ions in the mol-ecule are bridged by two 4-nitro-phthalate anions, both in a bis-monodentate mode, which finally leads to the formation of the binuclear unit. Intra-molecular O-H?O hydrogen bonds between the coordinated and uncoordinated O atoms of one monodentate carboxyl-ate group and the corresponding coordinated water mol-ecules result in an eight-membered and two six-membered rings. In the crystal structure, inter-molecular O-H?O hydrogen bonds link the dinuclear mol-ecules into supra-molecular chains propagating parallel to [100].

trans-Bis(nitrato-?O)bis-(1,10-phenanthroline-?(2)N,N')manganese(II).

Project description:In the title compound, [Mn(NO(3))(2)(C(12)H(8)N(2))(2)], the Mn(II) atom lies on a twofold rotation axis, and is six-coordinated in a distorted trans-N(4)O(2) octa-hedral environment by four N atoms from two 1,10-phenanthroline ligands and two O atoms from two nitrate anions. The nitrate anion is disordered about a twofold rotation axis with fixed occupancy factors of 0.5. In the crystal, mol-ecules are linked by weak C-H?O hydrogen bonds and ?-? stacking inter-actions [centroid-centroid distance = 4.088?(5)?Å] into a three-dimensional supra-molecular network.

Project description:In the crystal structure of the title compound, [Mn(NO(3))(2)(C(12)H(8)N(2))](n), the Mn(II) atoms are linked by nitrate ligands to form a chain. Each Mn(II) atom is five-coordinated by two N atoms of a 1,10-phenanthroline ligand and three O atoms of two nitrates within a trigonal-bipyramidal coordination geometry. In the crystal structure, the chains are linked by hydrogen bonds into a polymeric ribbon structure.

catena-Poly[[bis-(?(3)-5-hy-droxy-isophthalato)bis-(pyrazino-[2,3-f][1,10]phenanthroline)dicadmium] dihydrate].

Project description:The title coordination polymer, {[Cd(2)(C(8)H(4)O(5))(2)(C(14)H(8)N(4))(2)]·2H(2)O}(n), has a layered structure. The asymmetric unit contains two Cd(II) ions, two pyrazino-[2,3-f][1,10]phenanthroline, two 5-hy-droxy-isophthalate (hip) ligands and two lattice water mol-ecules. Each Cd(II) ion is coordinated by two N atoms from a chelating pyrazino-[2,3-f][1,10]phenanthroline and four O atoms from three different hip ligands, resulting in a distorted CdN(2)O(4) octa-hedral coordination environment. The hip ligand connects adjacent Cd(II) ions, forming forming layers parallel to (010). Intralayer O-H?O hydrogen bonds involving the hydroxy groups and solvent water molecules consolidate the crystal packing.

Bis(2,9-dimethyl-1,10-phenanthroline-κN,N')bis-(nitrato-κO,O')lead(II).

Project description:In the title complex, [Pb(NO(3))(2)(C(14)H(12)N(2))(2)], the lead ion is chelated by two 2,9-dimethyl-1,10-phenanthroline (dmphen) ligands and two nitrate anions in a slightly distorted square-anti-prismatic geometry. Intra- and inter-molecular π-π stacking is present in the crystal structure, and the centroid-centroid distances between the benzene and pyridine rings of adjacent dmphen ligands are 3.492 (3) and 3.592 (3) Å, respectively. Inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions help to stabilize the crystal structure.

Diaqua-bis-(1,10-phenanthroline-?N,N')cadmium sulfate hexa-hydrate.

Project description:The title compound, [Cd(C(12)H(8)N(2))(2)(H(2)O)(2)]SO(4)·6H(2)O, was obtained unexpectedly during an attempt to synthesize a cadmium complex with bidentate bridging sulfate ligands via hydro-thermal synthesis. The Cd(II) metal ion is six-coordinated by two chelating 1,10-phenanthroline ligands and two water mol-ecules, resulting in a distorted octa-hedral geometry for the metal ion. The two chelating N(2)C(2) groups are almost perpendicular to each other [dihedral angle = 86.75?(2)°]. In the crystal, the [Cd(C(12)H(8)N(2))(2)(H(2)O)(2)](2+) complex cations join with the sulfate anions through two O(water)-H?O(sulfate) hydrogen bonds. These ion pairs are further inter-linked into a two-dimensional supermolecular structure via additional O-H?O hydrogen bonds.

Tris(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')holmium(III).

Project description:In the title compound, [Ho(NO(3))(3)(C(12)H(8)N(2))(2)], the ten-coordinate Ho(III) ion is chelated by four N atoms from two phenanthroline (phen) ligands and six O atoms from three bidentate nitrate groups. The environment around the Ho atom can be described as a distorted bicapped square anti-prism. Two phenanthroline ligands form a dihedral angle of 43.72 (13)°. Short inter-molecular distances between the centroids of the six-membered rings [3.6887 (14)-3.8374 (16) Å] indicate the existence of π-π inter-actions, which link the mol-ecules into stacks extended in the [10] direction. The crystal packing is further stabilized by weak inter-molecular C-H⋯O hydrogen bonds.

Diaqua-bis(1,10-phenanthroline)magnesium dichromate(VI) 1,10-phenanthroline disolvate.

Project description:In the title compound, [Mg(C(12)H(8)N(2))(2)(H(2)O)(2)][Cr(2)O(7)]·2C(12)H(8)N(2), the cation and anion are situated on a twofold rotation axis. The Mg(II) ion is coordinated by four N atoms from two 1,10-phenanthroline ligands and two O atoms from coordinated water mol-ecules in a distorted octa-hedral geometry. Inter-molecular O-H?N and O-H?O hydrogen bonds and ?-? inter-actions between the aromatic rings [shortest centroid-centroid separation = 3.527?(2)?Å] link the cations, anions and 1,10-phenanthroline solvent mol-ecules into a hydrogen-bonded cluster.

Project description:The title complex, [Pr(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))]·2C(12)H(8)N(2), has a polymeric chain structure, with two uncoordinated 1,10-phenanthroline mol-ecules in the lattice. The Pr(III) centre has a monocapped square-anti-prismatic coordination geometry, comprised of two N atoms from one chelating 1,10-phenanthroline ligand, four carboxyl-ate O atoms from four 4-hy-droxy-benzoate anions and three O atoms from two nitrate anions. The 4-hy-droxy-benzoate and nitrate anions function as ?(2)-bridging ligands and link the Pr(III) ions into a one-dimensional chain structure along the c axis. Inter-molecular O-H?N hydrogen bonds are observed between the 4-hy-droxy-benzoate anions and the uncoordinated 1,10-phenanthroline mol-ecules.
