Poly[[tris-(?(2)-4,4'-bipyridine N,N'-di-oxide)hexa-nitratodigadolinium(III)] dichloro-methane disolvate].

ABSTRACT: The title one-dimensional coordination network, {[Gd(2)(NO(3))(6)(C(10)H(8)N(2)O(2))(3)]·2CH(2)Cl(2)}(n), is isostructural with the previously reported Tb and Tl coordination networks and to its Eu analog. The Gd(III) cation is coordinated in a distorted tricapped trigonal-prismatic fashion by nine O atoms from three bridging 4,4'-bipyridine N,N'-dioxide ligands and three chelating nitrate anions. None of the atoms lie on a special position, but there is an inversion center located between the rings of one of the ligands. The network topology is ladder-like, and each ladder inter-acts with six neighboring ladders through C-H?O hydrogen bonds. The packing motif of the ladders allows for the formation of channels that run parallel to the a axis; these channels are filled with CH(2)Cl(2) solvent mol-ecules that inter-act with the ladders through C-H?O hydrogen bonds.

catena-Poly[[[tetra-aqua-cobalt(II)]-μ-4,4'-bipyridine-κN:N'] bis-(perchlorate) 4,4'-bipyridine disolvate dihydrate].

Project description:In the title compound, {[Co(C(10)H(8)N(2))(H(2)O)(4)](ClO(4))(2)·2C(10)H(8)N(2)·2H(2)O}(n), slightly distorted octa-hedrally coordinated Co(II) ions situated on inversion centers are linked into polycationic chains through 4,4'-bipyridine tethering ligands. These are connected into supra-molecular layers by hydrogen bonding involving aqua ligands, perchlorate anions and uncoordinated water mol-ecules. A twofold inter-penetrated primitive cubic supra-molecular network is formed by the inter-action of pseudo-layers by hydrogen bonding between aqua ligands and unligated 4,4'-bipyridine mol-ecules.

Poly[diaqua-bis(2,2'-bipyridine)tris-(μ(4)-2,2'-bipyridine-4,4'-dicarboxyl-ato)dineodymium(III)].

Project description:In the crystal structure of the title mixed-ligand coordination polymer, [Nd(2)(C(12)H(6)N(2)O(4))(3)(C(10)H(8)N(2))(2)(H(2)O)(2)](n), the Nd(III) ion is in an octa-hedral coordination environment formed by one water mol-ecule, one chelating 2,2'-bipyridine ligand, and five monodentate carboxyl-ate groups. The local coordination polyhedron around the Nd(III) ion is a bicapped trigonal prism. Two Nd(III) centers are bridged by four carboxyl-ate groups to form an Nd(2) dimeric unit; these are further connected by 2,2'-bipyridine-4,4'-dicarboxyl-ate linkers, resulting in a layered coordination network.

Poly[bis-(4,4'-bipyridine)(μ(3)-4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ato)iron(II)].

Project description:In the polymeric title complex, [Fe(C(16)H(8)O(8))(C(10)H(8)N(2))(2)](n), the iron(II) cation is coordinated by four O atoms from three different 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands and two N atoms from two 4,4'-bipyridine ligands in a distorted octa-hedral geometry. The 4,4'-dicarboxybiphenyl-3,3'-di-carboxyl-ate ligands bridge adjacent cations, forming chains parallel to the c axis. The chains are further connected by inter-molecular O-H⋯N hydrogen bonds, forming two-dimensional supra-molecular layers parallel to (010).

A chiral three-dimensional network in poly[μ-4,4'-bipyridine-di-μ-formato-cadmium(II)].

Project description:In the title compound, [Cd(HCOO)(2)(C(10)H(8)N(2))](n), the Cd(II) ion, located on a position with 2.22 site symmetry, is surrounded by two 4,4'-bipyridine ligands and four formate ligands in a distorted octahedral CdN(2)O(4) coordination. The 4,4'-bipyridine ligands bridge the metal ions, forming one-dimensional chains along different directions, which are further connected by formate ligands into a topologically (10(10).12(4).14)(10)(3) three-dimensional network.

catena-Poly[[tris[silver(I)-μ-4,4'-bi-pyridine-κN:N']] tris-(perchlorate) di-hydrate].

Project description:In the title compound, {[Ag(3)(C(10)H(8)N(2))(3)](ClO(4))(3)·2H(2)O}(n), one of the Ag(I) ions, one of the 4,4'-bipyridine (bipy) ligands and one of the perchlorate anions are each situated on a twofold rotation axis. Each Ag(I) ion is coordinated by two N atoms from two bridging bipy ligands, forming chains along [101]. π-π inter-actions between the pyridine rings [centroid-centroid distances = 3.638 (8) and 3.688 (8) Å] connect the chains. Inter-molecular O-H⋯O hydrogen bonds link the uncoord-inated water mol-ecules and the perchlorate anions.

Poly[(μ-4,4'-bipyridine)(μ-naphthalene-1,4-dicarboxyl-ato)manganese(II)].

Project description:In the crystal structure of the title compound, [Mn(C(12)H(6)O(4))(C(10)H(8)N(2))](n), the Mn atoms are each coordinated by four O atoms of naphthalene-1,4-dicarboxyl-ate anions and two N atoms of two symmetry-related 4,4'-bipyridine ligands within a strongly distorted octa-hedra. Two of the O atoms originate from one naphthalene-1,4-dicarboxyl-ate anion, whereas the remaining two O atoms derive from two symmetry-equivalent naphthalene-1,4-dicarboxyl-ate anions. Two Mn atoms are connected via the anions into dimers, which are further linked by the anions and the N-donor ligands into a three-dimensional coordination network.

Poly[(μ(2)-4,4'-bipyridine)(μ(2)-3,5-dicarboxybenzenesulfonato)silver(I)].

Project description:In the title compound, [Ag(C(8)H(5)O(7)S)(C(10)H(8)N(2))](n), the Ag atom is tetra-coordinated by two 4,4'-bipydidine (4,4'-bipy) N atoms and two monodentate sulfonate O atoms of the 5-sulfoisophthalic acid (H(3)sip) ligands. Adjacent Ag atoms are bonded through four sulfonate O atoms, forming a dinuclear unit with an Ag⋯Ag separation of 3.384 (5) Å; they are further linked together by the 4,4'-bipy lignds into a chain. Classical inter-molecular O-H⋯O and non-classical intra-molecular C-H⋯O hydrogen bonds are also observed in the two-dimensional supra-molecuar structure.

4,4'-Bipyridine acetic acid disolvate.

Project description:The crystal structure of the title compound, C(10)H(8)N(2)·2C(2)H(4)O(2), is built up from 4,4'-bipyridine and acetic acid mol-ecules linked by strong O-H?N hydrogen bonds. The 4,4'-bipyridine and the two acetic acid mol-ecules are further connected through weak C-H?O hydrogen bonds to form a supra-molecular two-dimensional network parallel to the (001) plane. The two pyridine rings make a dihedral angle of 31.8?(1)°.
