In the title molecular salt, C(10)H(15)NH(3) (+)·C(7)H(5)O(2) (-), both carboxyl O atoms act as acceptors for strong N-H⋯O inter-molecular hydrogen-bond inter-actions with the ammonium group in the cation, generating infinite chains along the b axis. A weak C-H⋯π inter-action is also present.

In the title compound, C(10)H(18)N(+)·C(2)H(3)O(2) (-), the ammonium H atoms of the cation are linked to three acetate anions via N-H⋯O hydrogen bonds, forming a chain structure extending along the b axis.

In the title compound, C(18)H(24), the adamantane cage consists of three fused cyclo-hexane rings in almost ideal chair conformations, with C-C-C angles in the range 108.0 (14)-111.1 (15)°. The phenyl and 1-adamantyl substituents adopt anti orientations with a C-C-C-C torsion angle of 177.10 (16)°. In the crystal packing, the mol-ecules are linked by weak C-H⋯π inter-actions into chains along t...

The title compound, C(11)H(17)NS, is an important inter-mediate for the synthesis of biologically active adamantlythia-zolo-oxadiazo-les. The adamantyl residue is disordered about a twofold rotation axis over two sites with site-occupation factors of 0.817 (3) and 0.183 (3). The crystal structure is stabilized by inter-molecular N-H⋯S hydrogen-bonding inter-actions.

The title compound, C(11)H(17)Br, has crystallographically imposed mirror symmetry in the solid state with mol-ecules bis-ected by mirror planes parallel to the crystallographic ac plane (five C atoms, three H atoms and the Br atom lie on the mirror plane). The asymmetric unit contains one half-mol-ecule. The crystal packing is stabilized only via weak non-specific van der Waals inter-actions.

The electronic structure and chemical bonding in donor-acceptor complexes formed by group 13 element adamantane and perfluorinated adamantane derivatives EC9 R'15 (E = B, Al; R' = H, F) with Lewis bases XR3 and XC9 H15 (X = N, P; R= H, CH3 ) have been studied using energy decomposition analysis at the BP86/TZ2P level of theory. Larger stability of complexes with perfluorinated adamantane deriva...

Topological indices are numerical parameters of a graph which characterize its topology. In this paper the PI, Szeged and Zagreb group indices of the tetrameric 1,3–adamantane are computed.

We prepared adamantane-containing amphiphiles and evaluated them using a large membrane protein complex in terms of protein solubilisation and stabilization efficacy. These agents were superior to conventional detergents, especially in terms of the membrane protein solubilisation efficiency, implying a new detergent structure-property relationship.
