Project description:The title compound, C(28)H(30)N(2), is a symmetrical 2:2 product from the condensation of indole and cyclo-hexa-none. It is the only reported 5,11-dihydro-indolo[3,2-b]carbazole compound in which the spiro atoms are quaternary C atoms. Crystals were grown by vapor diffusion in a three-zone electric furnace. The mol-ecule resides on a crystallographic inversion center. The cyclo-hexyl rings are in a slightly distorted chair conformation, whereas the indole units and the spiro-carbons are coplanar within 0.014 Å.
Project description:The title compound TNDFIW, C(8)H(8)N(10)O(10), is a caged heterocycle substituted with four nitro and two formyl groups. It is related to the hexa-azaisowurtzitane family of high-density high-energy polycyclic cage compounds. Four nitro groups are appended to the four N atoms of the two five-membered rings, while the other two formyl groups are attached to the two N atoms of the six-membered ring, which adopts a boat conformation. The compound has a cage structure which is constructed from one six-membered and two five-membered rings which are closed by a C-C bond, thus creating two seven-membered rings. There are a number of close intermolecular contacts [O⋯O = 2.827 (5), 2.853 (4) and 2.891 (5) Å; O⋯N = 2.746 (2) and 2.895 (2) Å] The calculated density of TNDFIW is 1.891 Mg m(-3).
Project description:The title salt, [CoBr(C11H27N5)]Br2·2H2O, contains a complex cation with mirror symmetry and two Br(-) counter-anions that are likewise located on the mirror plane. The central Co(III) atom of the complex cation has one Br(-) ion in an axial position, one N atom of the penta-dentate macrocyclic ligand in the other axial position and four N atoms of the ligand in equatorial positions, defining a distorted octa-hedral coordination geometry. The macrocyclic ligand is coordinated to the Co(III) atom within a 5, 6, 5 arrangement of chelate rings in the equatorial plane of the four N atoms. Due to symmetry, the configuration of the chiral N atoms is 1RS, 4SR, 10RS, 13SR. In the crystal, N-H⋯Br, O-H⋯Br and N-H⋯O hydrogen bonds between the complex cation, anions and lattice water mol-ecules generate a three-dimensional network.
Project description:The title compound, C(7)H(7)N(11)O(11) (PNMFIW), is a caged heterocycle substituted with five nitro and one formyl groups. It is related to the hexa-azaisowurtzitane family of high-density high-energy polycyclic cage compounds. Four nitro groups are appended to the four N atoms of the two five-membered rings, while a nitro group and a formyl are attached to the two N atoms of the six-membered ring.
Project description:In the title compound, C(14)H(18)ClNS, the 2,3-dihydro-1,3-thia-zole ring adopts an envelope with the S,N-bound C atom at the flap and the cyclo-hexane ring adopts a chair conformation.

Project description:In the title compound, C(16)H(22)ClNS, the nine-membered 2,3-dihydro-1,3-benzothia-zole ring system is essentially planar, with a maximum deviation of 0.025 (2) Å for the N atom. Its plane is almost perpendicular to the main plane of the substituted cyclo-hexane ring, which adopts a chair conformation. In the crystal, the molecules are linked by C-H⋯π inter-actions.
