(R)-2'-Benz-yloxy-5,5',6,6',7,7',8,8'-octa-hydro-1,1'-binaphthyl-2-ol.

ABSTRACT: The mol-ecules of the title compound, C(27)H(28)O(2), exhibit axial chirality. The planes of the aromatic rings of the tetra-lin ring systems make an angle of 85.72?(11)°. The non-aromatic rings adopt distorted half-chair conformations. In one of them, two C atoms of the four-atom aliphatic chain are disordered over two sites in a 0.75?(2):0.25?(2) ratio. The substituent phenyl ring is also disordered over two positions in a 0.59?(3):0.41?(3) ratio. There are no conventional hydrogen bonds joining the mol-ecules.

The mol-ecules of the title compound, C(27)H(28)O(2), exhibit axial chirality. The planes of the aromatic rings of the tetra-lin ring systems make an angle of 85.72 (11)°. The non-aromatic rings adopt distorted half-chair conformations. In one of them, two C atoms of the four-atom aliphatic chain are disordered over two sites in a 0.75 (2):0.25 (2) ratio. The substituent phenyl ring is also disordered over two positions in a 0.59 (3):0.41 (3) ratio. There are no conventional hydrogen bonds joini ...[more]

Project description:The title compound, C(36)H(24)O(6)·CH(2)Cl(2), is a dimer of two essentially planar (r.m.s., deviations of fitted plane of 14 pyracene C atoms = 0.0539 and 0.0543 Å) tetra-cyclic pyracene frameworks (each with four methyl groups and three carbonyl groups on the peripheral carbon atoms) twisted along a central C=C bond with an angle of 50.78 (3)° at 90 K. There are notably long Csp(2)-Csp(2) bonds associated with the carbonyl groups, the longest being 1.601 (3) Å between two carbonyl C atoms. There are also intermolecular carbonyl⋯carbonyl interactions of both parallel and antiparallel types, with C⋯O distances in the range 3.041 (3) to 3.431 (2) Å. This compound is of inter-est with respect to the synthesis of fullerene fragments, such as corannulene and semibuckminsterfullerene derivatives (or 'buckybowls'), and is a side product of the previously reported oxidation reaction. Structural details, such as planarity analysis of fused rings, out-of-plane deviation of substituents, inter-molecular inter-actions, and longer than typical bond lengths, will be discussed as well as comparisons to structurally related compounds.

6,6'-Dibromo-2,2'-dihex-yloxy-1,1'-bi-naphthalene.

Project description:The title compound, C(32)H(36)Br(2)O(2), was prepared by the reaction of 6-bromo-1-(2-bromo-6-hydroxy-naphthalen-5-yl)-naphthalen-2-ol and 1-iodo-hexane. The dihedral angle between the naphthalene ring planes is 63.8?(9)° The crystal structure may be stabilized by two very weak ?-? inter-actions involving the six-membered rings, with centroid-centroid distances of 4.012?(4) and 4.010?(4)?Å. The crystal studied was an inversion twin.

5,5'-Bis(benz-yloxy)-2,2'-[hydrazine-diylidenebis(methanylyl-idene)]diphenol.

Project description:The title azine mol-ecule, C28H24N2O4, lies about a center of inversion. The dihedral angle between the phenyl ring and the hy-droxy-substituted ring is 70.3?(5)°. The phenolic O-H group forms an intra-molecular hydrogen bond to the azine N atom.

1,1'-Di-tert-butyl-2,2',3,3',4,4',5,5'-octa-ethyl-1,1'-bis-tannole.

Project description:The title compound, [Sn(2)(C(4)H(9))(2)(C(12)H(20))(2)], has two 1-stannacyclo-penta-diene skeletons related by inversion symmetry located at the mid-point of the Sn-Sn bond [2.7682 (2) Å]. Thus, the asymmetric unit comprises one half-mol-ecule. The planarity of the stannacyclo-penta-diene ring is illustrated by the dihedral angle of 0.3 (1)°, defined by the C(4) and C-Sn-C planes. To avoid steric repulsion, the two stannole rings are oriented in an anti fashion through the Sn-Sn bond. These structural features are similar to those of other bis-tannoles.

Diammonium 1,1',3,3'-tetra-methyl-2,2',4,4',6,6'-hexa-oxoperhydro-5,5'-bipyrimidine-5,5'-diide monohydrate.

Project description:In the title hydrated salt, 2NH(4) (+)·C(12)H(12)N(4)O(6) (2-)·H(2)O, the two hexa-hydro-pyrimidine rings in the dianion are inclined to one another at a dihedral angle of 62.76?(5)°. In the crystal structure, the anions and water mol-ecules are linked into sheets parallel to the bc plane by inter-molecular O-H?O hydrogen bonds and sustained by C-H?O contacts. The linking of the anions and water mol-ecules with the cations by N-H?O hydrogen bonds creates a three-dimensional extended network. The crystal structure is further stabilized by very weak C-H?? inter-actions.

31-Benz-yloxy-5,11,17,23,29-penta-tert-butyl-calix[5]arene-32,33,34,35-tetra-ol.

Project description:The title compound, C62H76O5, known to be one of the most versatile synthetic precursors/inter-mediates of calix[5]arene derivatives, adopts an approximate Cs -symmetric cone-in conformation. The aryl-oxybenzyl ring is tilted in such a way that the p-tert-butyl group fills the macrocycle cavity, while the benzyl group moves away from the cavity axis. In the crystal, this conformational arrangement is secured by intra- and inter-molecular O-H?O hydrogen bonds forming inversion dimers. Four tert-butyl groups are disordered over two orientations, with occupancy ratios of 0.745?(6):0.255?(6), 0.837?(5):0.163?(5), 0.850?(5):0.150?(5) and 0.845?(8):0.155?(8).

Project description:In the title compound, C(14)H(19)N(3)O(4), the perhydro-pyran ring adopts a chair conformation. An intra-molecular C-H?O hydrogen bond generates an S(6) ring motif. In the crystal packing, mol-ecules are linked by O-H?O hydrogen bonds, forming infinite chains along [100].

Project description:In the crystal structure, the title compound, C(24)H(22)O(8), lies on a twofold rotation axis and the asymmetric unit comprises one half-mol-ecule.

No classical hydrogen bonds are found in the sturcture; only a weak C-H?? inter-action and short intra-molecular O?O contacts [2.683?(2)-2.701?(2)?Å] are observed.

Project description:The title compound, C(28)H(33)I·CHCl(3), forms dimers through C-I?? inter-actions. The crystal structure is consolidated by the presence of C-H?? inter-actions between the chloro-form solvent and the main mol-ecule.
