Bis[4-chloro-2-(quinolin-8-yl-imino-meth-yl)phenolato-?(3) N,N',O]cobalt(III) trichlorido-methano-lcobaltate(II).

ABSTRACT: The reaction of 4-chloro-2-(quinolin-8-yl-imino-meth-yl)phenol (HClQP) with cobalt(II) dichloride hexa-hydrate in methanol/chloro-form under solvothermal conditions yielded the title compound, [Co(C16H10ClN2O)2][CoCl3(CH3OH)]. The Co(III) atom is six-coordinated in a slightly distorted octa-hedral geometry by four N atoms and two O atoms of two tridentate HClQP ligands, which are nearly perpendicular to each other, making a dihedral angle of 86.95°. The Co(II) atom is four-coordinated by three Cl atoms and one O atom from a methanol ligand in a distorted tetra-hedral geometry. The crystal packing is consolidated by inter-molecular O-H?Cl, C-H?Cl and C-H?O hydrogen bonds, forming a three-dimensional supra-molecular structure, in which [Co(II)Cl3(CH3OH)] anions are connected via O-H?Cl and C-H?Cl hydrogen bonds into centrosymmetric dimers. Neighboring cobalt(III) complexes form dimers through C-H?O hydrogen bonds, as well as ?-? stacking [centroid-centroid distances = 3.30?(2)?Å] between the planar quinoline systems of one HClQP ligand and the phenolate ring of another.

Crystal structure and Hirshfeld surface analysis of di-chlorido-(methanol-?O)bis-(2-methyl-pyridine-?N)copper(II).

Project description:In the title complex, [CuCl2(C6H7N)2(CH3OH)], the copper atom is five-coordinated by two nitro-gen atoms of 2-methyl-pyridine ligands, two chloro ligands and an oxygen atom of the methanol mol-ecule, being in a tetra-gonal-pyramidal environment with N and Cl atoms forming the basal plane. In the crystal, complex mol-ecules related by the twofold rotation axis are joined into dimeric units by pairs of O-H?Cl hydrogen bonds. These dimeric units are assembled through C-H?Cl inter-actions into layers parallel to (001).

Chlorido[1-(2-oxidophen-yl)ethyl-idene][tris-(3,5-dimethyl-pyrazol-1-yl)hydro-borato]iridium(III) chloro-form monosolvate.

Project description:In the title compound, [Ir(C15H22BN6)(C8H7O)Cl]·CHCl3, the Ir atom is formally trivalent and is coordinated in a slightly distorted octa-hedral geometry by three facial N atoms, one C atom, one O atom and one Cl atom. The Ir=Ccarbene bond is strong and short and exerts a notable effect on the trans-Ir-N bond, which is about 0.10?Å longer than the two other Ir-N bonds. The chloro-form solvent mol-ecule is anchored via a weak C-H?Cl hydrogen bond to the Cl atom of the Ir complex mol-ecule. In the crystal, the constituents adopt a layer-like arrangement parallel to (010) and are held together by weak inter-molecular C-H?Cl hydrogen bonds, as well as weak Cl?Cl [3.498?(2)?Å] and Cl?? [3.360?(4)?Å] inter-actions. A weak intra-molecular C-H?O hydrogen bond is also observed.

The structure displays intra-molecular O-H?O and O-H?Cl hydrogen bonds. Weak C-H?Cl hydrogen-bonding inter-actions connect the mol-ecules into a three-dimensional network.
