Crystal structure of high-spin tetra-aqua-bis-(2-chloro-pyrazine-κN (4))iron(II) bis-(4-methyl-benzene-sulfonate).

ABSTRACT: The title salt, [Fe(II)(C4H3ClN2)2(H2O)4](C7H7O3S)2, contains a complex cation with point group symmetry 2/m. The high-spin Fe(II) cation is hexa-coordinated by four symmetry-related water and two N-bound 2-chloro-pyrazine mol-ecules in a trans arrangement, forming a distorted FeN2O4 octa-hedron. The three-dimensional supra-molecular structure is supported by inter-molecular O-H⋯O hydrogen bonds between the complex cations and tosyl-ate anions, and additional π-π inter-actions between benzene and pyrazine rings. The methyl H atoms of the tosyl-ate anion are equally disordered over two positions.

Aqua-(3-methyl-isoquinoline-κN)silver(I) 4-amino-benzene-sulfonate.

Project description:In the title compound, [Ag(C(10)H(9)N)(H(2)O)](C(6)H(6)NO(3)S), the Ag(I) atom is two-coordinated by one N atom from a 3-methyl-isoquinoline ligand and one water mol-ecule. The 4-amino-benzene-sulfonate counter-anion does not show any bonding inter-actions with the Ag(I) atom. The compound exhibits a three-dimensional supra-molecular structure constructed by hydrogen bonds. Adjacent isoquinoline groups form π-π inter-actions, with a centroid-centroid distance of 3.54 (1) Å. The crystal studied was an inversion twin.

Bis[(E)-1-methyl-4-styrylpyridinium] 4-chloro-benzene-sulfonate iodide.

Project description:In the title compound, 2C(14)H(14)N(+)·C(6)H(4)ClO(3)S(-)·I(-), each cation exists in an E configuration with respect to the ethenyl bond. The dihedral angle between the pyridinium and benzene rings is 3.98?(6)° in one of the cations and 9.88?(7)° in the other. The two cations are arranged in an anti-parallel manner with ?-? inter-actions between pyridinium and benzene rings [centroid-centroid distance = 3.5805?(8)?Å]. The benzene ring of the anion makes dihedral angles of 61.20?(6) and 64.25?(6)° with the pyridinium rings of the two cations. In the crystal, the cations are stacked in an anti-parallel manner along the a axis, while the anions are linked into chains along the same direction. The ions are linked into a three-dimensional network by C-H?I and C-H?O hydrogen bonds and C-H?? inter-actions. The crystal under investigation was an inversion twin, with a ratio of 61.7?(5):38.3?(5) for the two components.

μ-Pyrazine-bis-[tetra-aqua-cadmium(II)] μ-pyrazine-bis-[tetra-acetato-cadmium(II)].

Project description:In the title dinuclear ionic complex, [Cd(2)(C(4)H(4)N(2))(H(2)O)(8)][Cd(2)(CH(3)CO(2))(8)(C(4)H(4)N(2))], the cation and anion are disordered equally over a site with symmetry mmm. The Cd(II) ions and the N atoms of the bridging pyrazine ligand lie on the inter-section of two crystallographic mirror planes. The C atoms of the bridging pyrazine ligand lie on one of these mirror planes, and the acetate groups and water mol-ecules lie across the inter-secting mirror planes. Each Cd(II) atom in the cation is five-coordinated by four O atoms from four water mol-ecules and one N atom from the bridging pyrazine ligand, whereas each Cd(II) in the anion is nine-coordinated by four pairs of O atoms from the bidentate acetate ligands and one N atom from the bridging pyrazine ligand. In the crystal structure, each anion is surrounded by eight nearest-neighbour cations and vice versa. The crystal structure is stabilized by ionic inter-actions as well as by C-H⋯O inter-actions.

Bis[μ-1,2-bis-(1H-imidazol-1-ylmethyl)benzene-κN:N]disilver(I) bis-(4-amino-2,5-dichloro-benzene-sulfonate) tetra-hydrate.

Project description:The asymmetric unit of the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(6)H(4)Cl(2)NO(3)S)(2)·4H(2)O, contains one-half of each of two independent dicationic units, two 4-amino-2,5-dichloro-benzene-sulfonate anions and four water mol-ecules. Each centrosymmetric dicationic unit has a dinuclear structure in which two Ag(I) atoms are bridged by two 1,2-bis-(1H-imidazol-1-yl-meth-yl)benzene ligands in a slightly distorted linear coordination geometry. The 4-amino-2,5-dichloro-benzene-sulfonate anion does not coordinate with the Ag(I) center, acting only as a counteranion. In the crystal structure, inter-molecular O-H⋯O and N-H⋯O hydrogen bonds form a three-dimensional network.
