In the title compound, C18H12O2, the benzene rings are inclined to one another by 66.79 (7)°. The five-membered ring is almost planar with a maximum deviation of 0.014 (1) Å. In the crystal, the mol-ecules are linked by pairs of weak C-H⋯O interactions into centrosymmetric dimers. These dimers are linked by C-H⋯π interactions, forming a three-dimensional structure. ...[more]

Project description:In the title compound, C(25)H(23)N·CHCl(3), the dihydro-anthracene unit is bent with a dihedral angle between the benzene rings of 57.82?(8)°. The N atom of the pyrrolidine heterocycle, which has an envelope conformation with the N atom as the flap, exhibits a pronounced pyramidalization [?(C-N-C) = 328.07°], indicating an accentuated N-donor character. In the crystal, this behaviour is evident by the C-H?N hydrogen bond involving a solvent mol-ecule and the N atom. The absolute configuration at the C-atom fused positions of the pyrrolidine group were crystallographically confirmed to be S and R.

Project description:In the title compound, [Fe(C(5)H(5))(C(21)H(19)N(2)O(3))], both pyrrol-idine rings of the pyrrolizine substructure show an envelope conformation. In the ferrocenyl moiety, the unsubstituted cyclo-penta-dienyl ring is disordered over two orientations with site occupancies of 0.64?(2) and 0.36?(2). In the pyrrolizine ring, one C atom is disordered over two positions, with site occupancies of 0.71?(1) and 0.29?(1). Intra-molecular C-H?O inter-actions occur. The crystal packing is established through weak inter-molecular C-H?O and N-H?O inter-actions.

Project description:The title compound, C11H8O5, features a 'skipped' diene, an anti-bis-(epoxide) and a cyclic carbonate, all embedded in a densely functionalized [4.4.3]propellane scaffold. The crystal packing of this diepoxide is effected primarily by C-H?O hydrogen bonds, which link the mol-ecules into tapes along the b axis. Inter-tape connectivity is brought about by centrosymmetrically disposed pairs of C?O contacts [3.183?(4)?Å] between the C(?+)=O(?-) dipoles of neighbouring carbonate moieties.

Project description:The title compound, C33H35N3O5, is the product of the multicomponent condensation of 1-benzyl-4-eth-oxy-carbonyl-piperidin-3-one with 1,5-bis-(2-formyl-phen-oxy)-3-oxapentane and ammonium acetate. The mol-ecule comprises a penta-cyclic system containing the aza-14-crown-4-ether macrocycle, tetra-hydro-pyrimidine, tetra-hydro-pyridine and two benzene rings. The aza-14-crown-4-ether ring adopts a bowl conformation with a dihedral angle of 62.37?(5)° between the benzene rings. The tetra-hydro-pyrimidine ring has an envelope conformation with the chiral C atom as the flap, whereas the tetra-hydro-pyridine ring adopts a distorted chair conformation. Two amino groups are involved in intra-molecular N-H?O hydrogen bonds. In the crystal, weak C-H?O hydrogen bonds link the mol-ecules into layers parallel to the ab plane.
