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.

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.

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. ?-? 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.

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.

Bis(2,2'-bipyridine){ethyl 4'-[N-(4-carbamoylphen-yl)carbamo-yl]-2,2'-bi-pyridine-4-carboxyl-ate}ruthenium(II) bis-[hexa-fluorido-phosphate(V)].

Project description:In the title compound, [Ru(C(10)H(8)N(2))(2)(C(21)H(18)N(4)O(4))](PF(6))(2), the Ru(II) complex cation reveals a slightly distorted octa-hedral coordination. The coordination bonds of the 4,4'-substituted bipyridyl donors [Ru-N = 2.038?(3) and 2.051?(3)?Å] are shorter than those of the 2,2'-bipyridyl donors [Ru-N1 = 2.065?(3)-2.077?(3)?Å], due to the electron-withdrawing effects of the substituents at the 4,4'-positions. The angles between the pyridyl planes of the three bipyridyl ligands are 1.5?(2), 6.3?(3) and 8.7?(2)°, respectively. The cations are connected by anions via N-H?F inter-actions.
