(±)-trans-3-Benzoyl-bicyclo-[2.2.2]octane-2-carboxylic acid.

ABSTRACT: The title keto acid, C(16)H(18)O(3), displays significant twisting of all three ethyl-ene bridges in its bicyclo-[2.2.2]octane structure owing to steric inter-actions; the bridgehead-to-bridgehead torsion angles are 13.14?(12), 13.14?(13) and 9.37?(13)°. The compound crystallizes as centrosymmetric carboxyl dimers [O?O = 2.6513?(12)?Å and O-H?O = 178°], which have two orientations within the cell and contain no significant carboxyl disorder.

The title keto acid, C(16)H(18)O(3), displays significant twisting of all three ethyl-ene bridges in its bicyclo-[2.2.2]octane structure owing to steric inter-actions; the bridgehead-to-bridgehead torsion angles are 13.14 (12), 13.14 (13) and 9.37 (13)°. The compound crystallizes as centrosymmetric carboxyl dimers [O⋯O = 2.6513 (12) Å and O-H⋯O = 178°], which have two orientations within the cell and contain no significant carboxyl disorder. ...[more]

Project description:There are two independent but virtually identical mol-ecules of each component in the asymmetric unit of the title 1:1 adduct, C(6)H(12)N(2)·C(6)H(6)O(2). In the crystal, the constituents are connected into a supra-molecular chain along the b axis by O-H?N hydrogen bonds. Weak C-H?O bonds cross-link the chains.

1,4-Diaza-bicyclo-[2.2.2]octa-ne-trans,trans-hexa-2,4-dienedioic acid (1/1).

Project description:The title 1:1 co-crystal, C(6)H(12)N(2)·C(6)H(6)O(4), the dicarb-oxy-lic acid mol-ecule is close to planar [r.m.s. deviation from the mean plane = 0.07?(1)?Å]. In the crystal, the two mol-ecules are arranged alternately and are linked by O-H?N hydrogen bonds, leading to the formation of a chain along the [20-1] direction. The chains are assembled into a two-dimensional framework parallel to the (102) plane through weak C-H?O hydrogen bonds between the two types of mol-ecules.

1,4-Di-aza-bicyclo-[2.2.2]octane-1,4-diium bis-(3-chloro-benzoate).

Project description:In the title salt C6H14N2 (2+)·2C7H4ClO2 (-), two 3-chloro-benzoate (3CBA) anions are bridged by one diprotonated 1,4-di-aza-bicyclo-[2.2.2]octane-1,4-diium (H2DABCO(2+)) dication through N-H⋯O hydrogen bonds. In this way, a trimeric unit is generated, in which the mean planes of the two 3CBA anions are twisted with respect to each other by a dihedral angle of 59.87 (9)°. The trimeric units are linked into a three-dimensional network via weak C-H⋯O inter-actions.

Asymmetric 1,4-bis(ethynyl)bicyclo[2.2.2]octane rotators via monocarbinol functionalization. Ready access to polyrotors.

Project description:Asymmetric rotators with a 1,4-bis(ethynyl)bicyclo[2.2.2]octane (BCO) core are needed for engineering crystalline arrays of functional molecular rotors. Their synthesis uses carbinol, 2-methyl-3-butyn-2-ol, as a protecting group because of its polar character and its ability to sustain orthogonal functionalization with the further advantage of being readily removed. The synthesis in good yields of unprecedented asymmetric rotors and polyrotors demonstrates the efficiency of this strategy.

rac-(2R*,3S*,5S*,6R*,7S*,8S*)-7,8-Dichloro-bicyclo-[2.2.2]octane-2,3,5,6-tetrayl tetra-acetate.

Project description:The title compound, C(16)H(20)Cl(2)O(8), contains a central bicyclo-[2.2.2]octane skeleton with slightly twisted conformation. In this structure, the C-C bond lengths are in the range 1.525?(2)-1.552?(2)?Å. Two sides of this skeleton have cis,cis acet-oxy substituents and the Cl atoms have a trans arrangement. An extensive network of weak C-H?O interactions stabilizes the crystal structure.

1-Cyano-methyl-4-aza-1-azonia-bicyclo-[2.2.2]octane bromide dihydrate.

Project description:In the crystal structure of the title compound, C(8)H(14)N(3) (+)·Br(-)·2H(2)O, inter-molecular O-H?O and O-H?Br hydrogen bonding occurs. The water mol-ecules are connected into chains extending in the a-axis direction. The bromide anions are connected to the water mol-ecules, forming 10-membered rings. The cations are connected to the anions via weak C-H?Br inter-actions. Two carbon atoms of the cation are disordered and were refined using a split model (occupancy ratio 0.70:0.3).

catena-Poly[[chloridomercury(II)]-μ-1,4-diaza-bicyclo-[2.2.2]octane-κN:N'-[chlorido-mercury(II)]-di-μ-chlorido].

Project description:In the title coordination polymer, [Hg(2)Cl(4)(C(6)H(12)N(2))](n), each Hg(II) center within the chain is four-coordinated by one terminal Cl atom, two bridging μ(2)-Cl atoms, and one N-atom donor from a μ(2)-1,4-diaza-bicyclo-[2.2.2]octane (μ(2)-daco) ligand in a distorted tetra-hedral geometry. The daco ligand acts as an end-to-end bridging ligand and bridges adjacent Hg(II) centers, forming a chain running along [001]. Weak C-H⋯Cl hydrogen-bonding inter-actions link the chains into a three-dimensional network. Comparison of the structural differences with previous findings suggests that the space between the two N donors, as well as the skeletal rigidity in N-heterocyclic linear ligands, may play an important role in the construction of such supra-molecular networks.

Project description:In the title compound, C11H17NO4, commonly known as N-tert-but-oxy-carbonyl-5-hy-droxy-d-pipecolic acid lactone, the absolute configuration is (1R,4R) due to the enantiomeric purity of the starting material which remains unchanged during the course of the reaction. In the crystal there no inter-molecular hydrogen bonds.
