Catena-Poly[[[(1,10-phenanthroline-?(2)N,N')praseodymium(III)]-di-?-4-hydroxy-benzoato-?(4)O(1):O(1')-?-nitrato-?(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 ?(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: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. ?-? 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 polymer, [Pb(C(7)H(4)ClO(3))(2)(C(12)H(8)N(2))](n), the Pb(II) ion displays a distorted pseudo-octa-hedral coordination geometry. The metal center is coordinated by six O atoms from four 5-chloro-salicylate ligands and two N atoms from a chelating phenanthroline ligand. The polymeric structure is built up from bridging carboxyl-ate O atoms, forming chains along [100]. The crystal structure is stabilized by ?-? inter-actions between the 1,10-phenanthroline and 5-chloro-salicylate ligands, the shortest centroid-centroid separation between neighbouring aromatic rings being 3.652?(1)?Å.

catena-Poly[[bis-(?-3-carboxy-benzoato)bis-(1,10-phenanthroline)tricopper(II)]-di-?(3)-isophthalato].

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 ?-? stacking inter-actions (face-to-face distance ca 3.45?Å) and O-H?O hydrogen bonds, forming 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.

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.

catena-Poly[[bis-[aqua-(1,10-phenanthroline)lead(II)]-bis-(??-2-hy-droxy-5-sulfonato-benzoato)] acetic acid monosolvate].

Project description:In the title compound, [Pb?(C?H?O?S)?(C??H?N?)?(H?O)?]·CH?COOH, the seven-coordinate Pb(II) atom is chelated by two N atoms of one 1,10-phenanthroline ligand, four O atoms from three 5-sulfosalicylate dianions and one water O atom. Each dianion serves as a bridging ligand, connecting adjacent Pb(II) atoms into a centrosymmetric polymeric chain extending parallel to [001]. There are ?-? inter-actions between the aromatic systems of neighbouring dianions, with plane-to-plane distances of 3.371?(2)?Å, and between phenanthroline ligands, with a centroid-to-centroid distance of 3.484?(2)?Å. O-H?O hydrogen bonding additionally stabilizes the crystal packing. The acetic acid mol-ecules are incorporated in the voids of this arrangement. They exhibit half-occupancy due to disorder around a centre of inversion.

1,10-Phenanthrolin-1-ium nitrate-aqua-bis-(4-hydroxy-benzoato-?O,O')(nitrato-?O,O')(1,10-phenanthroline-?N,N')erbium(III)-1,10-phenanthroline-water (1/1/0.5/2).

Project description:In the title compound, C(12)H(9)N(2) (+)·NO(3) (-)·[Er(C(7)H(5)O(3))(2)(NO(3))(C(12)H(8)N(2))(H(2)O)]·0.5C(12)H(8)N(2)·2H(2)O, the water-mol-ecule-coordinated Er(III) ion is chelated by one 1,10-phenanthroline (phen) ligand, two 4-hy-droxy-benzoate anions and one nitrate anion in a monocapped square-anti-prismatic coordination geometry. The uncoordinating phen mol-ecule is approximately parallel to the 1,10-phenanthrolin-1-ium (Hphen) anion [dihedral angle = 3.3?(4)°]. The centroid-centroid distance of 3.801?(5)?Å between pyridine rings suggests the existence of ?-? stacking. The crystal structure contains an extensive network of classical O-H?O and N-H?O and weak C-H?O hydrogen bonds. C-H?? inter-actions between phen and 4-hy-droxy-benzoate is also present in the crystal structure. In the crystal, the uncoordinating phen is equally disordered over two sites about an inversion center.

Project description:In the title complex, [La(C?H?BrO?)Cl?(C??H?N?)](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. The La(III) ions are linked by bridging carboxyl-ate groups and chloride anions into a chain along [100]. An intra-molecular O-H?O hydrogen bond is formed in the 5-bromo-salicylate ligand. ?-? inter-actions between the pyridine and benzene rings and between the benzene rings are observed [centroid-centroid distances = 3.794?(5) and 3.804?(4)?Å].

Project description: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.

(2,9-Dimethyl-1,10-phenanthroline-?N,N')(4-hydroxy-benzoato-?O,O')(nitrato-?O)copper(II).

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 ?-? 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.
