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

ABSTRACT: 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.

Project description:In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(7)H(4)O(6)S)·CH(3)OH·3H(2)O, the complex dication has a binuclear structure in which each Ag(I) ion is two-coordinated in a slightly distorted linear coordination geometry.

In the dication, π-π inter-actions are observed between the imidazole rings with centroid-centroid distances of 3.472 (3) and 3.636 (3) Å. In the crystal, the uncoordinated water mol-ecules, anions and methanol solvent mol-ecules are linked into chains along the b axis by O-H⋯O hydrogen bonds. In addition, π-π inter-actions are observed between the benzene rings of the IBI ligands, with a centroid-centroid distance of 3.776 (2) Å. The sulfonate group is disordered over two orientations with occupancies of 0.676 (12) and 0.324 (12).

Project description:In the crystal of the title compound, C(6)H(6)Cl(2)N(+)·C(6)H(4)ClO(3)S(-), the 2,5-dichloroanilinium cations and 4-chlorobenzenesulfonate anions are located on a crystallographic mirror plane and are connected by N-H?O hydrogen bonds.

Bis[?-1,2-bis-(1H-imidazol-1-ylmeth-yl)benzene-?N:N]disilver(I) bis-(4-carb-oxy-naphthalene-1-carboxyl-ate) tetra-hydrate.

Project description:In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(12)H(7)O(4))(2)·4H(2)O, the dinuclear dication has crystallographically imposed inversion symmetry. Each Ag(I) ion is bicoordinated in a slightly distorted linear coordination geometry by the N atoms of two ligands, resulting in the formation of a 22-membered metallamacrocycle. In the dication, ?-? inter-actions are observed between the imidazole rings, with centroid-centroid distances of 3.528?(3)?Å and dihedral angles of 9.92?(9)°. The crystal structure is stabilized by inter-molecular O-H?O hydrogen bonds and ?-? inter-actions involving the benzene rings of adjacent dications, with centroid-centroid distances of 3.651?(2)?Å.

Bis(2,5-dihydroxy-benzoato-κO)bis-(1,10-phenathroline-κN,N')cadmium(II) 1.25-hydrate.

Project description:In the crystal structure of the title compound, [Cd(C(7)H(5)O(4))(2)(C(12)H(8)N(2))(2)]·1.25H(2)O, the Cd(2+) cation is coordinated by two phenanthroline (phen) mol-ecules and two 2,5-dihydroxy-benzoate (dhba) anions in a distorted octa-hedral geometry. The centroid-centroid distances of 3.809 (2) and 3.680 (2) Å between nearly parallel pyridine rings of the phen ligands and the benzene rings of dhba anions indicate that the dhba anions are involved in π-π stacking in the crystal structure. The face-to-face separation of 3.35 (3) Å between parallel phen ring systems also suggests π-π stacking between adjacent complex mol-ecules. The crystal structure contains extensive O-H⋯O and C-H⋯O hydrogen bonding.

Project description:In the title complex, [Ag(2)(C(12)H(8)N(2)O(4))(C(14)H(14)N(4))](n), one Ag(I) ion, lying on a twofold rotation axis, is coordinated by two N atoms from two 3,5,9,11-tetra-oxo-4,10-diaza-tetra-cyclo-[5.5.2.0(2,6).0(8,12)]tetra-dec-13-ene-4,10-diide (L) ligands in a nearly linear arrangement. The other Ag(I) ion, lying on an inversion center, is coordinated by two O atoms from two L ligands and two N atoms from two 1,4-bis-(imidazol-1-ylmeth-yl)benzene ligands in a distorted square-planar geometry. An additional Ag?Ag [3.0119?(3)?Å] inter-action links the Ag(I) ions into a chain along [010]. The two types of ligands have mirror symmetry and connect the Ag(I) ions into a layer parallel to (100).

Bis{2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium} tetra-cyanidoplatinate(II) tetra-hydrate.

Project description:The asymmetric unit of the title hydrated complex salt, (C18H14N5)2[Pt(CN)4]·4H2O, consists of one 2-[2,5-bis-(pyridin-2-yl)-1H-imidazol-4-yl]pyridinium cation, half a tetra-cyanidoplatinate(II) dianion, which is located about a crystallographic inversion center, and two water mol-ecules of crystallization. The Pt(II) atom has a square-planar coordination environment, with Pt-CCN distances of 1.992 (4) and 2.000 (4) Å. In the cation, there is an N-H⋯N hydrogen bond linking adjacent pyridinium and pyridine rings in positions 4 and 5. Despite this, the organic component is non-planar, as shown by the dihedral angles of 10.3 (2), 6.60 (19) and 15.66 (18)° between the planes of the central imidazole ring and the pyridine/pyridinium substituents in the 2-, 4- and 5-positions. In the crystal, cations and anions are linked via O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds, forming a three-dimensional network. Additional π-π, C-H⋯O and C-H⋯N contacts provide stabilization to the crystal lattice.

catena-Poly[[bis-(μ(2)-4-amino-benzene-sulfonato-κO:O)disilver]-bis-(μ(2)-4,4'-bipyridine-κN:N')].

Project description:In the title compound, [Ag(2)(C(6)H(6)NO(3)S)(2)(C(10)H(8)N(2))(2)](n), the Ag(I) atom is four-coordinated by two N atoms from two symmetry-related 4,4'-bipyridine (bipy) and two O atoms from two independent 4-amino-benzene-sulfonate (ABS) ligands. The two inter-chain Ag(I) atoms are bridged by two independent ABS ligands through weak Ag-O bonds and Ag⋯Ag attractions, forming a ladder-like chain coordination polymer [Ag(2)(ABS)(2)(bipy)(2)](n) parallel to [001], which is further linked to generate a two-dimensional structure via N-H⋯O hydrogen-bonding inter-actions.

Bis[μ-1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene-κN:N]silver(I) dinitrate dihydrate.

Project description:The reaction of 1,4-bis-(4,5-dihydro-1H-imidazol-2-yl)benzene (bib) with silver(I) nitrate in a 1:1 molar ratio generates the metallacyclic title complex, [Ag(2)(C(12)H(14)N(4))(2)](NO(3))(2)·2H(2)O, in which the bib ligand displays a cis configuration. Each bib ligand acts as a bidentate bridging ligand connecting a pair of Ag(I) ions to form a [2 + 2] metallamacrocycle in which the Ag⋯Ag distance is 6.77 (2) Å. Each Ag(I) ion has weak contacts (2.91 Å) with the nitrate anion. The uncoordinated water mol-ecules make hydrogen bonds with nitrate O atoms, forming chains. The H atoms attached to the uncoordinated nitro-gen inter-act with these chains through N-H⋯O hydrogen bonds, forming layers parallel to the (11) plane.

The crystal structure features chains linked by N-H?O hydrogen bonds.
