Catena-Poly[[[(1,10-phenanthroline-κ(2)N,N')praseodymium(III)]-di-μ-4-hydroxy-benzoato-κ(4)O(1):O(1')-μ-nitrato-κ(3)O,O':O] bis-(1,10-phenanthroline)].

ABSTRACT: 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 μ(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.

Project description:In the title complex, [La(C₇H₄BrO₃)Cl₂(C₁₂H₈N₂)](n), the La(III) ion is eight-coordinated by two carboxyl-ate O atoms from two 5-bromo-salicylate ligands, two N atoms from a chelating 1,10-phenanthroline ligand and four bridging Cl atoms in a distorted square-anti-prismatic geometry.

Project description:The title complex, [Pr(2)(C(8)H(7)O(3))(6)(C(12)H(8)N(2))(2)](n), which has an inversion centre midway between the two Pr(III) atoms of the structural unit, forms a one-dimensional polymer bridged alternately by either two bidentate, or two bidentate and two terdentate, phenoxy-acetate carboxyl-ate groups. Each Pr(III) atom is thus nine-coordinated by two N atoms of a 1,10-phenanthroline ligand and seven O atoms from six phenoxy-acetate ligands. The coordination geometry at the Pr(III) atom is distorted tricapped trigonal prismatic. One phenyl ring is disordered over two positions; the site occupancy factors are ca 0.6 and 0.4.

Project description:The title copper coordination polymer, [Cu(3)(C(8)H(4)O(4))(2)(C(8)H(5)O(4))(2)(C(10)H(8)N(2))(2)](n), was synthesized by reacting Cu(NO(3))(2), isophthalic acid and 1,10-phenanthroline under hydro-thermal conditions. The trinuclear unit presents a central almost planar CuO(4) chromophore with the cation on a symmetry center, and two symmetry-related CuN(2)O(3) groups with the metal centre in a distorted square-pyramidal environment. These units are bridged by isophthalate ligands into one-dimensional double-chain coordination polymers which are, in turn, connected by various π-π stacking inter-actions (face-to-face distance ca 3.45 Å) and O-H⋯O hydrogen bonds, forming a three-dimensional supra-molecular network.

Di-μ-benzoato-κ(3)O,O':O;κ(3)O:O,O'-bis-[aqua-(nitrato-κO)(1,10-phenanthroline-κ(2)N,N')lead(II)].

Project description:The title compound, [Pb(2)(C(7)H(5)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)(H(2)O)(2)], crystallizes as a dinuclear centrosymmetric dimer containing two Pb(II) atoms bridged by two benzoate ligands. Each Pb(II) atom is seven-coordinated by a water mol-ecule, a nitrate anion, a 1,10-phenanthroline (phen) ligand and two benzoate anions. The crystal packing is stabilized by O-H⋯O hydrogen bonds and by π-π stacking between neighboring phen ligands, with a centroid-centroid distance of 3.557 (3) Å.

Project description:In the crystal structure of the binuclear title complex, [Co(N(3))(2)(C(12)H(8)N(2))](n), each Co(II) cation is coordinated by two N atoms from one chelating 1,10-phenanthroline ligand and four azide ligands in a slightly distorted octa-hedral coordination. The two Co(II) cations of the binuclear complex are related by an inversion centre and are bridged by two symmetry-related azide ligands in both μ(1,1) and μ(1,3) modes. The μ(1,3) bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the μ(1,1) bridging mode is responsible for the formation of the binuclear Co(II) complex.

Bis(2,6-dihy-droxy-benzoato-κO,O)(nitrato-κO,O')bis-(1,10-phenanthroline-κN,N')praseodymium(III).

Project description:The mononuclear title complex, [Pr(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(2)], is isostructural with related complexes of other lanthanides. The Pr(III) atom is in a pseudo-bicapped square-anti-prismatic geometry, formed by four N atoms from two chelating 1,10-phenanthroline (phen) ligands and six O atoms, four from two 2,6-dihy-droxy-benzoate (DHB) ligands and the other two from nitrate anions. π-π stacking inter-actions between the phen and DHB ligands [centroid-centroid distances = 3.518 (2) and 3.778 (2) Å] and the phen and phen ligands [face-to-face separation = 3.427 (6) Å] of adjacent complexes stabilize the crystal structure. Intra-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands.

Project description:In the title compound, [Cu(C(7)H(5)O(3))(NO(3))(C(14)H(12)N(2))], the Cu(II) ion is five-coordinated in a slightly distorted square-pyramidal geometry by one O atom of a nitrate anion, two O atoms of a 4-hydroxy-benzoate anion, and two N atoms from a bidentate 2,9-dimethyl-1,10-phenanthroline (dmphen) ligand. In the crystal structure, inversion-related mol-ecules are linked into dimers by O-H⋯O hydrogen bonds. The packing is further stabilized by π-π inter-actions involving the benzene rings of the dmphen and hydroxy-benzoate units, with centroid-centroid distances of 3.4930 (14) or 3.5727 (14) Å.

catena-[[(nitrato-κO)silver(I)]-μ-1,10-phenanthroline-5,6-dione-κO,O':N,N'].

Project description:In the title one-dimensional coordination polymer, [Ag(NO(3))(C(12)H(6)N(2)O(2))](n), the Ag(I) atom is penta-coordinated by two N atoms from a 1,10-phenanthroline-5,6-dione (phen-dione) ligand, one O atom from the nitrate anion and two O atoms from another phen-dione ligand. The coordination environment around silver is slightly distorted square-pyramidal. Inter-estingly, the Ag-O distances to the phen-dione ligand are different [Ag-O = 2.612 (6) and 2.470 (5) Å]. The one-dimensional chains run parallel to [101] and are further inter-connected by weak hydrogen bonds (C-H⋯O) and π-π stacking inter-actions [centroid-centroid distances 3.950 (4) and 3.792 (4) Å], forming a three-dimensional supra-molecular network.

Poly[diaqua-bis-(nitrato-κ²O,O')bis-(1,10-phenanthroline-κ²N,N')-μ₃-succinato-dicadmium].

Project description:In the title coordination polymer, [Cd₂(C₄H₄O₄)(NO₃)₂(C₁₂H₈N₂)₂(H₂O)₂](n), the Cd(II) ion is seven-coordinated within a distorted penta-gonal-bipyramidal O₅N₂ 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. π-π stacking inter-actions with a minimum plane-to-plane separation of 3.462 (2) Å occur between phenanthroline ligands.
