1,7-Diethyl-4,10-diisopropyl-tetra-cene.

ABSTRACT: The mol-ecule of the title compound, C(28)H(32), is located on a crystallographic inversion center. The ethyl groups are essentially coplanar with the tetra-cene ring, making a torsion angle of -0.4?(4)°. The isopropyl groups adopt an asymmetric conformation with their terminal methyl groups positioned on opposite sides of the tetra-cene plane [the Me-C-C-C torsion angles are -22.5?(4) and 100.9?(3)°]. In the crystal, the mol-ecules adopt an arrangement without significant ?-? inter-actions along the stacking direction (y axis).

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.

4,10-Bis(pyridin-2-ylmeth-yl)-1,7-dithia-4,10-diazo-niacyclo-dodecane bis(perchlorate).

Project description:The asymmetric unit of the title compound C(20)H(30)N(4)S(2) (+). 2ClO(4) (-) comprises one macrocyclic cation and two perchlorate anions. In the cation, one of the protonated H atoms bound to the amide N atom is involved in an intra-molecular N-H?N hydrogen bond. The O atoms in the two perchlorate anions are disordered over two sets of sites with occupancy ratios of 0.65?(3):0.35?(3) and 0.640?(15):0.360?(15).

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

Project description:The title compound, [Co(C24H28N2O6)] n , crystallizes as infinite chains related to one another by inversion centers, giving a centrosymmetric coordination polymer. The Co(II) ion, situated on a twofold rotation axis, forms a complex with the crown-4 moiety of the 3,3'-[(1,7-dioxa-4,10-di-aza-cyclo-do-decane-4,10-di-yl)bis-(meth-ylene)]dibenzoate anion. The dis-torted octahedral coordination sphere of the Co(II) ion is completed by two carboxyl-ate O atoms from two bridging intra-chain ligands. Metallomacrocyclic rings of 16 atoms are present, with each ring containing two Co(II) ions and 14 atoms from the bridging ligands. These units repeat as infinite zigzag chains along [101].

4-Diethyl-amino-3,5-diisopropyl-benzalde-hyde.

Project description:The title benzaldehyde, C(17)H(27)NO, was prepared via lithia-tion of bromoaniline and reaction with DMF. In the crystal, the molecule adopts a C2-symmetrical conformation; nevertheless, two modes of disorder are present: the orientation of the aldehyde group (occupancy ratio 0.5:0.5) and of symmetry-equivalent ethyl groups [occupancy ratio 0.595 (7):0.405 (7)]. The phenyl-ene ring and the carbonyl group are essentially coplanar [C-C-C-O torsion angle = -179.0 (4)°] but the dihedral angle between the mean planes of the phenyl-ene ring and the amino group = 67.5 (2)°. This and the long [1.414 (3) Å] aniline C-N bond indicate electronic decoupling between the carbonyl and amino groups. The angle sum of 359.9 (2)° around the N atom results from steric compression-induced rehybridization.

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.

Poly[[?(2)-1,4-bis-(imidazol-1-ylmethyl)-benzene](?(4)-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-diido)disilver(I)].

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: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].

An intra-molecular N-H?N contact occurs. There are two independent molecules in the asymmetric unit.
