Diazido-bis[(1-methyl-1H-benzimidazol-2-yl)methanol-κN,O]manganese(II).

ABSTRACT: The title complex, [Mn(N(3))(2)(C(9)H(10)N(2)O)(2)], possesses crystallographically imposed twofold symmetry. The Mn(II) atom is coordinated by four N atoms and two O atoms in a distorted octa-hedral geometry. The crystal packing is stabilized by strong inter-molecular O-H⋯N hydrogen bonds.

Bis[(1-methyl-1H-benzimidazol-2-yl)methanol-κN,O]bis-(thio-cyanato-κN)cobalt(II) methanol solvate.

Project description:In the mononuclear title complex, [Co(NCS)(2)(C(9)H(10)N(2)O)(2)]·CH(3)OH, the cobalt(II) ion is surrounded by two (1-methyl-1H-benzimidazol-2-yl)methanol bidentate ligands and two thio-cyanate ligands, and exhibits a distorted octa-hedral coordination by four N atoms and two O atoms. The structure is consolidated by hydrogen bonds between the organic ligand, thio-cyanate anion and the uncoordinated methanol mol-ecule, leading to a chain along [100].

Project description:In the title complex, [Mn(CH(3)CO(2))(2)(C(11)H(9)N(5))], the Mn(II) atom is coordinated by the pyridine N atom and two pyrazole N atoms from a 2,6-bis-(pyrazol-3-yl)pyridine ligand and four O atoms from two bidentate acetate ligands.

Project description:In the title polymeric compound, [Mn(N(3))(2)(C(13)H(11)N(3))(2)](n), each Mn(II) centre is six-coordinated in an octahedral geometry by six N atoms from four 1-(4-pyridylmeth-yl)-1H-benzimidazole (L) ligands and two azide anions (N(3) (-)). Each of the Mn(II) ions lies on an inversion centre. The L ligands and N(3) (-) anions bridge adjacent Mn(II) centres, generating a polymeric chain running along the [110] direction. Adjacent polymeric chains are arranged in a two-dimensional network parallel to the (001) plane, linked by C-H⋯N hydrogen bonds.

Crystal structure of bis-[4-(di-methyl-amino)-pyridine-κN (1)]bis-(methanol-κO)bis-(thio-cyanato-κN)manganese(II).

Project description:The whole mol-ecule of the title compound, [Mn(NCS)2(CH3OH)2(C5H6N2)2], is generated by inversion symmetry. The Mn(II) ion, which is located on an inversion center, is coordinated by two 4-(di-methyl-amino)-pyridine ligands, two methanol ligands and two terminally N-bonded thio-cyanate anions, forming a slightly distorted octa-hedron. In the crystal, mol-ecules are linked by O-H⋯S hydrogen bonds, forming chains extending along the a-axis direction.

1,4-Bis(1H-benzimidazol-2-yl)benzene methanol monosolvate.

Project description:The asymmetric unit of the title compound, C(20)H(14)N(4)·CH(4)O, contains two independent half-mol-ecules, each located on an inversion centre, and a methanol solvent mol-ecule. The benzimidazolyl groups form different dihedral angles [24.0?(1) and 11.6?(1)°] with the plane of the central benzene ring in the two mol-ecules. In the crystal, a two-dimensional network is formed through N-H? N, N-H?O and O-H?N hydrogen-bonding inter-actions between the benzimidazole units and methanol solvent mol-ecules. ?-? stacking inter-actions also occur between the benzimidazole rings of adjacent mol-ecules, with centroid-centroid distances of 3.720?(14)?Å and inter-planar distances of 3.53?(1)?Å .

Chlorido-(2,2'-{[2-(1-methyl-1H-imidazol-2-yl-κN 3)imidazolidine-1,3-diyl-κN]bis-(methyl-ene)}bis-(1-methyl-1H-imidazole-κN 3))copper(II) perchlorate.

Project description:In the crystal structure of the title complex, [CuCl(C17H24N8)]ClO4, the copper(II) metal exhibits an N4Cl penta-coordinate environment in a distorted square-pyramidal geometry. Coordination to the metal centre occurs through the three 1-methyl-imidazole N atoms from the pendant groups, one amine N atom from the imidazolidine moiety and one chlorido anion. Inter-molecular inter-actions take place at two of the 1-methyl--imidazole rings in the form of parallel-displaced π-π stacking inter-actions forming chains parallel to the a axis. Three O atoms of the perchlorate anion are rotationally disordered between two orientations with occupancies of 0.5.

(1H-Benzimidazol-1-yl)methanol.

Project description:In the title compound, C(8)H(8)N(2)O, the N-CH(2) and CH(2)-O bond lengths can be correlated to the manifestation of an anomeric effect in the N-CH(2)-O moiety. In the crystal, inter-molecular O-H?N hydrogen bonds link the mol-ecules into zigzag chains, with graph-set motif C(6), parallel to [001]. These chains are further linked into sheets by weak nonclassical C-H?O hydrogen bonds.
