Two new two-dimensional coordination polymers, poly[[[aqua( 2,2'-bipyridine-κ² N,N')manganese( II ) ]-µ3-p-phenylenebis(oxyacetato)-κ³O:O':O''] dihydrate], [[Man(C10H8O6)(C10H8N2)(H2O)]·2H2O]n, (I), and poly[[did-mu;-aqua-ibis[aqua sodium(I)]]-mu;4-p-phenylenebis( oxyacetato )-κO: O', O'' : O''',O'''':O'''''], [Na2(C10H8O6)(H2O)4]n, have been synthesized and characterized by X-ray single-crystal diffraction. In (I), there are two 1,4-BDOA2- [p-phenylenebis(oxyacetate) or, more commonly, benzene-1,4-dioxyacetate] ligands, each lying about inversion centres, while in (II), there is one such ligand and it also has crystallographically imposed inversion symmetry. In (I), each MnII atom displays an octahedral MnN2O4 configuration, defined by three carboxyl O atoms of different 1,4-BDOA2- groups, two N atoms of one 2,2'-bipyridine ligand and one water molecule. In (II), each NaI atom is octahedrally coordinated by one ether O atom, two carboxyl O atoms of different 1,4-BDOA2- ligands and three water molecules. The metal ions in complexes (I) and (II) are bridged by 1,4-BDOA2- groups into twodimensional layer structures. Furthermore, three-dimensional supramolecular networks are constructed via hydrogen bonds in (I) and (II), and by additional π-π stacking interactions in (I). [ABSTRACT FROM AUTHOR]

In the title coordination polymer, [Pb(C5H2N2O4)(H2O)] n, the PbII atom is seven-coordinated by one N atom and five O atoms from four individual imidazole-4,5-dicarboxyl­ate (HIDC2−) groups and one water mol­ecule. It is inter­esting to note that the HIDC2− group serves as a bridging ligand to link the PbII atoms into a three-dimensional microporous open-framework. [ABSTRACT FROM AUTHOR]

The crystal structure of the title complex, {[Cu3(C2H3O2)2(OH)2(H2O)4](C10H6O6S2)} n, is built of infinite polymeric cationic {[Cu3(C2H3O2)2(H2O)4(OH)2]2+} n chains stretching along the a axis, with naphthalene-1,5-disulfonate (1,5-nds) anions in between. One independent CuII cation and the 1,5-nds anion occupy special positions on crystallographic inversion centres. Each CuII cation has an octa­hedral coordination environment formed by two carboxyl O atoms, two hydroxo O atoms and two water mol­ecules. The carboxyl­ate and hydroxo groups perform a bridging function, linking adjacent Cu atoms in the chain, with a shortest Cu⋯Cu distance of 2.990 (3) Å. The chains are further linked into a three-dimensional supra­molecular framework via hydrogen-bonding inter­actions involving the sulfonate groups of the 1,5-­nds dianions. [ABSTRACT FROM AUTHOR]

In the title complex, [Mn(C5H4NO)2(C5H5NO)2] n or [Mn(mu;-3-PyO)2(3-PyOH)2] n (3-PyO¯ is the pyridin-3-olate anion and 3-PyOH is pyridin-3-ol), the MnII atom lies on an inversion centre and has octahedral geometry, defined by two N atoms and two deprotonated exocyclic O atoms of symmetry-related pyridin-3-olate ligands [Mn-N = 2.3559 (14) Å and Mn-O = 2.1703 (11) Å], as well as two N atoms of terminal 3-PyOH ligands [Mn-N = 2.3482 (13) Å]. The MnII atoms arc bridged by the deprotonated pyridin-3-olate anion into a layer structure, generating sheets in the (&1macr;01) plane. These sheets are linked by O-H···O hydrogen bonds. There are also π-π and C-H···π interactions in the crystal structure. [ABSTRACT FROM AUTHOR]

The title complex, poly[disilver(I)-µ8-1,5-naphthalenedisulfonato-3,4-η:7,8-η:κ6O:O'O'':O'''O'''':O'''''], [Ag2(C10H6O6S2)]n, exists as a three-dimensional framework of AgI atoms connected by η10,μ8-1,5-naphthalenedisulfonate ligands through both Ag-sulfonate and Ag-η²-arene interactions. Each AgI atom exhibits a distorted tetrahedral geometry defined by three O atoms of independent sulfonate groups and one C=C bond of the naphthalene group. [ABSTRACT FROM AUTHOR]

In the title two-dimensional coordination polymer, [Mn(1,4BDOA)(4,4-bipy)(H2O)2]n [1,4-BDOA2- is the p-phenylenedioxydiacetate dianion (C10H8O6) and 4,4-bipy is 4,4-bipyridine (C10H8N2)], each MnII atom displays octahedral coordination by two O atoms of the 1,4-BDOA2- groups, two N atoms of the 4,4-bipy ligands and two solvent water molecules. The MnII atom, 4,4-bipy ligand and 1,4-BDOA2- group occupy different inversion centres. Adjacent MnII atoms are bridged by 1,4-BDOA2- groups and 4,4-bipy ligands, forming a two-dimensional network with Mn···Mn separations of 11.592 (2) and 11.699 (2) Å. Hydrogen bonds from a water O-H group link the layers in the third dimension. [ABSTRACT FROM AUTHOR]

In the title neutral coordination polymer, [Cd(C6H3ClNO2)2(H2O)2]n, each Cd11 ion is coordinated by one N and four O atoms from three 2-chloronicotinate ligands and by two aqua ligands, defining a distorted monocapped octahedral coordination geometry. Adjacent Cd atoms are linked by the pyridyl N atom and the bidentate carboxylate functional group of a 2-chloronicotinate ligand, forming a one-dimensional infinite chain along the b axis. The Cd···Cd distance is 8.112 (3) Å. These chains are linked by O-H···O and OH···N hydrogen bonds into a three-dimensional network structure. [ABSTRACT FROM AUTHOR]

In the title complex, [Mn(SO4)(C3H7NO)(H2O)2] n, each MnII ion has a distorted octa­hedral geometry formed by three O atoms of three different sulfate groups, one O atom of a dimethyl­formamide ligand and two water mol­ecules. The sulfate groups act as tridentate bridging ligands connecting the MnII ions into a two-dimensional layer structure which can be regraded as a 4.82 network. [ABSTRACT FROM AUTHOR]

In the title three-dimensional coordination polymer, [Sr(4-CPOA)(H2O)] n (where 4-CPOA2− is the 4-carboxylatophenoxy­acetate dianion, C9H6O5), each SrII atom displays a bicapped triangular prismatic configuration, defined by five carboxyl and one ether O atom from five different 4-CPOA2− ligands, as well as two water mol­ecules. The SrII atoms are covalently linked by 4-CPOA2− ligands and water mol­ecules, giving rise to a three-dimensional open framework. In previously studied polymers of this type, the 4-CPOA2− ligand shows a variety of binding modes to metal ions, from mono- to pentadentate. In the present SrII complex, a novel hexadentate bridging mode is observed. [ABSTRACT FROM AUTHOR]

In the title coordination polymer, [Ba(1,3-BDOA)(H2O)2] n (where 1,3-BDOA2− is the m-phenylenedioxydiacetate dianion, C10H8O6), each BaII ion is ten-coordinated by six carboxyl O atoms and two ether O atoms from different 1,3-BDOA2− ligands, as well as by two water mol­ecules, thus defining a dodeca­hedron. The BaII atoms are covalently linked by 1,3-BDOA2− ligands in different crystallographic directions, giving rise to a three-dimensional open framework. The crystal structure is further stabilized by hydrogen bonds and π–π stacking inter­actions. In previously studied polymers of this type, the 1,3-BDOA2− ligand showed multiple bridging modes with metal ions, including bi-, tri-, tetra- and hexa­dentate. The title BaII complex represents a novel three-dimensional coordination polymer constructed by octa­dentate bridging 1,3-BDOA2− ligands. [ABSTRACT FROM AUTHOR]
