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

ABSTRACT: 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 ?-? stacking inter-actions complete a three-dimensional supra-molecular network.

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

Project description:A tetra-nuclear ZnII complex, [Zn4(C13H11N6O)2Cl6(H2O)2] or {[Zn2(HL)(H2O)(Cl2)](μCl)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.

Crystal structure of {N-[(6-bromo-pyridin-2-yl)(phen-yl)methyl-idene]-2,6-di-methyl-aniline-κ2N,N'}di-chlorido-zinc di-chloro-methane hemisolvate.

Project description: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.

Crystal structures and Hirshfeld surface analysis of trans-bis-(thio-cyanato-κN)bis-{2,4,6-trimethyl-N-[(pyridin-2-yl)methyl-idene]aniline-κ2 N,N'}manganese(II) and trans-bis-(thio-cyanato-κN)bis-{2,4,6-trimethyl-N-[(pyridin-2-yl)methyl-idene]aniline-κ 2 N,N'}nickel(II)).

Project description:Two new mononuclear metal complexes involving the bidentate Schiff base ligand 2,4,6-trimethyl-N-[(pyridin-2-yl)methyl-idene]aniline (C15H16N2 or PM-TMA), [Mn(NCS)2(PM-TMA)2] (I) and [Ni(NCS)2(PM-TMA)2] (II), were synthesized and their structures determined by single-crystal X-ray diffraction. Although the title compounds crystallize in different crystal systems [triclinic for (I) and monoclinic for (II)], both asymmetric units consist of one-half of the complex mol-ecule, i.e. one metal(II) cation, one PM-TMA ligand, and one N-bound thio-cyanate anion. In both complexes, the metal(II) cation is located on a centre of inversion and adopts a distorted octa-hedral coordination environment defined by four N atoms from two symmetry-related PM-TMA ligands in the equatorial plane and two N atoms from two symmetry-related NCS- anions in a trans axial arrangement. The tri-methyl-benzene and pyridine rings of the PM-TMA ligand are oriented at dihedral angles of 74.18 (7) and 77.70 (12)° for (I) and (II), respectively. The subtle change in size of the central metal cations leads to a different crystal packing arrangement for (I) and (II) that is dominated by weak C-H⋯S, C-H⋯π, and π-π inter-actions. Hirshfeld surface analysis and two-dimensional fingerprint plots were used to qu-antify these inter-molecular contacts, and indicate that the most significant contacts in packing are H⋯H [48.1% for (I) and 54.9% for (II)], followed by H⋯C/C⋯H [24.1% for (I) and 15.7% for (II)], and H⋯S/S⋯H [21.1% for (I) and 21.1% for (II)].

[4-Bromo-N-(pyridin-2-yl-methyl-idene)aniline-κ(2)N,N']iodido(triphenyl-phosphane-κP)copper(I).

Project description:In the title compound, [CuI(C(12)H(9)BrN(2))(C(18)H(15)P)], the Cu(I) ion is bonded to one I atom, one triphenyl-phosphane P atom and two N atoms of the diimine ligand in a distorted tetra-hedral geometry. The Schiff base acts as a chelating ligand and coordinates to the Cu(I) atom via two N atoms. In the diimine ligand, the dihedral angle between the pyridine and bromo-phenyl rings is 19.2 (2)°. In the crystal, mol-ecules are connected by π-π stacking inter-actions between inversion-related pyridine rings [centroid-centroid distance = 3.404 (3) Å].

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.

Di-μ(2)-chlorido-bis-[chlorido(η-hexa-methyl-benzene)ruthenium(II)].

Project description:Dimeric mol-ecules of the title compound, [Ru(2)Cl(4)(C(12)H(18))(2)], are located on a crystallographic centre of inversion with one mol-ecule in the asymmetric unit. The hexa-methyl-benzene rings are in an η(6)-coordination to the ruthenium centres, which are bridged by two chloride ligands. In addition, the ruthenium centres are bonded to another chloride ligand. The aromatic rings and the Ru(2)Cl(2) four-membered ring enclose a dihedral angle of 55.85 (6)°.

trans-Di-chlorido-bis-(pyridazine-?N)palladium(II).

Project description:The title compound, [PdCl2(C4H4N2)2], contains two crystallographically unique complexes; the Pd(II) atom lies on an inversion center in both cases. The two pyridazine units bonded to the Pd(II) atom are thus coplanar although dihedral angles within each complex are different. In one complex, the angle between the ring plane and Pd-Cl bond is almost perpendicular [89.4?(1)°], while the other is tilted with an angle of 60.0?(1)°. In the crystal, weak C?H-N hydrogen bonds and C?H-Cl inter-actions connect the two independent complex mol-ecules.
