Bis[?-3,5-bis-(pyridin-2-yl)-1H-pyrazole]-bis-[di-bromido-iron(III)].

ABSTRACT: The title dinuclear complex, [Fe2Br4(C13H9N4)2], which lies on an inversion center, features two approximately planar bis-(pyridin-2-yl)pyrazole (bpypz(-)) ligands [maximum deviation = 0.082?(3)?Å] and four bromide ions. Each Fe(III) ion is octa-hedrally coordinated by four N atoms of two bpypz(-) ligands and two Br ions. ?-? stacking inter-actions [centroid-centroid distances = 3.7004?(17)-4.0123?(18)?Å] are observed between pyridyl and pyrazole rings, and between pyridyl and pyridyl rings of adjacent complex mol-ecules.

The title dinuclear complex, [Fe2Br4(C13H9N4)2], which lies on an inversion center, features two approximately planar bis-(pyridin-2-yl)pyrazole (bpypz(-)) ligands [maximum deviation = 0.082 (3) Å] and four bromide ions. Each Fe(III) ion is octa-hedrally coordinated by four N atoms of two bpypz(-) ligands and two Br ions. π-π stacking inter-actions [centroid-centroid distances = 3.7004 (17)-4.0123 (18) Å] are observed between pyridyl and pyrazole rings, and between pyridyl and pyridyl rings of a ...[more]

Crystal structure of bis-{(3,5-di-methyl-pyrazol-1-yl)di-hydro-[3-(pyridin-2-yl)pyrazol-1-yl]-borato}iron(II).

Project description:The structure determination of [Fe(C13H15BN5)2] was undertaken as part of a project on the modification of the recently published spin-crossover (SCO) complex [Fe{H2B(pz)(pypz)}2] (pz = pyrazole, pypz = pyridyl-pyrazole). To this end, a new ligand was synthesized in which two additional methyl groups are present. Its reaction with iron tri-fluoro-methane-sulfonate led to a pure sample of the title compound, as proven by X-ray powder diffraction. The asymmetric unit consists of one complex mol-ecule in a general position. The FeII atom is coordinated by two tridentate N-binding {H2B(3,5-(CH3)2-pz)(pypz)}- ligands. The Fe-N bond lengths range between 2.1222 (13) and 2.3255 (15) Å, compatible with FeII in the high-spin state, which was also confirmed by magnetic measurements. Other than a very weak C-H⋯N non-classical hydrogen bond linking individual mol-ecules into rows extending parallel to [010], there are no remarkable inter-molecular inter-actions.

Di-μ-chlorido-bis-{bis-[3,5-dimethyl-pyrazol-1-yl-κN)methane]iron(II)} bis-[tetra-chloridoferrate(III)].

Project description:In the title complex, [Fe(2)Cl(2)(C(11)H(16)N(4))(4)][FeCl(4)](2), the asymmetric unit is composed of one and a half units of [Fe(bdmpm)(2)Cl](2)(FeCl(4))(2)(bdmpm = bis(bis(3,5-dimethyl-pyrazol-1-yl)methane). The three independent Fe(II) atom have a distorted octa-hedral coordination geometry comprising two bridging chloride anions and four N atoms from two bis-(3,5-dimethyl-pyrazol-1-yl)methane ligands. The Fe(III) atom has a tetra-hedral coordination geometry comprising four chloride 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.

2,2'-(1-Phenyl-1H-pyrazole-3,5-di-yl)diphenol.

Project description:The title compound, C(21)H(16)N(2)O(2), was derived from 1-(2-hydroxy-phen-yl)-3-(-methoxy-phen-yl)propane-1,3-dione. The mol-ecular structure of the title compound is stabilized by an intra-molecular O-H?N hydrogen bond. The dihedral angle between the hydroxy-phenyl ring involved in this intra-molecular hydrogen bond and the pyrazole ring is significantly smaller [10.07?(6)°] than the dihedral angle between the pyrazole and the other hydroxy-phenyl ring [36.64?(5)°]. The benzene ring makes a dihedral angle of 54.95?(3)° with the pyrazole ring. The crystal packing is stabilized by O-H?O and O-H?N hydrogen bonds.
