Cis-(2,2'-Bipyridine-?(2)N,N')bis-(isonicotinamide-?N(1))palladium(II) bis-(hexa-fluoridophosphate).

ABSTRACT: In the title salt, [Pd(C(10)H(8)N(2))(C(6)H(6)NO)(2)](PF(6))(2), the Pd(II) atom is in a slightly distorted square-planar coordination environment by N atoms derived from two 4-pyridine-carboxamide ligands, in a cis disposition, and a chelating 2,2'-bipyridine mol-ecule. The monodentate ligands are nearly orthogonal to each other [dihedral angle = 85.7?(5)°] and to the PdN(4) plane [dihedral angles = 79.3?(3) and 78.7?(3)°]. The amide O atoms lie to opposite sides of the PdN(4) plane. The most notable feature of the crystal packing is a linear supra-molecular chain orientated approximately along [310] and formed via 16-membered {?HNCO}(4) motifs. These are connected into a three-dimensional network by amide-H?O, F inter-actions. Both PF(6) (-) anions are disordered over two positions of equal occupancy in respect of the F atoms.

cis-Bis(2,2'-bipyridine-κ(2)N,N')bis-(pyridin-4-amine-κN(1))ruthenium(II) bis-(hexa-fluoridophosphate) acetonitrile monosolvate.

Project description:In the title complex, [Ru(C(10)H(8)N(2))(2)(C(5)H(6)N(2))(2)](PF(6))(2)·CH(3)CN, the Ru(II) atom is bonded to two α-diimine ligands, viz. 2,2'-bipyridine, in a cis configuration and to two 4-amino-pyridine (4Apy) ligands in the expected distorted octa-hedral configuration. The compound is isostructural with [Ru(C(10)H(8)N(2))(2)(C(5)H(6)N(2))(2)](ClO(4))(2)·CH(3)CN [Duan et al. (1999 ▶). J. Coord. Chem.46, 301-312] and both structures are stabilized by classical hydrogen bonds between 4Apy ligands as donors and counter-ions and acetonitrile solvent mol-ecules as acceptors. Indeed, N-H⋯F inter-actions give rise to an inter-molecularly locked assembly of two centrosymmetric complex mol-ecules and two PF(6) (-) counter-ions, which can be considered as the building units of both crystal architectures. The building blocks are connected to one another through hydrogen bonds between 4Apy and the connecting pieces made up of two centrosymmetric motifs with PF(6) (-) ions and acetonitrile mol-ecules, giving rise to ribbons running parallel to [011]. 2(1)-Screw-axis-related complex mol-ecules and PF(6) (-) counter-ions alternate in helical chains formed along the a axis by means of these contacts.

Bis(2,2'-bipyridine)(5-isothio-cyanato-1,10-phenanthroline)ruthenium(II) bis-(hexa-fluoridophosphate) acetonitrile solvate.

Project description:The title compound, [Ru(C(10)H(8)N(2))(2)(C(13)H(7)N(3)S)](PF(6))(2)·CH(3)CN, was synthesized by the reaction of thio-phosgene and bis-(2,2'-bipyridine)(1,10-phenanthrolin-5-amine)ruthenium(II) bis-(hexa-fluoridophosphate). The Ru(II) atom adopts a slightly distorted octa-hedral RuN(6) coordinaton formed by four N atoms of two bipyridine ligands and by two N atoms of the 1,10-phenantroline ligand. The isothio-cyanate group is almost linear, with an N-C-S angle of 174.4?(6)°. Two of the three hexa-fluoridophosphate counter-anions are located on inversion centres.

Project description:The hemerythrin-type dinuclear title complex, [Ru2(CH3COO)2O(C10H8N2)2(C5H5N)2](PF6)2, consists of two Ru(III) ions with a six-coordinate octa-hedral geometry, bridged by an oxide and two acetate ligands, with a bidentate 2,2'-bipyridine ligand and a pyridine ligand bonding at terminal positions. The Ru-Ru distance and Ru-O-Ru angle are 3.2838?(3)?Å and 121.79?(7)°, respectively, and the average Ru-N(pyridine) bond length is 2.164?(8)?Å. Several C-H?F, C-H?O and C-H?N inter-actions generate a three-dimensional network in the crystal structure. ?-? stacking inter-actions [centroid-centroid distance = 3.6389?(3)?Å] between inversion-related 2,2'-bipyridine rings are also observed.

cis-Bis(2,2'-bipyridine-κN,N')dichloridocobalt(II) trihydrate.

Project description:In the title complex, [CoCl(2)(C(10)H(8)N(2))(2)]·3H(2)O, the Co(II) ion is situated on a twofold rotation axis and exhibits a slightly distorted octa-hedral geometry and is chelated by four N atoms of the two bidentate 2,2'-bipyridine ligands and two Cl(-) ions. The crystal packing is stabilized by hydrogen bonding formed between chloride ions and adjacent water mol-ecules. One of the two independent water molecules in the asymmetric unit is disordered over two sets of sites, each on a twofold rotation axis, in a 0.734 (17):0.269 (17) ratio.

(2,2'-Bipyridine-κN,N')bromido(1,4,7-trithia-cyclo-nonane-κS,S',S'')ruthenium(II) hexa-fluoridophosphate.

Project description:The title compound, [RuBr(C(10)H(8)N(2))(C(6)H(12)S(3))]PF(6) or [RuBr(bpy)([9]aneS(3))]PF(6) ([9]aneS(3) is 1,4,7-trithia-cyclo-nonane and bpy is 2,2'-bipyridine), exhibits a very similar octahedral coordination geometry for the Ru(2+) atom to that of its [RuCl(bpy)([9]aneS(3))](+) analogue, with only the chloride ligand being substituted by a bromide ligand. The presence of a PF(6) (-) anion (alongside with the coordinated bromide ligand) promotes the existence of an extensive network of weak C-H⋯X (X = F, Br) inter-actions.

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).

(4'-Ethynyl-2,2':6',2''-terpyridine)(2,2':6',2''-terpyridine)-ruthenium(II) bis-(hexa-fluoridophosphate) acetonitrile disolvate.

Project description:The title heteroleptic bis--terpyridine complex, [Ru(C(15)H(11)N(3))(C(17)H(11)N(3))](PF(6))(2)·2CH(3)CN, crystallized from an acetonitrile solution as a salt containing two hexa-fluoridophosphate counter-ions and two acetonitrile solvent mol-ecules. The Ru(II) atom has a distorted octa-hedral geometry due to the restricted bite angle [157.7?(3)°] of the two mer-arranged N,N',N''-tridendate ligands, viz. 2,2':6',2''-terpyridine (tpy) and 4'-ethynyl-2,2':6',2''-terpyridine (tpy'), which are essentially perpendicular to each other, with a dihedral angle of 87.75?(12)° between their terpyridyl planes. The rod-like acetyl-ene group lies in the same plane as its adjacent terpyridyl moiety, with a maximum deviation of only 0.071?(11)?Å from coplanarity with the pyridine rings. The mean Ru-N bond length involving the outer N atoms trans to each other is 2.069?(6)?Å at tpy and 2.070?(6)?Å at tpy'. The Ru-N bond length involving the central N atom is 1.964?(6)?Å at tpy and 1.967?(6)?Å at tpy'. Two of the three counter anions were refined as half-occupied.

cis-Bis(acetonitrile-?N)bis-(2,2'-bipyridine-?N,N')ruthenium(II) tetra-fluoridoborate.

Project description:In the cation of the title compound, [Ru(CH(3)CN)(2)(C(10)H(8)N(2))(2)](BF(4))(2), the Ru(II) atom is six-coordinated in a distorted octa-hedral geometry by the N atoms of the two 2,2'-bipyridine (bpy) ligands and two cis-arranged acetonitrile mol-ecules. The dihedral angles formed by the pyridine rings of the bpy ligands are 8.86?(12) and 10.12?(14)°. In the crystal, the cations and anions are linked by C-H?F hydrogen bonds into a three-dimensional network.

cis-Bis(1,10-phenanthroline-?(2)N,N')bis-(pyridin-4-amine-?N(1))ruthenium(II) bis-(hexa-fluoridophosphate).

Project description:In the title complex, [Ru(C(12)H(8)N(2))(2)(C(5)H(6)N(2))(2)](PF(6))(2), the Ru(II) atom is bonded to two ?-diimine ligands, viz. 1,10-phenanthroline (phen), in a cis configuration, in addition with with two 4-amino-pyridine (4Apy) ligands, resulting in a distorted octa-hedral coordination geometry. N-H?F hydrogen-bonding inter-actions play an important role in the crystal assembly: 2(1)-screw-axis-related complex mol-ecules and PF(6) (-) counter-ions alternate in helical chains formed along the a axis by means of these contacts. N-H?? contacts (H?centroid = 3.45?Å) are responsible for cross-linking between the helical chains along [001].
