Spirane derivatives, which are typical molecules with axial chirality, have been mainly employed in ligand design and asymmetric synthesis (Srivastava et al, 1992;Chan et al, 1997;Ding et al, 2009;Cottam & Steel, 2009). Among them, 1,1′-spirobiindane and its analogs have also attracted much attention for their featuring C2-symmetric chiral property (Birman et al, 1999;Brewster & Prudence, 1973;Cottam & Steel, 2009).…”

Following our previous work(Yao et al, 2010), we report the structure of a bidentate flexible nitrogen ligand by coupling 1,1,-spirobiindane with nitrogen-containing heterocycles.…”

The asymmetric unit in the title compound, C33H34N2O2·H2O, consists of a V-shaped molecule and a water molecule to which it is hydrogen bonded. The angle between the mean planes of the two spiro-connected indane groups is 77.06 (5)°. The two five-membered rings of the indane groups have envelope conformations with the methylene atoms adjacent to the spiro C atom forming the flaps. They have deviations from the mean plane of the other four atoms in the rings of 0.374 (4) and 0.362 (4) Å. In the crystal, molecules are linked to form inversion dimers via O—H⋯N hydrogen bonds involving the pyridine N atoms and the solvent water molecule. The dimers are linked into a chain along the b axis by π–π stacking interactions between a pyridine ring and its centrosymmetrically related ring in an adjacent dimer. The centroid–centroid distance between the planes is 3.7756 (17) Å, the perpendicular distance is 3.4478 (11) Å and the offset is 1.539 Å.

“…In particular, flexible multidentate bridging ligands based on aliphatic spacers have received increasing attention in the field of coordination chemistry, where they have been used widely for syntheses involving transition metal cations. [4,5] Owing to the flexibility and conformational freedom inherently present in this kind of ligands, they are often very sensitive to small changes in the reaction conditions; this sensitivity can effect different coordination modes and thus generate novel complexes with unique architectures.…”

Crystals of the Schiff base compound C 22 H 24 N 4 O 4 , 1, was obtained by the reaction of indole-3-carbaldehyde with 4-(quinolin-8-yloxy)butanohydrazide and recrystallization of the product from dimethylformamide. The compound 1 has been characterized by elemental analysis, infrared (IR), 1 H-nuclear magnetic resonance (NMR), fluorescence (FL) spectra, and x-ray single crystal and powder x-ray diffraction measurements. The conformation along the bond sequence linking the indole and quinoline rings, which have a mean interplanar dihedral angle of 80.9 (4) • , is trans-trans-(-)gauche-trans-trans-trans-trans. In the crystal structure, the intermolecular N-H···N hydrogen bond links the molecules into a zigzag one-dimensional (1-D) infinite chain structure. These chains are further aggregated via π. . .π interactions into parallel layers, resulting in a supramolecular two-dimensional fragment.
