2,7-Dibromo-9,9-dimethyl-9H-fluorene.

ABSTRACT: The title mol-ecule, C(15)H(15)Br(2), has crystallographic m2m site symmetry. As a result, all atoms, except for those of the methyl groups, are exactly coplanar. In the crystal structure, there are weak ?-? inter-actions with a centroid-centroid distance of 3.8409?(15)?Å between symmetry-related mol-ecules, which stack along the c axis.

The title mol-ecule, C(15)H(15)Br(2), has crystallographic m2m site symmetry. As a result, all atoms, except for those of the methyl groups, are exactly coplanar. In the crystal structure, there are weak π-π inter-actions with a centroid-centroid distance of 3.8409 (15) Å between symmetry-related mol-ecules, which stack along the c axis. ...[more]

Project description:In the crystal of the title compound, C(25)H(20)Br(2)N(2) (2+)·2ClO(4) (-), inter-molecular N-H?O and C-H?O hydrogen bonds, along with C-H?? inter-actions, stabilize the crystal structure.

N-(7-Bromo-9-butyl-9H-carbazol-2-yl)-9,9-diethyl-N,N,N-triphenyl-9H-fluorene-2,7-diamine.

Project description:In the title mol-ecule, C(51)H(46)BrN(3), the central fluorene residue is planar (r.m.s. deviation = 0.0203 Å), as is the carbazole system (r.m.s. deviation = 0.0154 Å), and these groups are almost orthogonal [dihedral angle = 79.72 (3)°]. The three-dimensional architecture is consolidated by C-H⋯π inter-actions. The butyl substituent is disordered with two sites resolved for the terminal propyl atoms; the major component had a site-occupancy factor of 0.686 (3).

2,7-Dibromo-9-octyl-9H-carbazole.

Project description:In the crystal structure of the title compound, C(20)H(23)Br(2)N, the octyl chains are extended in an anti conformation and form a segregating bilayer, isolating rows of carbazole units. The carbazole moieties are engaged in offset ?-? inter-actions; the smallest centroid-to-centroid distance is 4.2822?(11)?Å. This offset packing motif allows the methyl-ene group attached directly to the N atom to be involved in two short C-H?? inter-actions (H?centroid distances = 2.96 and 2.99?Å) with an adjacent carbazole. One of the Br atoms also participates in a short contact [3.5475?(3)?Å] with a symmetry-related (-x, 1 - y, -z) Br atom. This value is significantly smaller than the sum of the van der Waals radii for bromine (3.70?Å).

2,7-Dibromo-9,9-bis-[(pyridin-1-ium-4-yl)meth-yl]fluorene dinitrate.

Project description:In the title compound, C(25)H(20)Br(2)N(2) (2+)·2NO(3) (-), the cation lies on a twofold rotation axis which imposes disorder of the dibromo-fluorene unit. In addition, the unique nitrate anion is disordered over two general sites of equal occupancy. The crystal structure is stabilized by inter-molecular N-H?O hydrogen bonds.

9,9-Dioctyl-2,7-bis-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolan-2-yl)-9H-fluorene.

Project description:In the title mol-ecule, C(41)H(64)B(2)O(4), the fluorene unit is essentially planar and the two octyl chains attached to the central C atom inhibit the mol-ecule from engaging in inter-molecular aromatic inter-actions. One of the octyl chains adopts a fully extended conformation, whereas the second incorporates a single gauche conformation. Of the two pinacolatoboronate groups attached at the 2,7-positions, one is partly disordered; one ring C atom and all four methyl groups are disordered equally over two positions.

2,2'-(9,9-Dioctyl-9H-fluorene-2,7-di-yl)bis-(4,4,5,5-tetra-methyl-1,3,2-dioxaborolane).

Project description:In the title compound, C(41)H(64)B(2)O(4), one of the five-membered rings has an envelope conformation, while the other, which may be affected by disorder, is nearly coplanar with the fluorene ring. The dihedral angle between the fluorene and dioxaborolane rings is 2.29?(1)°. Two of the methyl groups are disordered over two orientations in 0.67?(3):0.33?(3) and 0.568?(10):0.432?(10) ratios.

The cyano group makes an angle of 0.3?(2)° with the attached benzene ring.

An unusual case of OD-allotwinning: 9,9?-(2,5-dibromo-1,4-phenylene)bis[9H-carbazole]

Project description:The title compound crystallizes as allotwins made up of two OD-polytypes with a maximum degree of order. 9,9?-(2,5-Dibromo-1,4-phenylene)bis[9H-carbazole] (1) crystallizes as a category I order–disorder (OD) structure composed of non-polar layers of one kind with B2/m(1)1 layer symmetry. The crystals are made up of the two polytypes with a maximum degree of order (MDO). The monoclinic MDO1 polytype (B21/d) possesses an orthorhombic B-centered lattice and appears in two orientations, which are related by reflection at (100). The orthorhombic MDO2 polytype (F2dd) has a doubled b-axis and appears in two orientations, which are related by inversion. The crystal structures of both polytypes were determined in a concurrent refinement. The MDO1:MDO2 ratio is 69:31.
