4,4'-Dibromo-7,7'-dimeth-oxy-1,1'-spiro-biindane.

ABSTRACT: In the title compound, C(19)H(18)Br(2)O(2), the dihedral angle between the two benzene rings of the spiro-biindane molecule is 70.44?(8)°. In the crystal, mol-ecules are inter-connected along the c axis by C-H?O hydrogen bonds and ?-? stacking [centroid-centroid distance = 3.893?(2)?Å] inter-actions, forming an infinite chain structure. The chains are further inter-connected through another set of C-H?O hydrogen bonds, forming layers approximately parallel to the bc plane.

In the title compound, C(19)H(18)Br(2)O(2), the dihedral angle between the two benzene rings of the spiro-biindane molecule is 70.44 (8)°. In the crystal, mol-ecules are inter-connected along the c axis by C-H⋯O hydrogen bonds and π-π stacking [centroid-centroid distance = 3.893 (2) Å] inter-actions, forming an infinite chain structure. The chains are further inter-connected through another set of C-H⋯O hydrogen bonds, forming layers approximately parallel to the bc plane. ...[more]

Project description:In the title compound, C8H8Br2O2, all non-H atoms lie essentially in a common plane (r.m.s deviation of all fitted non-H atoms = 0.0330 Å). In the crystal, weak C-H⋯O hydrogen bonds connect the mol-ecules, forming chains which extend along the b-axis direction.

{4,4'-Dimeth-oxy-2,2'-[1,1'-(ethane-1,2-diyldinitrilo)diethyl-idyne]diphenolato}nickel(II) hemihydrate.

Project description:In the title complex, [Ni(C(20)H(22)N(2)O(4))]·0.5H(2)O, the Ni(II) ion is in a slightly distorted square-planar geometry involving an N(2)O(2) atom set of the tetra-dentate Schiff base ligand. The asymmetric unit contains one mol-ecule of the complex and half a water solvent mol-ecule. The solvent water mol-ecule lies on a crystallographic twofold rotation axis. An inter-molecular O-H⋯O hydrogen bond forms an R(2) (1)(4) ring motif involving a bifurcated hydrogen bond to the phenolate O atoms of the complex. In the crystal structure, mol-ecules are linked by π-π stacking inter-actions, with centroid-centroid distances in the range 3.5310 (11)-3.7905 (12) Å, forming extended chains along the b axis. In addition, there are Ni⋯Ni and Ni⋯N inter-actions [3.4404 (4)-4.1588 (4) and 3.383 (2)-3.756 (2) Å, respectively] which are shorter than the sum of the van der Waals radii of the relevant atoms. Further stabilization of the crystal structure is attained by weak inter-molecular C-H⋯O and C-H⋯π inter-actions.

Aqua-{4,4'-dibromo-6,6'-dimeth-oxy-2,2'-[ethane-1,2-diylbis(nitrilo-methyl-idyne)]diphenolato}copper(II).

Project description:The title complex, [Cu(C(18)H(16)Br(2)N(2)O(4))(H(2)O)], lies on a crystallographic mirror plane with the Cu(II) ion coordinated by two N atoms and two O atoms of a tetra-dentate Schiff base ligand and one O atom from a water ligand in a slightly distorted square-pyramidal environment. The mirror plane, which coincides with the Cu-O(water) bond, imposes disorder of the atoms of the ethyl-ene group. In the crystal structure, inter-molecular O-H?O hydrogen bonds link complex mol-ecules into extended chains along [100].

2,4-Dibromo-1,3-dimeth-oxy-5-methyl-benzene.

Project description:The title compound, C(9)H(10)Br(2)O(2), crystallizes with two mol-ecules in the asymmetric unit. The two mol-ecules are essentially planar with slight differences in the (Br)C-C-O-C(H(3)) torsion angles [-176.7 (2) and -172.8 (2)° in one mol-ecule and 174.8 (2) and 179.9 (2)° in the other]. The crystal structure consists of sheets of mol-ecules linked through Br⋯Br [3.3547 (4), 3.3703 (4) and 3.5379 (4) Å] inter-actions, which are in turn connected through π-π inter-actions with centroid-centroid distances of 3.5902 (14) and 3.5956 (14) Å.
