ABSTRACT: In the title complex, [Ag(2)(C(12)H(8)N(2)O(4))(C(10)H(8)N(2))(2)]·2H(2)O, the Ag(I) ion is three-coordinated by two N atoms from a chelating 2,2'-bipyridine ligand and one N atom from an imide ligand in a Y-shaped fashion. The imide ligand and the complex lie on a twofold rotation axis. The ligand bridges two Ag(I) ions, forming a dinuclear complex. In the crystal, O-H?O hydrogen bonds link the lattice water mol-ecules and the complex mol-ecules into a ribbon-like structure along [001]. ?-? inter-actions are observed between the pyridine rings [centroid-centroid distance = 3.8289?(14)?Å].

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).

Project description:The title tetrone compound, C32H22N2O4S· 0.5C8H10, is the major product (50% yield) of an attempted Diels-Alder reaction of 2-(?-styr-yl)thio-phene with N-phenyl-male-imide (2 equivalents) in toluene. Recrystallization of the resulting powder from p-xylene gave the title hemisolvate; the p-xylene mol-ecule is located about an inversion center. In the crystal, the primary tetrone contacts are between a carbonyl O atom and the four flagpole H atoms of the bi-cyclo-[2.2.2]octene core, forming chains along [001].

Bis(dimethyl-ammonium) 3,3'-dicarb-oxy-5,5'-(5,7,12,14-tetra-oxo-6,13-diaza-tetra-cyclo-[6.6.2.0(4,16).0(11,15)]hexa-deca-1,3,8,10,15-penta-ene-6,13-di-yl)dibenzoate dihydrate.

Project description:The title compound, 2C(2)H(8)N(+)·C(30)H(12)N(2)O(12) (2-)·2H(2)O, comprises dimethyl-ammonium cations, 3,3'-dicarb-oxy-5,5'-(5,7,12,14-tetra-oxo-6,13-diaza-tetra-cyclo-[6.6.2.0(4,16).0(11,15)]hexa-deca-1,3,8,10,15-penta-ene-6,13-di-yl)dibenzoate dianions and water mol-ecules. The dianion is situated on a crystallographic inversion centre. Two very strong symmetry-restricted O⋯H⋯O hydrogen bonds are present which are situated about the crystallographic inversion centres. In one of these hydrogen bonds, the H atom is situated at its centre, while in the other one the H atom is disordered about its centre. Both H atoms are involved in the chain-like C(2) (2)(16) motif, and not in a more common motif R(2) (2)(8) that is composed of a pair of hydrogen carboxyl-ates with the H atoms situated about the centre between the pair of O atoms. In the crystal, inter-action of these hydrogen bonds results in formation of anionic layers of dianions parallel to (-111). The water mol-ecules donate their H atoms to one of two of the carboxyl-ate O atoms, forming strong hydrogen bonds. The dimethyl-ammonium donates a bifurcated hydrogen bond to an oxo group of the dianion, forming weak hydrogen bonds. All the hydrogen bonds form a three-dimensional hydrogen-bonded network.

2,2'-[4,10-Bis(carb-oxy-meth-yl)-4,10-diaza-1,7-diazo-niacyclo-dodecane-1,7-di-yl]diacetate dihydrate.

Project description:In the title compound, C(16)H(28)N(4)O(8)·2H(2)O, the 12-membered macrocycle has twofold crystallographic symmetry and the asymmetric unit comprises one half-mol-ecule. The four carbox-yl/carboxyl-ate groups reside on the same side of the macrocycle. The mol-ecule is a double zwitterion with two of the carb-oxy-lic acid H atoms transferred to the two N atoms on the opposite sides of the macrocycle, resulting in both N atoms having positive charges and leaving the two resulting carboxyl-ate groups with negative charges. The two remaining carb-oxy-lic acid groups and the carboxyl-ate groups form O-H⋯O hydrogen bonds with the crystal water mol-ecules. The H atoms bound to the N atoms within the macrocyle are engaged in two equivalent hydrogen bonds with the adjacent N atoms.

The terminal ethyl group of the ester group is disordered over two sets of sites, with a site-occupancy ratio of 0.587?(11):0.413?(11).

catena-Poly[zinc-?(3)-{3,3'-[(1,7-dioxa-4,10-diaza-cyclo-dodecane-4,10-di-yl)bis-(methyl-ene)]dibenzoato}].

Project description:The Zn(II) ion in the title compound, [Zn(C(24)H(28)N(2)O(6))](n), is located on a twofold rotation axis and is at the midpoint of a crown-4 moiety of 3,3'-[(1,7-dioxa-4,10-diaza-cyclo-dodecane-4,10-di-yl)bis-(methyl-ene)]dibenzoate anion. It is octahedrally coordinated by two N atoms and two O atoms of the crown moiety from one ligand and two carboxyl-ate O atoms from two bridging intra-chain ligands. Metallomacrocyclic rings are identified in the structure. The metallomacrocycle contains two Zn(II) ions and 14 atoms from the bridging ligands. Repetition of these units gives rise to an infinite zigzag chain along [101]. C-H?O hydrogen bonds occur.

4,4'-Bipyridine-1,1'-diium 2,3,5,6-tetra-bromo-terephthalate dihydrate.

Project description:The title compound, C(10)H(10)N(2) (2+)·C(8)Br(4)O(4) (2-)·2H(2)O, consists of a tetra-bromo-terephthalate dianion, a 4,4'-bipyridinium dication and two solvent water mol-ecules. Crystallographic inversion centers are situated at the center of the aromatic ring of the dianion as well as at the midpoint of the carbon-carbon bond connecting the pyridine rings in the dication. In the crystal, inter-molecular N-H?O hydrogen-bonding inter-actions between tetra-bromo-terephthalate dianions and protonated 4,4'-bipyridinium dications result in the formation of a chain-like structure. Further O-H?O hydrogen bonds between carboxyl-ate O atoms and water mol-ecules lead to the formation of a two-dimensional network in the crystal structure.
