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

ABSTRACT: 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.

Project description:In the title binaphthyl compound, C34H24Cl2O2, the dihedral angle between the two naphthyl ring systems (r.m.s. deviations = 0.016 and 0.035 Å) is 76.33 (8)°.

The dihedral angle between the planes of the two chloro-phenyl rings is 27.66 (16)°. In the crystal, C-H⋯O hydrogen bonds link mol-ecules into chains propagating along [1-10]. The chains are linked by C-H⋯π inter-actions, forming a three-dimensional framework.

Project description:In the title compound, C(12)H(18)N(4)O(2), unlike other unconjugated disubstituted biimidazole derivatives reported so far, the two imidazole rings in a trans conformation exhibit a large planar rotation angle of 51.27?(4)°, and consist of half-mol-ecule asymmetric units related by a twofold rotation. The mol-ecules are linked into a three-dimensional framework with a parallel laminated construction via O-H?N and C-H?O inter-actions.

3,3'-(2,2'-Bi-1H-imidazole-1,1'-di-yl)dipropanamide.

Project description:In the title compound, C(12)H(16)N(6)O(2), the two imidazole rings are coplanar as a center of inversion exists midway along the C-C bond joining the two rings. In the crystal, inter-molecular N-H?O, N-H?N and C-H?O hydrogen bonds link adjacent mol-ecules into a two-dimensional layer structure parallel to (001).

(2R,2'S)-2,2'-Bi-piperidine-1,1'-diium dibromide.

Project description:The title compound, C10H22N2 (2+)·2Br(-), was synthesized via reduction of 2,2'-dipyridyl with Ni-Al alloy/KOH, followed by separation of diastereoisomers (meso and rac) by recrystallization from ethanol. Although the two bridging C atoms are optically active, these two chiral centers adopt an (S,R) configuration; thus, the title compound contains an achiral meso form of 2,2'-bi-piperidine. Both of the piperidinium rings adopt chair conformations, and the two N atoms are trans to each other; an inversion center is located in the mid-point of the central C-C bond. The conformation of the organic moiety resembles that of 1,1'-bi(cyclo-hexa-ne). The organic di-ammonium cations are linked to each other through hydrogen bonding with bromide counter-ions, each of which forms two hydrogen bonds (N-H?Br) with two adjacent organic cations, thus linking the latter together in sheets parallel to (100).

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

Project description: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 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.

Project description:The title compound, C(30)H(26)O(4), is a dimer of 6,6'-dimethyl-dibenzo[d,f][1,3]dioxepine linked by formation of a C-C bond in the para position with respect to one O atom.

The seven-membered ring exhibits a twisted conformation.
