Catena-Poly[[silver(I)-?-N-[(pyridin-2-yl)meth-yl]pyridine-3-amine-?(2) N:N'] hexa-fluorido-phosphate].

ABSTRACT: In the title polymeric complex, {[Ag(C11H11N3)]PF6} n , the Ag(I) ion is two-coordinated in a nearly linear coordination geometry [N-Ag-N = 175.98?(9)°] by two pyridine N atoms from two symmetry-related N-[(pyridine-2-yl)meth-yl]pyridine-3-amine ligands. Each Ag(I) ion is bridged by the ligands, forming a helical chain propagating along the b-axis direction. The right- and left-handed helical chains are alternately arranged via Ag?Ag [3.2639?(5)?Å] and ?-? stacking inter-actions [centroid-centroid distance = 3.523?(1)?Å], resulting in the formation of a two-dimensional supra-molecular network extending parallel to (101). Weak Ag?F inter-actions [longest Ag?F inter-action = 3.153?(2)?Å], as well as N-H?F and C-H?F hydrogen-bonding inter-actions, occur between the helical chains and the anions.

Project description:The title cyclo-metalated distorted octa-hedral iridium complex, [Ir(C11H6F2N)2(C12H12N2O2)]PF6, exhibits elongated Ir-N bonds to the dimeth-oxy bi-pyridine ligand [2.128 (3) and 2.136 (3) Å] where these nitro-gen atoms are trans to the Ir-C bonds of the two cyclo-metalating di-fluoro-phenyl-pyridine ligands. The angles between the mean planes of the phenyl and pyridyl fragments within the individual ligands range from 3.5 (2) to 11.4 (2)° to deviate slightly from coplanarity.

Poly[[{?(3)-tris-[2-(4-phenyl-1,2,3-triazol-1-yl)eth-yl]amine}silver(I)] hexa-fluorido-phosphate].

Project description:The title compound, {[Ag(L)]PF(6))(n) {L is tris-[2-(4-phenyl-1,2,3-triazol-1-yl)eth-yl]amine, C(30)H(30)N(10)}, consists of alternating two-dimensional cationic layers of [Ag(L)](+) and anionic PF(6) (-) layers. Each Ag(I) atom is three coordinated in a T-shaped geometry by three N atoms from three ligands. Each ligand links three Ag(I) atoms, generating a two-dimensional network structure with two different metallacycles, A and B. In A, eight coordination units from four ligands connect four Ag(I) atoms, forming a 48-membered ring. In B, four coordination units from two ligands link two Ag(I) atoms, forming a 24-membered ring. Each B ring is surrounded by four A rings, and each A ring has four A and four B rings as neighbours. This cationic layer thus generates a 4.8(2) topology network, with each Ag(I) centre and ligand acting as a three-connected topological node.

catena-Poly[[[(2-pyridone-κO)silver(I)]-μ-2-pyridone-κO:O] hexa-fluorido-phosphate].

Project description:The asymmetric unit of the polymeric title salt, {[Ag(C(5)H(5)NO)(2)]PF(6)}(n), comprises an Ag(I) cation (located on a twofold axis), two 2-pyridone ligands (with distinct coordination modes), and half a PF(6) (-) anion (situated on a centre of inversion). The Ag(I) atom is in an approximately octa-hedral AgO(6) coordination geometry, which is stabilized by intra-molecular N-H⋯O hydrogen bonds. The result of the bridging mode of the 2-pyridone ligand is the formation of a supra-molecular chain along the c axis; these are consolidated in the crystal by C-H⋯F inter-actions.

Bis{2-[(diisopropyl-phosphan-yl)amino]-pyridine-?N,P}copper(I) hexa-fluorido-phosphate.

Project description:The crystal structure of the title compound, [Cu(C(11)H(19)N(2)P)(2)]PF(6), is composed of discrete [Cu(PN-iPr)(2)](+) cations [PN-iPr is 2-(diisopropyl-phosphanyl-amino)-pyridine] and PF(6) (-) anions. The Cu(I) atom is bis-chelated by two independent PN-iPr ligands. It has a distorted tetra-hedral coordination by two P atoms [Cu-P = 2.2277?(4) and 2.2257?(4)?Å] and two pyridine N atoms [Cu-N = 2.0763?(11) and 2.0845?(12)?Å]. Bond angles about Cu vary from 85.11?(3) (P-Cu-N) to 130.37?(2)° (P-Cu-P). In the crystal, N-H?F hydrogen bonds link the Cu complexes and the PF(6) (-) anions into continuous chains, which show a cross-bedded spatial arrangement. In addition, several weaker C-H?F inter-actions contribute to the coherence of the structure.

Crystal structure of an AgI inter-calation compound: catena-poly[[silver(I)-?-N-(pyridin-3-ylmeth-yl)pyridin-3-amine-?2N:N'] hexa-fluorido-phosphate aceto-nitrile disolvate].

Project description:The asymmetric unit in the title compound, [Ag(C11H11N3)]PF6·2CH3CN or {[AgL]·PF6·2CH3CN} n , L = N-(pyridin-3-ylmeth-yl)pyridin-3-amine, comprises one AgI atom, one L ligand, two aceto-nitrile solvent mol-ecules and one PF6- anion disordered over two orientations in a 0.567?(11):0.433?(11) ratio. Each AgI atom is coordinated by two pyridine N atoms from two L ligands in a slightly distorted linear coordination geometry [N-Ag-N = 170.55?(8)°]. Each L ligand bridges two AgI ions, resulting in the formation of a zigzag chain propagating along the [101] direction. In the crystal, Ag?Ag contacts [3.3023?(5)?Å] and inter-molecular ?-? stacking inter-actions [centroid-to-centroid distance = 3.5922?(15)?Å] between the pyridine rings link these chains into a corrugated layer parallel to the ([Formula: see text]01) plane. The layers are stacked with a separation of 10.4532?(5)?Å, and aceto-nitrile solvent mol-ecules and PF6- anions as guests are inter-calated between the layers. The layers are connected through several N/C-H?F hydrogen bonds and P-F?? inter-actions [F?ring centroid = 3.241?(8)?Å] between the layer and the inter-calated guests and between the inter-calated guests, forming a three-dimensional supra-molecular network.

catena-Poly[[silver(I)-μ-N-(pyridin-3-ylmeth-yl)pyridine-2-amine-κ(2) N:N'] tri-fluoro-methane-sulfonate].

Project description:In the asymmetric unit of the title polymeric complex, {[Ag(C11H11N3)](CF3SO3)} n , there are two Ag(I) atoms, two N-(pyridin-3-ylmeth-yl)pyridine-2-amine ligands (A and B) and two CF3SO3 (-) anions. One Ag(I) atom is coordinated by two pyridine N atoms from two symmetry-related A ligands in a geometry slightly distorted from linear [N-Ag-N = 173.2 (3)°], forming a left-handed helical chain, while the other Ag(I) atom is coordinated by two pyridine N atoms from two symmetry-related B ligands in a bent arrangement [N-Ag-N = 157.1 (3)°], forming a right-handed helical chain. Both helical chains have the same pitch length [10.4007 (7) Å], propagate along the b-axis direction and are alternately arranged via Ag⋯Ag [3.0897 (12) Å] and π-π stacking inter-actions [centroid-centroid distances = 3.564 (7) and 3.518 (6) Å], resulting in the formation of a two-dimensional supra-molecular network extending parallel to the ab plane. Inter-molecular N-H⋯O, C-H⋯O and C-H⋯F hydrogen-bonding inter-actions occur between the helical chains and the anions.

[Bis-(2-pyrid-yl-?N)amine]chlorido(?-hexa-methyl-benzene)-ruthenium(II) hexa-fluorido-phosphate dichloro-methane solvate.

Project description:In the title half-sandwich complex, [RuCl(?(6)-C(12)H(18))(C(10)H(9)N(3))]PF(6)·CH(2)Cl(2), the ruthenium(II) ion is four-coordinated by a chloro, a hexa-methyl-benzene and a bidentate N,N'-chelating di(pyridin-2-yl)amine ligand. In the crystal, the amino N-H group forms a hydrogen bond with the chloro ligand of a neighbouring complex, thus forming chains along the b axis. Weak inter-molecular C-H?F and C-H? Cl contacts are also observed.
