(Acetato-?O){bis-[(2,4-dimethyl-1H-pyrazol-1-yl)meth-yl][(pyridin-2-yl)meth-yl]amine}-cobalt(II) hexa-fluorido-phosphate.

ABSTRACT: In the title compound, [Co(CH(3)CO(2))(C(18)H(24)N(6))]PF(6), the Co(II) atom is penta-coordinated in a distorted trigonal-bipyramidal geometry by four N atoms from a tripodal ligand and one O atom from a monodentate acetate ligand. The crystal packing is stabilized by inter-molecular C-H?F and C-H?O hydrogen bonds.

Project description:In the title complex, [Co(CN)(2)(C(18)H(18)N(4))]PF(6), the Co(III) atom together with one of the pyridyl rings and two cyanide anions are located on a mirror plane, while the P atom is located on an inversion centre. The Co(III) atom exhibits an octa-hedral geometry, coordinated by four N atoms from the tris-(2-pyridyl-meth-yl)amine ligand with an average Co-N distance of 1.953?(2)?Å, and two cyanide C atoms with an average Co-C distance of 1.895?(2)?Å.

Crystal structure of {2,2'-[N,N'-bis-(pyridin-2-yl-meth-yl)cyclo-hexane-trans-1,2-diyldi(nitrilo)]di-acetato}-cobalt(III) hexa-fluorido-phosphate.

Project description:The title compound [Co(C22H26N4O4)]PF6, commonly known as [Co(bpcd)]PF6, where bpcd(2-) is derived from the historical ligand name N,N'-bis-(2-pyridyl-meth-yl)-trans-1,2-di-amino-cyclo-hexane-N,N'-di-acetate, crystallized by slow evaporation of a saturated aceto-nitrile solution in air. The cation of the hexa-fluorido-phosphate salt has the Co(III) atom in a distorted octa-hedral coordination geometry provided by an N4O2 donor atom set. The acetate groups, which are oriented trans with respect to each other, exhibit monodentate coordination whereas the pyridyl N atoms are coordinating in a cis configuration. The geometry of the cation is compared to the geometries of other di-amino di-acetate complexes with Co(III).

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

Project description: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.

Bis[3,5-di-fluoro-2-(pyridin-2-yl)phen-yl](4,4'-di-meth-oxy-2,2'-bi-pyridine)-iridium(III) hexa-fluorido-phosphate.

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.

(Naphthalene-2,3-diolato-κO,O')[tris-(2-pyridyl-meth-yl)amine-κN]cobalt(III) hexa-fluoridophosphate hemihydrate.

Project description:In the title complex, [Co(C(10)H(6)O(2))(C(18)H(18)N(4))]PF(6)·0.5H(2)O, the Co(III) ion is six-coordinated in a distorted octa-hedral geometry by four N atoms from a tris-(2-pyridyl-meth-yl)amine ligand and two O atoms from a naphthalene-2,3-diolate ligand.

In the crystal, the cations, anions and water mol-ecules are connected by O-H⋯O and O-H⋯F hydrogen bonds. π-π inter-actions are present between the pyridine rings [centroid-centroid distance = 3.814 (1) Å].

[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.

Project description:In the mononuclear title complex, [Ag(C(10)H(6)N(4))(2)]PF(6), two ?(2)N,N'-chelating 5-(pyridin-2-yl)pyrazine-2-carbonitrile ligands surround the Ag(I) atom, forming a distorted N(4) tetra-hedral coordination geometry.
