Poly[(?(2)-2,2'-bipyridine-?N:N')bis-(?(3)-2,2,2-trifluoro-acetato-?O:O:O')disilver(I)].

ABSTRACT: In the title salt, [Ag(2)(CF(3)CO(2))(2)(C(10)H(8)N(2))](n), which may also be regarded as a coordination polymer if long Ag?O inter-actions are considered, each of the N atoms of the somewhat twisted 2,2'-bipyridine mol-ecule [N-C-C-N = -27.5?(4)°] binds to an Ag atom, and each of the carboxyl-ate ligands is tridentate, linking to three Ag atoms. The bidentate carboxyl-ate O atoms bridge the same two Ag atoms, resulting in the formation of Ag(2)O(2) rings. These rings are bridged by the 2,2'-bipyridine ligands, forming a chain along the b axis. The chains are linked into double chains via the remaining Ag-O bonds and Ag?Ag contacts. As a consequence of the Ag?Ag contacts, the NO(4) donor set about each Ag atom is heavily distorted. Finally, the chains are linked into a three-dimensional network by a combination of C-H?O and C-H?F inter-actions.

5,5'-Bis[(2,2,2-trifluoro-eth-oxy)meth-yl]-2,2'-bipyridine.

Project description:The complete molecule of the title compound, C(16)H(14)F(6)N(2)O(2), is generated by crystallographic inversion symmetry, which results in two short intramolecular C-H?N hydrogen-bond contacts per molecule. In the crystal, aromatic ?-? stacking [centroid-centroid distance = 3.457?(2)?Å] and weak C-H?? inter-actions occur. A short H?H [2.32?(3)?Å] contact is present.

Bis[2-(benzimidazol-2-ylsulfan-yl)acetato]bis-(2,2'-bipyridine)cadmium(II).

Project description:In the structure of the title compound, [Cd(C(9)H(7)N(2)O(2)S)(2)(C(10)H(8)N(2))(2)], the complex mol-ecules are located on a crystallographic twofold rotation axis and the Cd(II) ion is octa-hedrally coordinated by two chelating 2,2'-bipyridine ligands and two O atoms from the carboxyl-ate groups of two 2-(benzimidazol-2-ylsulfan-yl)acetate ligands. The two carboxyl-ate ligands adopt a cis configuration with respect to each other. Within each of these ligands, the imidazole fragments are bent back in a loop towards the acetyl groups, forming intra-molecular N-H?O hydrogen bonds, which help to stablilize the mononuclear complex. Adjacent mol-ecules are further linked by weak C-H?O hydrogen bonds, resulting in a chain along the c axis.

Bis(2,2'-bipyridine)(2-hy-droxy-2,2-diphenyl-acetato)-copper(II) nitrate dihydrate.

Project description:In the title complex, [Cu(C(14)H(11)O(3))(C(10)H(8)N(2))(2)]NO(3)·2H(2)O, the Cu(II) atom is coordinated by four N atoms from two 2,2'-bipyridine ligands and two O atoms from one benzilate ligand in a distorted octa-hedral geometry. A supra-molecular network is formed via inter-molecular O-H?O and C-H?O hydrogen-bonding inter-actions. ?-? stacking inter-actions between neighboring pyridine rings are also present, the centroid-centroid distance being 3.808?(2)?Å.

trans-Diaqua-bis(2,2'-bipyridine-?N,N')ruthenium(II) bis-(trifluoro-methane-sulfonate).

Project description:The title compound, trans-[Ru(bpy)(2)(H(2)O)(2)](CF(3)SO(3))(2) (bpy = 2,2'-bipyridine, C(10)H(8)N(2)), crystallized from the decomposition of an aged aqueous solution of a dimeric complex of cis-Ru(bpy)(2) in 0.1 M triflic acid. The Ru(II) ion is located on a crystallographic inversion center and exhibits a distorted octa-hedral coordination with equivalent ligands trans to each other. The Ru-O distance is 2.1053?(16)?Å and the Ru-N distances are 2.0727?(17) and 2.0739?(17)?Å. The bpy ligands are bent, due to inter-ligand steric inter-actions between H atoms of opposite pyridyl units across the Ru center. The crystal structure exhibits an extensive hydrogen-bonding network involving the water ligands and the trifluoromethane-sulfonate counter-ions within two-dimensional layers, although no close hydrogen-bond inter-actions exist between different layers.

Poly[diaqua-bis(2,2'-bipyridine)tris-(?(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.

Project description:In the title compound, [Zn(C(14)H(11)O(2))(2)(C(10)H(8)N(2))(H(2)O)(2)](n), the Zn(II) ion lies on a crystallographic inversion center and is in a slightly distorted octahedral coordination enviroment. 4,4'-Bipyridine ligands act as bridging ligands, connecting Zn(II) ions into a chain along the b-axis direction. In the crystal structure, these chains are linked by inter-molecular O-H?O hydrogen bonds to form a two-dimensional network parallel to the ab plane.

Bis(2,2'-bipyridyl-?N,N')(nitrato-?O,O')(trifluoro-acetato-?O)cadmium(II).

Project description:In the title complex, [Cd(C(2)F(3)O(2))(NO(3))(C(10)H(8)N(2))(2)], the Cd(II) ion is hepta-coordinated by two chelating 2,2'-bipyridyl ligands [Cd?N 2.370?(6)-2.416?(6)?Å], one carboxyl-ate O atom [Cd?O 2.290?(6)?Å] from the trifluoro-acetate ligand and two O atoms [Cd?O 2.386?(6), 2.633?(6)?Å] from a chelating nitrate anion. The trifluoro-methyl fragment is rotationally disordered between two orientations in a 0.640?(7):0.360?(7) ratio. In the crystal, weak inter-molecular C-H?O hydrogen bonds contribute to the crystal packing stability.

Bis(acetato-?(2)O,O')(4,4'-dimethyl-2,2'-bipyridine-?(2)N,N')-zinc.

Project description:The mol-ecular structure of the title compound, [Zn(CH(3)COO)(2)(C(12)H(12)N(2))], consists of isolated mol-ecules bis-ected by a twofold rotation axis which goes through the Zn(II) cation and halves the organic base through the central C-C bond. The Zn(II) ion is coordinated by two N atoms from one mol-ecule of the aromatic base and four O atoms from two bidentate, symmetry-related acetate anions, which coordinate asym-metrically [Zn-O distances of 2.058?(2) and 2.362?(3)?Å], while the two Zn-N bond distances are equal as imposed by symmetry [2.079?(2)?Å]. The crystal structure is supported by a number of weak C-H?O inter-actions and C-H?? contacts, with no ?-? inter-actions present, mainly hindered by the substituent methyl groups and the relative mol-ecular orientation. The result is a three-dimensional structure in which each mol-ecule is linked to eight different neighbors.

catena-Poly[[bis-(?(2)-4-amino-benzene-sulfonato-?O:O)disilver]-bis-(?(2)-4,4'-bipyridine-?N:N')].

Project description:In the title compound, [Ag(2)(C(6)H(6)NO(3)S)(2)(C(10)H(8)N(2))(2)](n), the Ag(I) atom is four-coordinated by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) and two O atoms from two independent 4-amino-benzene-sulfonate (ABS) ligands. The two inter-chain Ag(I) atoms are bridged by two independent ABS ligands through weak Ag-O bonds and Ag?Ag attractions, forming a ladder-like chain coordination polymer [Ag(2)(ABS)(2)(bipy)(2)](n) parallel to [001], which is further linked to generate a two-dimensional structure via N-H?O hydrogen-bonding inter-actions.

Project description:In the title compound, [Cu(C(2)H(3)O(2))(2)(C(12)H(12)N(2))(2)]·H(2)O, the Cu(II) atom exhibits a distorted octa-hedral coordination geometry, defined by two N atoms from one 4,4'-dimethyl-2,2'-bipyridine ligand and four O atoms from two acetate ligands. In the crystal, O-H?O hydrogen bonds are observed between the coordinated carboxyl-ate O atoms and the solvent water mol-ecule.
