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

ABSTRACT: 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].

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.

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.

cis-Bis(1,10-phenanthroline-?N,N')bis-(thio-cyanato-?N)magnesium(II).

Project description:The title compound, [Mg(NCS)(2)(C(12)H(8)N(2))(2)], has been synthesized from the hydro-thermal reaction of MgCl(2), KSCN, 1,10-phenanthroline and H(2)O. Its structure is isotypic with the Mn(II), Fe(II), Co(II), Ni(II), Cu(II) and Zn(II) analogues. The Mg(II) cation has a slightly distorted octa-hedral geometry containing four N atoms from two 1,10-phenanthroline mol-ecules and two N atoms from two thio-cyanate anions. The asymmetric unit contains one-half mol-ecule, and the complete complex has 2 symmetry.

Diaqua-bis-(1,10-phenanthroline-?N,N')manganese(II) sulfate hexa-hydrate.

Project description:In the title compound, [Mn(C(12)H(8)N(2))(2)(H(2)O)(2)]SO(4)·6H(2)O, the complex cations assemble into positively charged sheets parallel to (010) via inter-molecular ?-? stacking inter-actions with a mean interplanar distance of 3.410?(6) along [100] and 3.465?(5)?Å along [001]. The sulfate anions and uncoordinated water mol-ecules are inter-connected between these layers by hydrogen bonds, forming negatively charged layers which are linked to the positive layers through O-H?O hydrogen bonds, forming a three-dimensional architecture. Both the positive and negative sheets are stacked along [010] in an ?ABAB? sequence, the A layers being shifted by 1/2a along [100] with respect to the B layers. One of the uncoordinated water molecules is equally disordered over two positions.

?-2,3,5,6-Tetra-kis(pyridin-2-yl)pyrazine-bis-[(2,2':6',2''-terpyridine)-ruthenium(II)] tetra-kis-(hexa-fluoridophosphate) acetonitrile tetra-solvate.

Project description:In the title compound [Ru(2)(C(15)H(11)N(3))(2)(C(24)H(16)N(6))](PF(6))(4)·4CH(3)CN, two of the counter-ions and one of the solvent mol-ecules are disordered with occupancies for the major components between 0.57?(2) and 0.64?(1). The structure of the dinuclear tetracation exhibits significant distortion from planarity in the bridging 2,3,5,6-tetra-kis-(pyridin-2-yl)pyrazine (tppz) ligand, which has a saddle-like geometry with an average dihedral angle of 42.96?(18)° between adjacent pyridine rings. The metal-ligand coordination environment is nearly equivalent for the two Ru(II) atoms, which have a distorted octa-hedral geometry due to the restricted bite angle [157.57?(13)-159.28?(12)°] of their two mer-arranged tridendate ligands [2,2':6',2''-terpyridine (tpy) and tppz] orthogonal to each other. At the peripheral tpy ligands, the average Ru-N bond distance is 2.072?(4)?Å for the outer N atoms trans to each other (N(outer)) and 1.984?(1)?Å for the central N atoms (N(central)). At the bridging tppz ligand, the average metal-ligand distances are significantly shorter [2.058?(4)?Å for Ru-N(outer) and 1.965?(1)?Å for Ru-N(central)] as a result of both the geometric constraints and the stronger ?-acceptor ability of the pyrazine-centered bridge. The dihedral angle between the two tpy planes is 27.11?(6)°. The intra-molecular linear distance between the two Ru atoms is 6.6102?(7)?Å.

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

Project description: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.

(Formato-κO)bis-(1,10-phenanthroline-κN,N')copper(II) formate hexa-hydrate.

Project description:In the title compound, [Cu(CHO(2))(C(12)H(8)N(2))(2)]CHO(2)·6H(2)O, the Cu atom is coordinated in a distorted trigonal-bipyramidal fashion by an O atom of the formate ligand and four N atoms of two phenanthroline ligands with Cu-O and Cu-N distances of 2.020 (3) and 1.978 (3)-2.177 (3) Å, respectively. Hydrogen bonding O-H⋯O between water molecules and between water anions as well as π-π inter-actions [centroid-centroid distances between phen rings = 3.38 (7) and 3.40 (5) Å] are responsible for the supra-molecular assembly.

(Heptanedioato-κO,O')bis-(1,10-phenanthroline-κN,N')zinc(II) hexa-hydrate.

Project description:In the crystal structure of the title compound, [Zn(C(7)H(10)O(4))(C(12)H(8)N(2))(2)]·6H(2)O, the Zn(II) atom is coordinated by two carboxyl-ate O atoms of a mono-bidentate chelating pimelate anion (pimelic acid is hepta-nedioic acid) and four N atoms of two phenanthroline ligands, forming a considerably distorted octa-hedral ZnN(4)O(2) coordination geometry. The complexes are assembled into a three-dimensional network via C-H⋯O, C-H⋯π and π-π inter-actions. The mean inter-planar distance between adjacent phenanthroline ligands is 3.399 (2) Å.

Bis(2-phenyl-4,6-di-2-pyridyl-1,3,5-triazine-κN,N,N)ruthenium(II) bis(hexa-fluoridophosphate).

Project description:The asymmetric unit of the title compound, [Ru(C(19)H(13)N(5))(2)](PF(6))(2), consists of an Ru(II) complex cation and two hexa-fluoridophosphate anions. The Ru(II) atom is coordinated by three N atoms from the two outer pyridine and the central triazine rings of each of two tridentate ligands in a distorted octa-hedral environment. The ligands are approximately orthogonal to one another, with a dihedral angle of 88.34 (2)° between planes through the three six-membered rings of the two ligands. The pendant phenyl substituents are almost coplanar with the triazine rings to which they are bound, with dihedral angles of 5.41 (9) and 14.90 (10)°. This is reflected in the previously reported photophysical results with an increased lifetime of the triplet metal to ligand charge transfer ((3)MLCT) excited state [Fang, Taylor, Hanan, Loiseau, Passalacqua, Campagna, Nierengarten & Van Dorsselaer (2002). J. Am. Chem. Soc.124, 7912-7913].

A double salt of iodo-bis-muthate: cis-aqua-iodidobis(1,10-phenanthroline)cobalt(II) tris-(1,10-phenanthroline)cobalt(II) trans-hexa-?(2)-iodido-hexa-iodidotribismuthate(III).

Project description:In the title complex, [Co(C(12)H(8)N(2))(3)][CoI(C(12)H(8)N(2))(2)(H(2)O)][Bi(3)I(12)], conventionally abbreviated [Co(phen)(3)][CoI(phen)(2)(H(2)O)][Bi(3)I(12)], where phen is 1,10-phenanthroline, the Co(II) atom in one cation is coordinated by six N atoms from three phen ligands in an octa-hedral coordination while the Co(II) atom in the other cation is coordinated octa-hedrally by four N atoms from two phen ligands, one water O atom and one I atom. In the anion, three Bi(III) ions adopt an octa-hedral coordination constructed by six I(-) ligands. The three BiI(6) octa-hedra are fused together through trans face-sharing.
