Bis(1-benzyl-1H-benzimidazole-κN (3))di-chlorido-zinc.

ABSTRACT: In the title compound, [ZnCl2(C14H12N2)2], the Zn(II) atom exhibits a distorted tetra-hedral coordination geometry involving two chloride anions and two N-atom donors from 1-benzyl-1H-benzimidazole ligands. In both ligands, the benzyl and benzimidazole rings are nearly perpendicular [dihedral angles = 81.7 (2) and 81.5 (2)°]. The two benzimidazole systems are essentially planar [maximum deviations = 0.015 (3) and 0.020 (2) Å] and form a dihedral angle of 78.09 (8)°. In the crystal, centrosymmetrically related mol-ecules are linked by pairs of C-H⋯Cl hydrogen bonds into chains parallel to the a axis.

Project description:The asymmetric unit of the crystal structure of the title compound, [Cd(2)Cl(4)(C(5)H(8)N(2))(3)](n), contains two Cd(II) cations, three 1-ethyl-1H-imidazole ligands, and four Cl(-) anions. The two Cd(II) atoms have quite different coordination environments: one is octa-hedrally coordinated by four Cl atoms and two N atoms from two 1-ethyl-1H-imidazole ligands, and the second is in a severely distorted fivefold coordination by four Cl atoms and one N atom from a 1-ethyl-1H-imidazole ligand. Adjacent Cd(II) cations are inter-connected alternately by pairs of chloride bridges, generating an infinite step-like chain along the a axis. One ethyl group of the 1-ethyl-1H-imidazole ligand is disordered over two sets of sites with a 0.668 (13):0.332 (13) site-occupancy ratio.

Di-μ-chlorido-bis-[chlorido(1,10-phenanthroline-κN,N')zinc(II)].

Project description:In the crystal structure of the title complex, [Zn(2)Cl(4)(C(12)H(8)N(2))(2)], each of the two five-coordinated Zn(II) atoms displays a strongly distorted trigonal-bipyramidal geometry defined by two N atoms from the chelate ligand and by one terminal and two bridging chloride anions. The crystal structure is stabilized by C-H⋯Cl inter-actions. There is inter-molecular π-π stacking between adjacent phenanthroline ligands, with a centroid-centroid distance of 3.151 (3) Å.

Di-μ-chlorido-bis-[chlorido(N,N-di-methyl-ethylenediamine-κN,N')zinc(II)].

Project description:The centrosymmetric dinuclear title compound, [Zn(2)Cl(4)(C(4)H(12)N(2))(2)], is isostructural with its previously reported Cu(II) analogue [Phelps, Goodman & Hodgson (1976 ▶). Inorg. Chem.15, 2266-2270]. In the title compound, each of the Zn(II) ions is coordinated by two N atoms from a chelating N,N-dimethyl-ethylenediamine ligand, two bridging Cl atoms and one terminal Cl atom. The coordination environment is distorted square-pyramidal. The Zn-Cl bond distances of the two bridging Cl atoms are distinctly different: the equatorial Cl atom exbibits a Zn-Cl distance of 2.318 (1) Å and the axial Cl atom exbibits a Zn-Cl distance of 2.747 (2) Å, which is significantly longer. The mol-ecule can thus be seen as a dimer of two nearly square-planar monomeric units which are related to each other by an inversion center located in the middle of the dimer. Within one monomeric unit, the Zn atom, the two N atoms and the two Cl atoms are almost coplanar, with a mean deviation of only 0.05 (1) Å from the associated least-squares plane. The Zn⋯Zn distance within the dimer is 3.472 (3) Å. N-H⋯Cl and C-H⋯Cl hydrogen-bond inter-actions connect neighboring mol-ecules with each other.

Di-bromido-bis-(2-methyl-1H-benzimidazole-κN (3))cadmium.

Project description:In the title compound, [CdBr2(C8H8N2)2], the Cd(II) atom has a distorted tetra-hedral coordination formed by the two imino N atoms of two 2-methyl-benzimidazole ligands and two terminal bromide ligands. The Cd(II) atom is slightly out of the benzimidazole planes by 0.320 (3) and 0.210 (3) Å. The dihedral angle between the benzimidazole planes is 71.6 (2)°. In the crystal, mol-ecules are linked by N-H⋯Br hydrogen bonds into puckered layers parallel to (001).

Bis(4-amino-benzene-sulfonamide-κN (4))di-chlorido-zinc.

Project description:In the title compound, [ZnCl2(C6H8N2O2S)2], the Zn(II) ion lies on a twofold rotation axis and has a slightly distorted tetra-hedral coordination geometry, involving two Cl atoms and two N atoms from the amino groups attached directly to the benzene rings [Zn-Cl = 2.2288 (16) Å and Zn-N = 2.060 (5) Å]. The dihedral angle between the benzene rings is 67.1 (3)°. The crystal packing can be describe as layers in a zigzag arrangement parallel to (001). The amine H atoms act as donor atoms and participate in inter-molecular N-H⋯O and N-H⋯Cl hydrogen bonds, forming a three-dimensional network.

Di-μ-chlorido-bis-{chlorido[(R)/(S)-1,5-di-phenyl-3-(2-pyridyl-κN)-2-pyrazoline-κN]zinc(II)}.

Project description:In the centrosymmetric binuclear title compound, [Zn(2)Cl(4)(C(20)H(17)N(3))(2)], the coordination geometry of the Zn(II) ion can be described as a distorted ZnN(2)Cl(3) trigonal bipyramid (τ = 0.89), arising from the N,N'-bidentate ligand, a terminal chloride ion and two bridging chloride ions. The N atoms occupy one axial and one equatorial site and the terminal chloride ion occupies an equatorial site. The dihedral angle between the pyridine and pyrazole rings is 12.8 (2)°. In the crystal, aromatic π-π stacking [centroid-centroid separations = 3.812 (3) and 3.848 (3) Å] and C-H⋯Cl and C-H⋯π inter-actions help to establish the packing.

Bis[2-(2-amino-ethyl)-1H-benzimidazole-κN,N]zinc(II) bis-(perchlorate).

Project description:In the title compound, [Zn(C(9)H(11)N(3))(2)](ClO(4))(2), the Zn(II) atom resides on a crystallographic twofold axis and is coordinated by two benzimidazole N [Zn⋯N = 1.993 (4) Å] and two amine N atoms [Zn⋯N = 2.036 (4) Å] in a distorted tetra-hedral geometry. The crystal packing is dominated by N-H⋯O inter-actions involving the perchlorate anions and π-π stacking inter-actions with an inter-planar separation of 3.42 Å. A weak C-H⋯O inter-action is also present.

The dihedral angle between the two benzene rings is 85.3 (2)° The Zn atom lies on a twofold rotation axis. The ethyl substituents are disordered over two sets of sites in a 0.74 (2):0.26 (2) ratio. In the crystal, N-H⋯Cl hydrogen bonds link the mol-ecules into sheets perpendicular to the a axis. C-H⋯Cl inter-actions also occur.

Di-μ-thio-cyanato-κN:S;κS:N-bis-[bis-(2-methyl-1H-benzimidazole-κN)(thio-cyanato-κN)cadmium(II)].

Project description:The title compound, [Cd(2)(NCS)(4)(C(8)H(8)N(2))(4)], is a centrosymmetric dinuclear cadmium(II) complex in which each two metal ions are linked by a pair of thio-cyanate N:S-bridges. Two 2-methyl-benzimidazole N-atom donors and one terminal thio-cyanate N atom complete a highly distorted square-pyramidal geometry around the Cd atom. In the crystal structure, two N-H⋯S hydrogen-bonding inter-actions occur, resulting in a three-dimensional polymeric structure. The apical 2-methyl-benzimidazole ring and its symmetry-related counterpart are arranged in an anti-parallel manner with a centroid-centroid separation of 3.6050 (14) Å, indicative of a π-π inter-action.
