Crystal structure of 5,5'-di-bromo-3,3'-di-tert-butyl-6,6'-di-methyl-biphenyl-2,2'-diol.

ABSTRACT: The whole mol-ecule of the title compound, C22H28Br2O2, is generated by twofold rotation symmetry. The dihedral angle of the biphenyl moiety is 85.05 (11)°. The hy-droxy groups show intra-molecular O-H⋯π inter-actions without any other hydrogen-bond acceptors. In the crystal, there are no other significant inter-molecular inter-actions present.

3,3'-Di-tert-butyl-5,5'-dimethoxy-biphenyl-2,2'-diol.

Project description:The title compound, C(22)H(30)O(4), displays twofold rotational symmetry. The two benzene rings are almost perpendicular to each other, forming a dihedral angle of 89.8?(6)°. In the crystal, mol-ecules are linked into an extended one-dimensional chain structure via inter-molecular O-H?O hydrogen bonds.

3,3'-Di-tert-butyl-2'-hydr-oxy-5,5',6,6'-tetra-methyl-biphenyl-2-yl benzene-sulfonate.

Project description:In the title compound, C(30)H(38)O(4)S, the hydroxyl group bonded to one phenyl ring and an O atom of the benzene-sulfonate group attached to the other phenyl ring of the biphenyl backbone of the structure are involved in an intra-molecular O-H?O hydrogen bond. The dihedral angle between the planes of the two aromatic rings of the biphenyl unit is 70.4?(2)°.

3,3'-Dibromo-5,5'-di-tert-butyl-2,2'-dimethoxy-biphen-yl.

Project description:The title compound, C(22)H(28)Br(2)O(2), crystallizes in a staggered arrangement to minimize the inter-actions of its ortho substituents, with a dihedral angle of 84.2 (3)° between the two aromatic rings. Short C-H⋯O hydrogen-bonding inter-actions between meth-oxy groups result in a one-dimensional polymeric chain of mol-ecules lying parallel to the b axis. One tert-butyl group is disordered equally over two positions.

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.

Di-tert-butyl 2,2'-(biphenyl-2,2'-diyl-dioxy)diacetate.

Project description:The title compound, C(24)H(30)O(6), does not exhibit π-π inter-actions due to the steric effect of the bulky tert-butyl groups present in the mol-ecule. The presence of these groups at the 2 and 2' positions hinders the free motion of the benzene rings relative to each other, causing them to adopt an anti-periplanar arrangement. The benzene rings are twisted by just under 50.96 (17)° with respect to each other. The carbonyl groups within the mol-ecule are directed in different directions, one towards the biphenyl group and the other away from it. The mol-ecules are linked together by C=O⋯H-C hydrogen bonds.

(Biphenyl-2,2'-di-yl)di-tert-butyl-phos-phonium trifluoro-methane-sulfonate.

Project description:To aid in the elucidation of catalytic reaction mechanism of palladacycles, we found that reaction of trifluoro-methane-sulfonic acid with a phosphapalladacycle resulted in elimination of the palladium and formation of the title phospholium salt, C20H26P(+)·CF3SO3(-). Selected geometrical parameters include P-biphenyl (av.) = 1.801?(3)?Å and P-t-Bu (av.) = 1.858?(3)?Å, and significant distortion of the tetra-hedral P-atom environment with biphen-yl-P-biphenyl = 93.93?(13)° and t-Bu-P-t-Bu = 118.82?(14)°. In the crystal, weak C-H?O inter-actions lead to channels along the c axis that are occupied by CF3SO3(-) anions.

3,3',5,5'-Tetra-bromo-2,2'-bithio-phene.

Project description:The title compound, C(8)H(2)Br(4)S(2), was prepared by bromination of 2,2'-bithio-phene with bromine. The mol-ecule is located on a crystallographic twofold rotation axis, thereby imposing equal geometry of the two thio-phene rings. Each five-membered ring is planar [maximum deviation 0.011 (9) Å] and the dihedral angle between the planes through the rings is 47.2 (4)°. The mol-ecules are arranged to minimize intramolecular contacts between the 3-3' and 5-5'-bromine atoms.

6,6'-Di-tert-butyl-2,2'-[1,2-phenyl-ene-bis(nitrilo-methyl-idyne)]diphenol.

Project description:The mol-ecule of the title Schiff base compound, C(28)H(32)N(2)O(2), has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12?(14) and 26.01?(14)°. Four intra-molecular C-H?O hydrogen bonds and two intra-molecular O-H?N hydrogen bonds stabilize the mol-ecular structure. In the crystal packing, mol-ecules are stacked along the a axis and stabilized by ?-? inter-actions [centroid-centroid distance = 3.6724?(17)?Å]. The crystal studied was found to be a non-merohedral twin, the refined ratio of twin components being 0.374?(5):0.626?(5).
