Catena-Poly[[(1,10-phenanthroline-κ² N,N')lanthanum(III)]-μ-(5-bromo-2-hy-droxy-benzoato)-κ² O¹:O¹'-di-μ-chlorido].

ABSTRACT: 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. 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. π-π 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 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 polymeric structure is built up from bridging carboxyl-ate O atoms, forming chains along [100]. The crystal structure is stabilized by π-π 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.

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 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.

catena-Poly[[bis-[aqua-(1,10-phenanthroline)lead(II)]-bis-(μ₃-2-hy-droxy-5-sulfonato-benzoato)] acetic acid monosolvate].

Project description:In the title compound, [Pb₂(C₇H₄O₆S)₂(C₁₂H₈N₂)₂(H₂O)₂]·CH₃COOH, 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 π-π 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.

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.

Project description:In the title compound, [Co(C(14)H(8)O(5))(C(12)H(8)N(2))](n), the Co(II) atom is six-coordinated in a distorted octa-hedral coordination geometry by four O atoms from two chelating carboxyl-ate groups from different 2,4'-oxydibenzoate anions and by two N atoms from a 1,10-phenanthroline (phen) ligand. The two benzene rings of the 2,4'-oxydibenzoate ligand form a dihedral angle of 77.14 (16)°. Adjacent Co(II) atoms are bridged by 2,4'-oxydibenzoate anions to form a helical chain that propagates along the b-axis direction. Neighboring chains are further assembled by inter-molecular π-π stacking inter-actions between inversion-related phen ligands [centroid-to-centroid distance = 4.0869 (8) Å] to form a two-dimensional supra-molecular architecture.

Project description:In the title compound, [La(C(7)H(5)O(4))(3)(C(12)H(8)N(2))(3)(H(2)O)(2)]·C(12)H(8)N(2), the La(III) atom is coordinated by four N atoms from two chelating 1,10-phenanthroline (phen) ligands, four O atoms from three 2,6-dihy-droxy-benzoate (DHB) anions (one monodentate, the other bidentate) and two water O atoms, completing a distorted LaN(4)O(6) bicapped square-anti-prismatic geometry. Within the mononuclear complex mol-ecule, intra-molecular π-π stacking inter-actions are observed, the first between a coordinated phen mol-ecule and a DHB ligand [centroid-centroid distance = 3.7291 (16) Å], and the second between a coordinated phen mol-ecule and an uncoordinated phen ligand [centroid-centroid distance = 3.933 (2) Å]. Inter-molecular π-π stacking is observed between adjacent complexes [inter-planar distance = 3.461 (3) Å]. Intra- and inter-molecular O-H⋯O hydrogen bonds are observed in the DHB ligands and between a water mol-ecule and DHB ligands, respectively. O-H⋯N hydrogen bonds are also observed in the DHB ligands and between uncoordinated phen mol-ecules and aqua ligands.
