Crystal structure of {N-[(6-bromo-pyridin-2-yl)(phen-yl)methyl-idene]-2,6-di-methyl-aniline-?²N,N'}di-chlorido-zinc di-chloro-methane hemisolvate.

ABSTRACT: The solvated title compound, [ZnCl₂(C₂₀H₁₇BrN₂)]·0.5CH₂Cl₂, comprises a bidentate imino-pyridine ligand and two Cl atoms bound to a zinc²⁺ cation in a distorted tetra-hedral arrangement. The chelate bond lengths are consistent with localized C=N double bonds and a C-C single bond, as expected for an unreduced ligand bound to a closed-shell transition metal cation. Apart from weak nonclassical C-H?Cl hydrogen bonds between the complex mol-ecules and the disordered solvent mol-ecules (occupancy = 0.5), no further significant inter-molecular inter-actions are observed.

Project description:The asymmetric unit of the title compound, [Ir(C17H11F2N2)3]·0.5CH3(CH2)4CH3·0.5CH2Cl2, comprises one IrIII atom, three 2,6-di-fluoro-3-[5-(2-fluoro-phen-yl)pyridin-2-yl]pyridin-4-yl ligands and half each of an n-hexane and a di-chloro-methane solvent mol-ecule located about crystallographic inversion centres. The IrIII atom displays a distorted octa-hedral coordination geometry, having three C,N-chelating 2,6-di-fluoro-3-[5-(2-fluoro-phen-yl)pyridin-2-yl]pyridin-4-yl ligands arranged in a meridional manner. The IrIII ion lies almost in the equatorial plane [deviation = 0.0069 (15) Å]. The average distance [2.041 (3) Å] of Ir-C bonds is slightly shorter than that [2.076 (3) Å] of Ir-N bonds. A variety of intra- and inter-molecular C-H⋯F and C-H⋯π hydrogen bonds, as well as inter-molecular C-F⋯π inter-actions, contribute to the stabilization of the mol-ecular and crystal structures, and result in the formation of a two-dimensional network parallel to the ab plane. No inter-actions between n-hexane solvent mol-ecules and the other components in the title compound are observed.

Crystal structure of trans-bis-{4-bromo-N-[(pyridin-2-yl)-methyl-idene]aniline-κ(2) N,N'}di-chlorido-ruthenium(II).

Project description:In the title complex, [RuCl2(C12H9BrN2)2] or [RuCl2(PM-BrA)2] (PM-BrA = 4-bromo-N-(2'-pyridyl-methyl-ene)aniline), the Ru(II) cation is located on a centre of inversion and is surrounded by four N atoms of two PM-BrA ligands in the equatorial plane and by two Cl atoms in a trans axial arrangement, displaying a distorted octa-hedral coordination environment. Two C atoms in the benzene ring of the PM-BrA ligand are equally disordered over two sets of sites. The benzene and pyridine rings of the PM-BrA ligand are oriented at dihedral angles of 62.1 (10) and 73.7 (11)° under consideration of the two orientations of the disordered benzene ring. In the crystal, the complex mol-ecules are connected via C-H⋯Cl hydrogen-bonding inter-actions into a layered arrangement parallel (100). C-H⋯Br hydrogen bonding and weak aromatic π-π stacking inter-actions complete a three-dimensional supra-molecular network.

The benzene and pyridine rings are oriented at a dihedral angle of 56.7?(6)°.

Di-aqua-bis-{?-1,5-bis-[(pyridin-2-yl)methyl-idene]carbonohydrazide(1-)}di-?-chlorido-tetra-chlorido-tetra-zinc(II).

Project description:A tetra-nuclear ZnII complex, [Zn4(C13H11N6O)2Cl6(H2O)2] or {[Zn2(HL)(H2O)(Cl2)](?Cl)2[Zn2(HL)(H2O)(Cl)]}2, was synthesized by mixing an equimolar amount of a methanol solution containing ZnCl2 and a methanol solution containing the ligand H2 L [1,5-bis-(pyridin-2-yl-methyl-ene)carbono-hydrazide]. In the tetra-nuclear complex, each of the two ligand mol-ecules forms a dinuclear unit that is connected to another dinuclear unit by two bridging chloride anions. In each dinuclear unit, one ZnII cation is penta-coordinated in a N2OCl2 in a distorted square-pyramidal geometry, while the other ZnII cation is hexa-coordinated in a N3OCl2 environment with a distorted octa-hedral geometry. The basal plane around the penta-coordinated ZnII cation is formed by one chloride anion, one oxygen atom, one imino nitro-gen atom and one pyridine nitro-gen atom with the apical position occupied by a chloride anion. The basal plane of the hexa-coordinated ZnII cation is formed by one chloride anion, one hydrazinyl nitro-gen atom, one imino nitro-gen atom and one pyridine nitro-gen atom with the apical positions occupied by a water oxygen atom and a bridged chloro anion from another dinuclear unit, leading to a tetra-nuclear complex. A series of intra-molecular C-H?Cl hydrogen bonds is observed in each tetra-nuclear unit. In the crystal, the tetra-nuclear units are connected by inter-molecular C-H?Cl, C-H?O and N-H?O hydrogen bonds, forming a planar two-dimensional structure in the ac plane.

The Zn(II) ion shows distorted tetra-hedral geometry, being coordinated by an imidazole N atom, the aniline N atom, and two chlorido ligands. The packing features N-H⋯O, N-H⋯Cl, C-H⋯Cl hydrogen bonding.

Di-?-chlorido-bis-(chlorido-{N'-[phen-yl(pyridin-2-yl-?N)methyl-idene]pyridine-2-carbohydrazide-?(2) N',O}cadmium).

Project description:The title compound, [Cd2Cl4(C18H14N4O)2], was obtained from the reaction of Cd(NO3)2·4H2O with 2-phenyl-pyridine-keton picolinoyl hydrazone and sodium chloride. Each Cd(2+) cation is coordinated by two N atoms and one O atom of the tridentate ligand and three chloride anions, forming a distorted CdNOCl3 octahedron. Each pair of adjacent metal cations is linked by two bridging chloride ligands, resulting in a dinuclear complex unit. The mol-ecular conformation is stabilized by intra-molecular N-H?N and C-H?O hydrogen bonds. In the crystal, mol-ecules are linked by nonclassical C-H?O and C-H?Cl hydrogen bonds into a three-dimensional network. In addition, ?-? stacking inter-actions [centroid-centroid distances = 3.777?(2) and 3.631?(2)?Å] contribute to the stabilization of the crystal packing.

Synthesis, crystal structure and photophysical properties of chlorido-[2-(2',6'-di-fluoro-2,3'-bipyri-din-6-yl-κN 1)-6-(pyridin-2-yl-oxy-κN)phenyl-κC 1]platinum(II).

Project description:The title compound, [Pt(C21H12F2N3O)Cl], crystallizes with two crystallographically independent mol-ecules (A and B) in the asymmetric unit, which adopt similar conformations. The PtII atoms in both mol-ecules adopt distorted square-planar geometries, coordinated by one C and two N atoms from the tridentate 2',6'-di-fluoro-6-[3-(pyridin-2-yl-oxy)phen-yl]-2,3'-bi-pyridine ligand and a chloride anion: the C and Cl atoms are trans. In the crystal, C-H⋯Cl/F hydrogen bonds, F⋯π and weak π-π stacking inter-actions between adjacent A and B mol-ecules and between pairs of inversion-related B mol-ecules lead to the formation of a two-dimensional supra-molecular network lying parallel to the ab plane. The sheets are stacked along the c-axis direction and linked by F⋯π and weak π-π stacking inter-actions between pairs of inversion-related A mol-ecules, forming a three-dimensional supra-molecular network. The photoluminescence quantum efficiency of the title compound in the blue-green region of the visible region (λmax = 517 and 544 nm) is estimated to be ∼0.2-0.3, indicating that the title compound could be a suitable candidate as the emitting material in organic light-emitting diode (OLED) applications.
