Dichloridobis[2-(1-hydrazinylideneeth-yl)pyrazine-?N(1)]zinc.

ABSTRACT: In the structure of the title complex, [ZnCl(2)(C(6)H(8)N(4))(2)], the Zn(II) atom has a distorted octa-hedral geometry. Two cis Cl(-) ions and four N atoms belonging to two different 2-(1-hydrazinylideneeth-yl)pyrazine ligands coordinate the Zn(II) atom, forming two five-membered Zn-N-C-C-N rings. The dihedral angle between the planes of these metallocycles is 88.13?(4)°. The organic ligands are essentially planar (r.m.s. deviations from planarity = 0.072 and 0.040?Å). Inter-molecular N-H?N and N-H?Cl inter-actions join the mol-ecules into a three-dimensional framework.

Project description:The title mononuclear Zn(II) complex, [ZnCl(2)(C(15)H(13)N(5))(2)], is isotypic with the previously reported Hg(II) complex. The Zn(II) atom is located on a twofold rotation axis and has a distorted tetra-hedral environment of two Cl atoms and two N atoms from two heterocyclic ligands. In the crystal, complex mol-ecules are extended by inter-molecular π-π inter-actions [centroid-centroid distance = 3.792 (2) Å] into a three-dimensional supra-molecular network.

Dichloridobis{2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-benzimidazole-?N (3)}-zinc(II).

Project description:In the title complex, [ZnCl2(C10H9N5)2], the Zn(II) ion is coordinated by two N atoms from two 2-[(1H-1,2,4-triazol-1-yl)meth-yl]-1H-benzimidazole (tmb) ligands and by two chloride ligands in a slightly distorted tetra-hedral geometry. In the tmb ligands, the benzimidazole rings systems are essentially planar, with maximum deviations from the mean plane of 0.021?(3) and 0.030?(3)?Å, and form dihedral angles of 73.2?(2) and 83.5?(2)° with the triazole rings. In the crystal, N-H?N hydrogen bonds link complex mol-ecules into chains along [010]. In addition, weak C-H?Cl and C-H?N hydrogen bonds complete a three-dimensional network. Two weak intra-molecular C-H?Cl hydrogen bonds are also observed.

Diiodido(2,3,5,6-tetrapyridin-2-yl-pyrazine-?N,N,N)zinc(II).

Dichloridobis(4-fluoro-aniline-κN)zinc.

Project description:In the title compound, [ZnCl(2)(C(6)H(6)FN)(2)], the Zn(II) atom has a slightly distorted tetra-hedral geometry, being coordinated by the N atoms of two 4-fluoro-aniline mol-ecules and the two Cl(-) anions. The two benzene rings are almost perpendicular to one another, making a dihedral angle of 89.96 (13)°. In the crystal, mol-ecules are linked via pairs of N-H⋯Cl hydrogen bonds, forming chains propagating along the b axis. These chains are in turn linked via a second pair of N-H⋯Cl hydrogen bonds, forming a two-dimensional network parallel to the ab plane. The title compound crystallizes in the space group Pca2(1) and exhibits weak second harmonic generation (SHG) properties.

Dichloridobis(phenanthridine-?N)zinc(II).

Project description:In the mol-ecule of the title compound, [ZnCl(2)(C(13)H(9)N)(2)], the Zn(II) atom is four-coordinated in a distorted tetra-hedral configuration by two N atoms from two phenanthridine ligands and by two terminal Cl atoms. The dihedral angle between the planes of the phenanthridine ring systems is 69.92?(3)°. An intra-molecular C-H?Cl inter-action results in the formation of a planar five-membered ring, which is oriented at a dihedral angle of 8.32?(3)° with respect to the adjacent phenanthridine ring system. In the crystal structure, ?-? contacts between the phenanthridine systems [centroid-centroid distances = 3.839?(2), 3.617?(1) and 3.682?(1)?Å] may stabilize the structure. Two weak C-H?? inter-actions are also found.
