Poly[(mu2-1,3-di-4-pyridylpropane-kappa2N:N')(mu3-glutarato-kappa3O:O':O'')dizinc(II)].

The title compound, [Zn2(C5H6O4)2(C13H14N2)]n or [Zn2(glu)2(bpp)]n, is a novel zinc polymer based on mixed flexible glutarate (glu) and 1,3-di-4-pyridylpropane (bpp) ligands. The Zn(II) center has a distorted tetrahedral geometry and the central atom of the bpp ligand is located at a special site with a C2 axis passing through it. A layer is formed by Zn-glu bonding. Such layers are pillared by bpp ligands, forming a three-dimensional framework with large channels. The inverted interpenetration of two three-dimensional frameworks completes the molecular structure.

catena-Poly[[tetraaquamanganese(II)]-mu-4-(carboxylatomethylsulfanyl)phenoxyacetato].

The title compound, [Mn(C10H8O5S)(H2O)4]n, a one-dimensional manganese(II) complex comprising helical chains bridged by 4-(carboxylatomethylsulfanyl)phenoxyacetate ligands has been characterized by single-crystal X-ray diffraction analysis. Hydrogen-bonding interactions between adjacent chains extend the complex into a three-dimensional supramolecular architecture.

A 3-D noninterpenetrating diamondoid network of a decanuclear copper(I) complex.

The solvothermal reaction of CuCl(2).2H(2)O with pyridine-4-thiol and ethanol yielded a novel photoluminescent 3-D polymeric complex with an interesting decorated diamondoid network that is constructed of decanuclear copper(I) cluster units and mu(4)-Cl ligands. The in situ generation of CuSO(4).5H(2)O implies the spontaneous occurrence of desulfurization and redox reactions in the present system.

Poly[aquaneodymium(III)-mu5-2-oxido-5-sulfonatobenzoato].

The title compound, [Nd(C(7)H(3)O(6)S)(H(2)O)](n) or [Nd(SSA)(H(2)O)](n) (H(3)SSA is 5-sulfosalicylic acid), was synthesized by the hydrothermal reaction of Nd(2)O(3) with H(3)SSA in water. The compound forms a three-dimensional network in which the asymmetric unit contains one Nd(III) atom, one SSA ligand and one coordinated water molecule. The central Nd(III) ion is eight-coordinate, bonded to seven O atoms from five different SSA ligands [Nd-O = 2.405 (4)-2.612 (4) angstroms] and one aqua O atom [Nd-OW = 2.441 (4) angstroms].

4,4'-Thiodipyridinium tetrachlorocopper(II).

The title compound, (C(10)H(10)N(2)S)[CuCl(4)], was obtained by the reaction of cupric chloride with pyridine-4-thiol in a mixture of acetonitrile and tetrahydrofuran, suggesting that the desulfurization and coupling reactions of pyridine-4-thiol occurred in the presence of the Cu(2+) ion. X-ray diffraction analysis reveals the presence of one 4,4'-thiodipyridinium cation, H(2)bps(2+), and one [CuCl(4)](2-) anion. The cations interact with the anions via N-H...Cl hydrogen-bonding interactions to form a closed 'chair' conformation.

Interweaving 3D network with double helical tubes filled by 1D coordination polymer chains.

The hydrothermal reaction of mellitic acid, 4,4'-bipydine, and Cu(CH(3)COO)(2).H(2)O gave rise to a novel 3D supramolecular architecture interpenetrated by three types of coordination polymer motifs. Two independent [[Cu(2)(mellitate)(4,4'-bpy)(H(2)O)(2)](2)(-)] 3D polymers incorporating helical substructures were interwoven into a 3D network with double-stranded helical tubes that host 1D linear polymers [Cu(4,4'-bpy)(H(2)O)(4)](2+)](n).

Poly[[[(1,10-phenanthroline-kappa2N,N')zinc(II)]-mu3-5-hydroxyisophthalato-kappa4O,O':O":O"'] monohydrate].

In the title compound, [[Zn(C8H4O5)(C12H8N2)].H2O]n or [[Zn(OH-BDC)(phen)].H2O]n (where OH-H2BDC is 5-hydroxyisophthalic acid and phen is 1,10-phenanthroline), the Zn atoms are coordinated by two N atoms from the phen ligands and by four O atoms from hydroxyisophthalate ligands in a highly distorted octahedral geometry, with Zn-O distances in the range 2.042 (4)-2.085 (5) A and Zn-N distances of 2.133 (5) and 2.137 (5) A. The [[Zn(OH-BDC)(phen)].H2O]n infinite zigzag polymer forms a helical chain of [Zn2(OH-BDC)2]n units. Face-to-face pi-pi interactions (3.60-3.75 A) occur between two phen rings belonging to the same helical chain. Consolidation of the packing structure is achieved by O-H...O hydrogen-bonding interactions between the carboxylate O atoms, the hydroxyl group and the water molecule, forming two-dimensional sheets.

Poly[[diaquatris(mu6-benzene-1,2,4,5-tetracarboxylato)tris(mu2-4,4'-bipyridine)hexacopper(II)] dihydrate].

The hydrothermal reaction of an aqueous solution of Cu(CH(3)COO)(2).H(2)O, 1,2,4,5-benzenetetracarboxylic acid and 4,4'-bipyridine gave rise to the interesting title three-dimensional polymer [[Cu(6)(btec)(3)(4,4'-bpy)(3)(H(2)O)(2)].2H(2)O](n) (btec is 1,2,4,5-benzenetetracarboxylate, C(10)H(2)O(8)(4-), and 4,4'-bpy is 4,4'-bipyridine, C(10)H(8)N(2)), in which each btec ligand links six copper(II) cations into a lamellar [Cu(6)(btec)(3)(H(2)O)(2)](n) subpolymer framework. There are two distinct diamine units and two distinct carboxylate units, with one of each lying across an inversion centre.

Tetrakis(pyridinium-2-thiolato)zinc(II) dinitrate.

The crystal structure of the title compound, [Zn(C(5)H(5)NS)(4)](NO(3))(2), consists of a [Zn(C(5)H(5)NS)(4)](2+) (C(5)H(5)NS is pyridinium-2-thiolate) cation and two nitrate anions. The central Zn(II) atom lies at a site with imposed -4 symmetry and is surrounded by four S atoms [Zn-S = 2.3371 (5) A] from four symmetrical pyridinium-2-thiolate ligands in a distorted tetrahedral geometry. There are N-H.O hydrogen-bonding interactions between the pyridinium-2-thiolate ligands and nitrate O atoms. In addition, pi-pi interactions via aromatic N-containing ligands are discussed.

A novel ligand-unsupported 3D framework polymer of trimeric copper(I) and its NLO property.

A novel 3-D coordination polymer with trimeric copper (I) unit, [Cu(3)(CN)(IN)(2)](n)(IN = isonicotinate), was hydrothermally synthesized by the reaction of Cu(NO(3))(2).3H(2)O with isonicotinic and terephthalic acids. The structure was characterized to be a twofold interpenetrated 3-D coordination network polymer with two-coordinated copper(I). It has a powder SHG efficiency about that of KDP.
