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

ABSTRACT: 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.

Project description:The title compound, 2C(4)H(12)N(2) (2+)·C(10)H(2)O(8) (4-)·6H(2)O or (pipzH(2))(2)(btc)·6H(2)O, was formed from the reaction between benzene-1,2,4,5-tetra-carboxylic acid (btcH(4)) as a proton donor and piperazine (pipz) as a proton acceptor.

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.

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, ?-? 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, ?-? 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).

Poly[[?(2)-1,3-bis-(imidazol-1-ylmeth-yl)benzene][?(2)-2,2'-dihy-droxy-1,1'-methyl-enebis(naphthalene-3-carboxyl-ato)]zinc].

Project description:In the title compound, [Zn(C(23)H(14)O(6))(C(14)H(14)N(4))](n), the Zn(II) ion is four-coordinated in a distorted tetra-hedral geometry. The 1,3-bis-(imidazol-1-ylmeth-yl)benzene and 2,2'-dihy-droxy-1,1'-methyl-enebis(naphthalene-3-carboxy-l-ate) ligands con-nect the Zn(II) ions alternately in different directions, forming a layered structure parallel to the ac plane. Topological analysis reveals that the whole structure is a (4,4) network. The layers are further assembled into a three-dimensional supra-molecular structure via C-H?O and C-H?? inter-actions.

Project description:In the title coordination polymer, [Cd(C(8)H(11)O(4))(2)(C(14)H(14)N(4))](n), the Cd atom (site symmetry 2) is six-coordin-ated by two O,O'-bidentate 4-carboxy-cyclo-hexa-necarboxyl-ate (Hchdc) ligands and two N atoms from two different 1,4-bis-(imidazol-1-ylmeth-yl)benzene (1,4-bix) mol-ecules in a very distorted cis-CdN(2)O(4) octa-hedral environment. The 1,4-bix mol-ecules act as bridging ligands that bind two Cd(II) atoms, thus forming an infinite chain propagating in [100], which is decorated by the Hchdc anions. The structure is completed by O-H?O hydrogen bonds, which link the chains together.
