Hemi(4,4'-bipyridinium) hexa-fluorido-phosphate bis-(4-amino-benzoic acid) 4,4'-bipyridine monohydrate.

ABSTRACT: In the title compound, 0.5C(10)H(10)N(2) (2+)·PF(6) (-)·C(10)H(8)N(2)·2C(7)H(7)NO(2)·H(2)O, the cation is located on a center of symmetry. The crystal structure is determined by a complex three-dimensional network of inter-molecular O-H?O, O-H?N, N-H?N and N-H?F hydrogen bonds. ?-? stacking inter-actions between neighboring pyridyl rings are also present; the centroid-centroid distance is 3.643?(5)?Å. The hexa-fluoridophosphate anion is disordered over two positions with site-occupancy factors of ca 0.6 and 0.4.

Bis(4,4'-bipyridinium) dodeca-tungsto-silicate 4,4'-bipyridine hexa-hydrate.

Project description:The title compound, (C(10)H(10)N(2))(2)[SiW(12)O(40)]·C(10)H(8)N(2)·6H(2)O or (4,4'-bipyH(2))(2)[SiW(12)O(40)].(4,4'-bipy)·6H(2)O (4,4'-bipy is 4,4'-bipyridine), was prepared under hydro-thermal conditions. The asymmetric unit contains a discrete Keggin-type [SiW(12)O(40)](4-) anion (located on a twofold axis), one 4,4'-bipy (located on a twofold axis), two (4,4'-bipyH(2))(2+) cations and six uncoordinated water mol-ecules. The polyoxoanion is constructed from a central SiO(4) tetra-hedron which shares its O atoms with four trinuclear W(3)O(13) groups, each of which is made up of three edge-sharing WO(6) octa-hedra. The water mol-ecules and [SiW(12)O(40)](4-) anions are linked through hydrogen bonds.

1,1'-Dimethyl-4,4'-bipyridinium bis-(tetra-fluorido-borate).

Project description:In the title compound, C(12)H(14)N(2) (2+)·2BF(4) (-), the cation has a centre of symmetry at the mid-point of the central C-C bond. π-π inter-actions, with a shortest atom-to-atom distance of 3.757 (4) Å, extend the crystal structure into a one-dimensional supra-molecular chain.

Bis(2,2'-bipyridine)(pyridin-2-olato)ruthenium(II) hexa-fluorido-phosphate benzene hemisolvate.

Project description:In the title compound, [Ru(C(5)H(4)NO)(C(10)H(8)N(2))(2)]PF(6)·0.5C(6)H(6), the Ru(2+) cation has a distorted octa-hedral RuN(5)O coordination environment. This complex is more distorted than the closely related ruthenium complex containing a pyridine-2-thiol-ate ligand [Santra et al. (1997 ?). J. Chem. Soc. Dalton Trans. pp. 1387-1393]. The distortion is caused by the difference in size between the O and S atoms. The benzene solvent mol-ecule is situated on a twofold rotation axis.

4,4'-Bipyridinium bis(perchlorate)-4-aminobenzoic acid-4,4'-bipyridine-water (1/4/2/2).

Project description:In the structure of the title compound, C(10)H(10)N(2) (2+)·2ClO(4) (-)·4C(7)H(7)NO(2)·2C(10)H(8)N(2)·2H(2)O, the 4,4'-bipyridinium cation has a crystallographically imposed centre of symmetry. The cation is linked by N-H?N hydrogen bonds to adjacent 4,4'-bipyridine mol-ecules, which in turn inter-act via O-H?N hydrogen bonds with 4-amino-benzoic acid mol-ecules, forming chains running parallel to [30]. The chains are further connected into a three-dimensional network by N-H?O and O-H?O hydrogen-bonding inter-actions involving the perchlorate anion, the water mol-ecules and the 4-amino-benzoic acid mol-ecules. In addition, ?-? stacking inter-actions with centroid-centroid distances ranging from 3.663?(6) to 3.695?(6)?Å are present. The O atoms of the perchlorate anion are disordered over two sets of positions, with refined site occupancies of 0.724?(9) and 0.276?(9).

Bis(2,2'-bipyridine)[1,9-bis(diphenylphos-phanyl)-1,2,3,4,6,7,8,9-octahydropyrim-ido[1,2-a]pyrimidin-5-ium]ruthenium(II) hexa-fluorido-phosphate dibromide di-chloro-methane disolvate monohydrate.

Project description:In the cation of the title complex, [Ru(C31H32N3P2)(C10H8N2)2](PF6)(Br)2·2CH2Cl2·H2O, the ruthenium ion is coordinated in a distorted octa-hedral geometry by two 2,2'-bi-pyridine (bpy) ligands and a chelating cationic N-di-phenyl-phosphino-1,3,4,6,7,8-hexa-hydro-2-pyrimido[1,2-a]pyrimidine [(PPh2)2-hpp] ligand. The tricationic charge of the complex is balanced by two bromide and one hexa-fluorido-phosphate counter-anions. The compound crystallized with two mol-ecules of di-chloro-methane (one of which is equally disordered about a Cl atom) and a water mol-ecule. In the crystal, one of the Br anions bridges two water mol-ecules via O-H⋯Br hydrogen bonds, forming a centrosymmetric diamond-shaped R (4) 2(8) motif. The cation and anions and the solvent mol-ecules are linked via C-H⋯F, C-H⋯Br, C-H⋯Cl and C-H⋯O hydrogen bonds, forming a three-dimensional network.

cis-Bis(2,2'-bipyridine-?(2) N,N')carbonyl-chloridoruthenium(II) hexa-fluorido-phosphate.

Project description:In the title compound, [RuCl(C10H8N2)2(CO)]PF6, the Ru(II) atom is coordinated in a distorted octa-hedral geometry by four N atoms of the bipyridine ligands, a carbonyl C atom and a chloride ion. The carbonyl and chloride ligands in the cation adopt a mutually cis arrangement and these are disordered over two sets of sites with site occupancies of 0.721?(6) and 0.279?(6). The Ru-N bond length [2.117?(2)?Å] trans to the carbonyl ligand is slightly longer than the average of the other Ru-N bond lengths (2.08?Å), which can be explained by the expected trans influence of the carbonyl group. In the crystal, weak C-H?F inter-actions are observed between the complex cation and the PF6(-) anion, leading to the formation of a three-dimensional supramolecular structure. The crystal studied was an inversion twin with twin fractions of 0.78?(4) and 0.22?(4).

1,1'-Bis(diisobutyl-phosphino)cobalto-cenium hexa-fluorido-phosphate.

Project description:In the title compound, [Co(C(13)H(22)P)(2)]PF(6), the Co(III) atom is sandwiched between two (diisobutyl-phosphino)cyclo-penta-dienenyl ligands. The two diisobutyl-phophine units are trans to each other with respect to the Co(III) metal center. The PF(6) (-) anion links the cobaltocenium cations via weak C-H?F hydrogen bonds into a chain running along the b axis. The chains are further linked by C-H?F hydrogen bonds, forming a layer extending parallel to the (10) plane.

(Benzoato-κO)(benzoic acid-κO)(4,4'-dimethyl-2,2'-bipyridine-κN,N')hydroxidocopper(II) monohydrate.

Project description:In the structure of the title complex, [Cu(C(7)H(5)O(2))(OH)(C(12)H(12)N(2))(C(7)H(6)O(2))]·H(2)O, the Cu(II) ion is penta-coordinated in a tetra-gonal-pyramidal geometry with one O atom of a hydroxide group, one O atom of a benzoate anion and two N atoms of a 4,4'-dimethyl-2,2'-bipyridine ligand occupying the basal plane, and one O atom of a benzoic acid mol-ecule located at the apical site. The title complex was refined with a metal-coordinated OH group and a 'free' benzoic acid molecule, although it can be assumed that the proton is delocalized between the OH and the COOH group. The uncoordinated water mol-ecule is equally disordered over two positions. The structure displays O-H⋯O hydrogen bonding.

1,1'-Dimethyl-4,4'-bipyridinium bis-(triiodide).

Project description:In the title compound, C(12)H(14)N(2) (2+)·2I(3) (-), the 1,1'-dimethyl-4,4'-bipyridinium (DMBP) dication is charge balanced by two triiodide ions. The DMBP dication is planar within 0.010 (5) Å. The asymmetric unit contains only half of the dication, the other half being generated by an inversion center. Weak C-H⋯I inter-actions link the ions into sheets parallel to (121).

catena-Poly[4,4'-bipyridinium [[diaqua-disulfatocadmium(II)]-?-4,4'-bipyridine-?N:N'] dihydrate].

Project description:The title compound, {(C(10)H(10)N(2))[Cd(SO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)]·2H(2)O}(n), consists of anionic chains of the Cd complex, diprotonated 4,4'-bipyridinium cations and uncoordinated water mol-ecules. In the anionic chain, the Cd atom lies on a center of inversion in an octa-hedral geometry. The midpoint of the coordinated bipyridine also resides on a center of inversion, as does the non-coordinated bipyridinium counterion. O-H?O and N-H?O hydrogen bonding inter-actions and ?-? stacking inter-actions in the structure are responsible for the supra-molecular assembly.
