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

ABSTRACT: 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.

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-[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.

Each mip dianion acts as a tetra-dentate ligand connecting three Mn ions. The crystal packing exhibits π-π inter-actions [3.599 (2)-3.755 (2) Å] between the centroids of the six-membered rings of neighbouring 1,10-phenanthroline ligands.

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 ?-? stacking inter-actions between inversion-related phen ligands [centroid-to-centroid distance = 4.0869?(8)?Å] to form a two-dimensional supra-molecular architecture.
