Hexa-?-chlorido-?(4)-oxido-tetra-kis-({1-[(pyridin-2-yl)meth-yl]-1H-benzimidazole-?N}copper(II)).

ABSTRACT: The title tetra-nuclear complex, [Cu(4)Cl(6)O(C(13)H(11)N(3))(4)], features a tetra-hedral arrangement of copper(II) ions bonded to the central O atom (site symmetry [Formula: see text]). Each of the six edges of the Cu(4) tetra-hedron is bridged by a chloride ion (one of which has site symmetry 2), so that each copper ion is linked to the other three metal ions through the central O atom and through three separate chloride-ion bridges. The fifth coord-ination position, located on the central Cu-O axis on the outside of the cluster, is occupied by an N atom of the mono-dentate 1-(pyridin-2-ylmeth-yl)-1H-benzimidazole ligand. The resulting coordination geometry of the metal ion is a distorted trigonal bipyramid with the O and N atoms in the axial positions. The dihedral angle between the benzimidazole ring system and the pendant pyridine ring is 61.0?(2)°.

Hexa-?(2)-chlorido-?(4)-oxido-tetra-kis-[(3-methyl-5-phenyl-1H-pyrazole-?N)copper(II)].

Project description:The title compound, [Cu(4)Cl(6)O(C(10)H(10)N(2))(4)], contains four Cu(II) atoms which are bridged by six chloride anions. The central O atom is located on a crystallographic fourfold roto-inversion axis. Each Cu(II) atom is coordinated by an N atom of a neutral monodentate 3-methyl-5-phenyl-pyrazole ligand, three Cl(-) anions, and one O(2-) anion. The geometry at each Cu(II) atom is distorted trigonal-bipyramidal, with the three Cl(-) ions in the equatorial plane and the N and O atoms in the axial positions.

Hexa-?2-chlorido-?4-oxido-tetra-kis[(morpholine-?N)copper(II)] methanol disolvate.

Project description:In the title solvate, [Cu4(?2-Cl)6(?4-O)(C4H9NO)4]·2CH3OH, each Cu(2+) ion in the tetra-nuclear complex has a trigonal-bipyramidal coordination arising from three bridging chloride ions in equatorial positions and the central ?4-O(2-) ion and morpholine N atom in axial positions. The morpholine rings adopt chair conformations, with the N-Cu bonds in equatorial orientations. In the crystal, the components are linked by N-H?O and O-H?O and O-H?Cl hydrogen bonds, which generate a three-dimensional network. One methanol mol-ecule is disordered over two sets of sites in a 0.642?(9):0.358?(9) ratio.

Di-?(3)-chlorido-tetra-?(2)-chlorido-dichloridobis(dimethyl-formamide-?O)hexa-kis-(1H-imidazole-?N)tetra-cadmium.

Project description:The centrosymmetric mol-ecule of the title complex, [Cd(4)Cl(8)(C(3)H(4)N(2))(6)(C(3)H(7)NO)(2)], contains four Cd(II) atoms, six imidazole, two dimethyl-formamide and eight chloride ligands. The structure shows a novel chloride-bridged tetra-nuclear cadmium quasi-cubane cluster. The coordination geometry of all Cd(II) atoms is distorted octa-hedral, with the two metal atoms in the asymmetric unit in different coordination environments. One of the Cd(2+) ions is coordinated by five Cl(-) ions and by one N atom from an imidazole ligand, while the second is coordinated by three chloride ligands, two N atoms from two imidazole ligands and one O atom from a dimethyl-formamide mol-ecule. Inter-molecular N-H?Cl hydrogen bonds link the mol-ecules into a two-dimensional polymeric structure parallel to the ab plane.

Tetra-?-oxido-tetra-kis{dioxido[3-(2-pyrid-yl)-1H-pyrazole]molybdenum(VI)}.

Project description:In the title compound, [Mo(4)O(12)(C(8)H(7)N(3))(4)], the Mo(VI) ion has a distorted octa-hedral coordination completed by two terminal O atoms, two ?-oxide atoms and two N atoms from one 3-(2-pyrid-yl)-1H-pyrazole ligand. It is noteworthy that in the tetranuclear unit ( symmetry), any three Mo(VI) atoms define a plane, and the fourth lies 1.8?(1)?Å out of that plane. The degree of linearity of the oxide bridges between two Mo atoms is 175.38?(13)°. Moreover, the N-H group forms an intra-molecular hydrogen bond (four per mol-ecule).

Bis{μ4-N-[phen-yl(pyridin-2-yl-aza-nid-yl)meth-yl]pyridin-2-aminido}tetra-kis(tetra-hydro-furan)-tetra-lithium.

Project description:The title complex, [Li4(C17H14N4)2(C4H8O)4], bears a novel tetra-dentate di-amido ligand. In the tetra-nuclear centrosymmetric complex mol-ecule, the metal atoms exhibit two kinds of coordination modes. The middle two Li(+) cations are coord-inated by four N (ligand) and one O (tetra-hydro-furan, THF) atoms, resulting in a distorted square-pyramidal geometry. The outer two Li(+) cations are in distorted tetra-hedral environments consisting of three N (ligand) and one O (THF) atoms. The Li-N bond lengths vary from 2.020 (7) to 2.441 (6)Å.

?-2,3,5,6-Tetra-kis(pyridin-2-yl)pyrazine-bis-[(2,2':6',2''-terpyridine)-ruthenium(II)] tetra-kis-(hexa-fluoridophosphate) acetonitrile tetra-solvate.

Project description:In the title compound [Ru(2)(C(15)H(11)N(3))(2)(C(24)H(16)N(6))](PF(6))(4)·4CH(3)CN, two of the counter-ions and one of the solvent mol-ecules are disordered with occupancies for the major components between 0.57?(2) and 0.64?(1). The structure of the dinuclear tetracation exhibits significant distortion from planarity in the bridging 2,3,5,6-tetra-kis-(pyridin-2-yl)pyrazine (tppz) ligand, which has a saddle-like geometry with an average dihedral angle of 42.96?(18)° between adjacent pyridine rings. The metal-ligand coordination environment is nearly equivalent for the two Ru(II) atoms, which have a distorted octa-hedral geometry due to the restricted bite angle [157.57?(13)-159.28?(12)°] of their two mer-arranged tridendate ligands [2,2':6',2''-terpyridine (tpy) and tppz] orthogonal to each other. At the peripheral tpy ligands, the average Ru-N bond distance is 2.072?(4)?Å for the outer N atoms trans to each other (N(outer)) and 1.984?(1)?Å for the central N atoms (N(central)). At the bridging tppz ligand, the average metal-ligand distances are significantly shorter [2.058?(4)?Å for Ru-N(outer) and 1.965?(1)?Å for Ru-N(central)] as a result of both the geometric constraints and the stronger ?-acceptor ability of the pyrazine-centered bridge. The dihedral angle between the two tpy planes is 27.11?(6)°. The intra-molecular linear distance between the two Ru atoms is 6.6102?(7)?Å.

5,6-Dimethyl-2-(pyridin-2-yl)-1-[(pyri-din-2-yl)meth-yl]-1H-benzimidazole.

Project description:The title compound, C20H18N4, was obtained via the condensation of 4,5-di-methyl-benzene-1,2-di-amine with pyridine-2-carbaldehyde. The plane of the 2-(pyridin-2-yl) substitutent is canted by 2.75?(11)° from the plane of the benzimidazole system. The mol-ecule exhibits an S(6) C-H?N intra-molecular hydrogen-bond motif. In the crystal, C-H?N hydrogen bonds link pairs of mol-ecules related by a crystallographic inversion center, forming R 2 (2)(20) rings. Additional weak C-H?N hydrogen bonds result in C(9) chains parallel to [001].

Project description:The title compound, C(14)H(12)N(4)O(3)S, is an inter-mediate of Dexlansoprazole, a proton pump inhibitor (PPI) mainly developed for anti-ulcer activity. The absolute configuration of the title compound was determined as R. The crystal structure reveals that the mol-ecules form chains along the b axis through N-H?N and C-H?O hydrogen-bonded dimers. These chains are connected via weak C-H?O hydrogen bonds.

2-(Pyridin-4-yl)-1H-benzimidazole.

Project description:The title compound, C12H9N3, is an unhydrated analogue of the previously reported trihydrate. The mol-ecule is essentially planar, with a 3.62?(11)° angle between the pyridine and benzimidazole planes.
