Poly[(1,10-phenanthroline-κ2N,N′)lead(II) μ4-(4-sulfonatobenzoato-κ4O,O′:O′′,O′′′ hydrate]

In the title polymeric compound, [Pb(C12H8N2)(C7H4O5S)]n·nH2O, the seven-coordinate PbII atom is surrounded by one 1,10-phenanthroline (phen) and four 4-sulfonatobenzoate (sb) ligands in a hemidirected coordination geometry. Both the sulfonyl and carboxy groups of the sb ligand bridge the neighboring PbII atoms to form a two-dimensional sheet structure.

Different supramolecular assemblies in two 1:1 proton-transfer compounds of sulfobenzoic acids with aromatic amines.

Two 1:1 proton-transfer complexes of sulfobenzoic acids with aromatic amines, namely 4-[2-(4-pyridyl)ethenyl]pyridinium 2-carboxybenzenesulfonate, C(12)H(11)N(2)(+).C(7)H(5)O(5)S(-), (I), and 1,10-phenanthrolin-1-ium 4-carboxybenzenesulfonate dihydrate, C(12)H(9)N(2)(+).C(7)H(5)O(5)S(-).2H(2)O, (II), have very different hydrogen-bonding patterns compared with reported organic sulfobenzoic acid complexes. In (I), two cations and two anions form a four-molecule loop, in which pi-pi interactions occur. In (II), the anions and water molecules form a three-dimensional hydrogen-bonding network, while the cations only act as pendant components. The water molecules play a central role in the formation of the abundant hydrogen-bonding architecture in (II). The relative poorness and richness of hydrogen bonds in (I) and (II), respectively, give rise to novel hydrogen-bonding patterns.

catena-Poly­[[[di-μ-chloro-bis­[(5-nitro-­1,10-phenanthroline)copper(II)]]-μ-terephthalato] bis(N,N′-di­methyl­form­amide)]

In the structure of the title complex, {[Cu2Cl2(C8H4O4)(C12H7N3O2)2]·2C3H7NO}n, each copper cation is surrounded by one O atom from a terephthalate (ta) ligand, two bridging Cl atoms, and two N atoms from a 5-nitro-1,10-phenanthroline ligand. Dimeric blocks of [Cu2(C12H7N3O2)2(ta)] are held together by two μ-chloro bridges, which create a one-dimensional architecture. There is a center of symmetry halfway between the two Cu atoms and the two Cl atoms and at the center of the phenyl ring of the ta group.

Poly[zinc(II)‐μ2‐4,4′‐bipyridine‐di‐μ2‐formato]: a chiral three‐dimensional coordination polymer

The title compound, [Zn(CHO2)2(C10H8N2)]n, is a chiral three-dimensional coordination polymer. The Zn atom, the two bipyridine N atoms, and the bridging bipyridine C atoms occupy special positions with site symmetry 2. In the extended structure, both the ligands act as linkers in μ2-mode. The compound is isostructural with its copper analogue.

A one-dimensional mixed-anion lead(II) coordination polymer: catena-poly[[(1,10-phenanthroline)lead(II)]-μ-benzoato-μ-nitrato-[(1,10-phenanthroline)lead(II)]-di-μ-benzoato]

In the title polymeric compound, [Pb2(C7H5O2)3(NO3)(C12H8N2)2]n, both independent Pb atoms adopt an eight-coordinate geometry formed by one nitrate, three benzoate and one 1,10-phenanthroline ligand. The one-dimensional polymer consists of dimeric [Pb2(C7H5O2)3(NO3)(C12H8N2)2] units, in which all nitrate and benzoate ligands act in a bridging-chelating coordination mode.

Poly[aqua­(2,2′‐bipyridine)(μ3‐3‐sulfonatobenzoato)lead(II)]

In the title polymeric complex, [Pb(C7H4O5S)(C10H8N2)(H2O)]n, each PbII atom has a seven-coordinate geometry. The 3-sulfonatobenzoate ligand acts as a μ3-bridging linker, generating a one-dimensional ladder. The packing is further stabilized by an O—H⋯O hydrogen-bonding network.

A mixed-valence CuII/CuI anion–cation complex: bis­[μ-5-sulfosali­cylato(3–)]bis­[(di-2-pyridylamine)­copper(II)] bis­[bis­(di-2-pyridyl­amine)copper(I)] dihydrate

The title compound, [CuII(2)(C7H3O6S)2(C10H9N3)2][CuI(C10H9N3)2]2.2H2O, consists of anionic CuII moieties, cationic CuI species and uncoordinated water molecules. The anionic dimeric unit consists of one crystallographically independent fully deprotonated 5-sulfosalicylate (2-oxido-5-sulfonatobenzoate) anion, a di-2-pyridylamine group and a CuII atom. Each CuII atom is five-coordinate within a square-pyramidal geometry. The anion lies on a special position of -1 site symmetry. In the cationic monomer, the CuI atom adopts tetrahedral geometry. The cations and anions are connected by O-H...O and N-H...O hydrogen bonds.

catena‐Poly[[[cis‐diaqua­(2,2′‐bipyridine)cadmium(II)]‐μ‐3‐sulfonatobenzoato] monohydrate]

# 2006 International Union of Crystallography All rights reserved The title complex, {[Cd(C7H4O5S)(C10H8N2)(H2O)2] H2O}n, which was obtained by hydrothermal synthesis, forms a onedimensional zigzag chain. The coordination polyhedron of the Cd atom is a distorted octahedron completed by four O atoms from two water molecules and two 3-sulfonatobenzoate ligands, and two N atoms from 2,20-bipyridine. O—H O hydrogen bonds give rise to a three-dimensional network.

Aqua­bis(1,10‐phenanthroline)(3‐sulfonatobenzoato)cadmium(II) tetra­hydrate

In the title mononuclear complex, [Cd(C7H4O5S)(C12H8N2)2(H2O)]·4H2O, the CdII atom is coordinated in a capped trigonal–prismatic geometry by four N atoms and three O atoms. The 3-sulfonatobenzoate ligand chelates the CdII atom only via the carboxyl group. In the crystal structure, extensive O—H⋯O hydrogen bonds generate a three-dimensional network.

Poly[[tris(di-2-pyridylamine)tris(μ-5-sulfonatosalicylato)tricopper(II)] trihydrate]

In the title compound, [Cu3(C10H9N3)3(C7H3O6S)2]·3H2O, [Cu3(ssal)2(dpa)3] units (dpa is 2,2′-dipyridylamine and ssal is 5-sulfonatosalicylate) are found, which consist of one crystallographically independent ssal anion, and two each of crystallographically independent dpa ligands and Cu atoms, the unit lying on a twofold rotation axis. One Cu atom is four-coordinated by one dpa ligand and one ssal anion within a square-planar geometry, whereas the second Cu atom is coordinated by one dpa ligand and two ssal anions which are related by symmetry. The first Cu atom has one longer contact to one O atom of a symmetry-related sulfonate group and is, therefore, five-coordinated within a distorted square-pyramidal coordination. The [Cu3(ssal)2(dpa)3] units are connected via the sulfonate groups into layers which are parallel to the ab plane. These layers are further connected by O—H⋯O and N—H⋯O hydrogen bonding via the water molecules.
