Catena-Poly[[(1,10-phenanthroline-?N,N')lead(II)]-?-azido-?N:N-?-nitrito-?O,O':O'-[(1,10-phenanthroline-?N,N')lead(II)]-di-?-azido-?N:N].

ABSTRACT: The title coordination polymer, [Pb(2)(N(3))(3)(NO(2))(C(12)H(8)N(2))(2)](n), has as the repeat unit a centrosymmetric dinuclear mol-ecule having azide and nitrite groups that bridge adjacent heterocycle-coordinated metal centers. One of the azide group uses its terminal ends to bridge whereas the nitrite group chelates to one metal atom and uses one of its O atoms to bridge. The azide and nitrite groups are disordered with respect to each other in a 1:1 ratio. Adjacent dinuclear mol-ecules are further bridged by the other two azide groups, generating a linear chain motif parallel to [010]. Half of the Pb atoms show a ?-dodeca-hedral coordination and the other half show a ?-penta-gonal-bipyramidal coordination.

catena-Poly[[(1,10-phenanthroline)cobalt(II)]-di-?-azido].

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 ?(1,1) and ?(1,3) modes. The ?(1,3) bridging mode gives rise to an infinite one-dimensional chain along the a axis, whereas the ?(1,1) bridging mode is responsible for the formation of the binuclear Co(II) complex.

catena-Poly[di-?(1,1)-azido-(1,10-phenanthroline)cadmium(II)].

Project description:The asymmetric unit of the title Cd(II) compound, [Cd(N(3))(2)(C(12)H(8)N(2))](n), contains a Cd(II) atom, located on a twofold axis passing through the middle of the phenanthroline mol-ecule, one azide ion and half of a 1,10-phenanthroline mol-ecule. The Cd(II) atom exhibits a distorted octa-hedral coordin-ation including one chelating 1,10-phenanthroline ligand and four azide ligands. The crystal structure features chains along the c direction in which azide groups doubly bridge two adjacent Cd(II) atoms in an end-on (EO) mode. Inter-chain ?-? stacking inter-actions, with centroid-centroid separations of 3.408?(2)?Å between the central aromatic rings of 1,10-phenanthroline mol-ecules, lead to a supra-molecular sheet parallel to the bc plane.

Project description:In the title compound, [PbBr(2)(C(14)H(12)N(2))](n), the Pb(II) atom lies on a twofold rotation axis. The N-heterocycle-chelated Pb(II) atom exists in a distorted octa-hedral geometry owing to two long Pb?Br inter-actions [2.9562?(5) and 3.2594?(5)?Å]. These result in a zigzag chain running along the c axis. The lone pair is stereochemically inactive.

Project description:In the title coordination polymer, [Cu(C(2)O(4))(C(12)H(8)N(2))](n), the Cu(II) atom is six-coordinated by four O atoms from two oxalate ligands and two N atoms from one 1,10-phenanthroline (phen) ligand in a distorted octa-hedral coordination geometry. The oxalate anions act as bis-bidentate ligands, bridging the Cu-phen units in zigzag chains extending parallel to [100]. Inter-chain C-H?O hydrogen bonding and ?-? stacking inter-actions [centroid-centroid distance = 3.7439?(17)?Å] assemble neighboring chains, forming a three-dimensional supra-molecular network.

catena-Poly[[(1,10-phenanthroline)lead(II)]bis-(?-5-chloro-2-hy-droxy-benzoato)].

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[[aqua-(1,10-phenanthroline)cadmium(II)]-μ-benzene-1,4-di-carboxyl-ato].

Project description:The title compound, [Cd(C(8)H(4)O(4))(C(12)H(8)N(2))(H(2)O)](n), is a new coordination polymer of benzene-1,4-dicarboxyl-ate with cadmium(II) and 1,10-phenanthroline. The Cd(II) ion is coordinated by two N atoms from the 1,10-phenanthroline mol-ecule, three O atoms from two crystallographically independent benzene-1,4-dicarboxyl-ate ligands and the O atom of a coordinated water mol-ecule, forming a heavily distorted octa-hedron. The 1,10-phenanthroline ligand is approximately planar within 0.073 (4) Å. The two different benzene-1,4-dicarboxyl-ate ligands each coordinate to two Cd(II) ions in bidentate and monodentate modes, forming an infinite zigzag chain. Adjacent chains are packed tightly by strong π-π inter-actions [centroid-centroid distances = 3.851 (2) and 3.859 (2) Å] between the aromatic rings of the benzene-1,4-dicarboxyl-ate ligand and the 1,10-phenanthroline of a neighboring chain, forming a sheet parallel to (011). Different sheets are linked together via O-H⋯O hydrogen bonds between the coordinated water mol-ecules and the O atoms of the carboxyl-ate groups, forming a three-dimensional network.

catena-Poly[[bis-(μ-3-carboxy-benzoato)bis-(1,10-phenanthroline)tricopper(II)]-di-μ(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 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 Pb(II) complex, [Pb(2)(C(2)Cl(3)O(2))(2)(NO(3))(2)(C(12)H(8)N(2))(2)](n), the 1,10-phenanthroline ligand is chelating, the nitrate anion chelates one Pb(II) ion and simultaneously bridges a neighbouring Pb(II) ion via the third O atom, and the trichloro-acetate anion is bidentate, bridging two Pb(II) ions. The coordination geometry is based on a penta-gonal-bipramidal geometry defined by an N(2)O(5) donor set with no obvious stereochemical role for the lead-bound lone pair of electrons. The coordination polymer has a zigzag topology along [010] and comprises alternating eight-membered {PbONO}(2) and {PbOCO}(2) rings.

Project description:In the title coupound, [Mn(C(9)H(6)O(4))(C(12)H(8)N(2))](n), the Mn(II) ion is coordinated by two N atoms [Mn-N = 2.273 (3) and 2.305 (2) Å] from a 1,10-phenanthroline ligand and four O atoms [Mn-O = 2.112 (2)-2.343 (3) Å] from three 5-methyl-isophthalate (mip) ligands in a distorted octa-hedral geometry. 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.

catena-Poly[bis(dimethylazanium) [[chloridocopper(II)]-di-?-chlorido-[chloridocopper(II)]-di-?-azido-?N:N]].

Project description:The crystal structure of the title complex, {(C(2)H(8)N)[CuCl(2)(N(3))]}(n), exhibits inorganic chains consisting of Cu(II) cations as well azide and chloride anions. The chains, made up from Cu-Cl-Cu-N-Cu linkages, are aligned parallel to the c axis. This architecture is further stabilized by a number of N-H?Cl hydrogen bonds involving the protonated charge-compensating dimethyl-amine cations and chloride atoms.
