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

ABSTRACT: 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-9,9-dimethyl-9H-fluorene.

Project description: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.

4,5-Dibromo-2,7-di-tert-butyl-9,9-dimethyl-9H-thioxanthene.

Project description:In the title compound, C(23)H(28)Br(2)S, the thioxanthene unit is twisted, showing a dihedral angle of 29.3?(5)° between the benzene rings. When projected along [001], the packing shows two types of channels. The crystal studied was a racemic twin.

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.

9,9-Dibutyl-9H-fluorene-2-carbonitrile.

Project description:The fluorene fragment of the title compound, C(22)H(25)N, is essentially planar, with an r.m.s deviation of the five-membered ring of 0.005 (2) Å. The dihedral angle between this ring and the outer benzene rings are 1.5 (2) and 0.7 (2)° while that between the benzene rings is 2.1 (2)°. The cyano group makes an angle of 0.3 (2)° with the attached benzene ring.

(9H-Carbazol-9-ylmeth-yl)diethyl-amine.

Project description:The asymmetric unit of the title compound, C(17)H(20)N(2), contains two mol-ecules, whose bond lengths and angles differ only slightly. In the crystal, neighbouring mol-ecules form pillar structures via edge-to-face ?-? stacking inter-actions [edge-to-face distances = 3.538?(3) and 3.496?(3)Å].

Di-tert-butyl 2,2'-[9H-fluorene-9,9-diylbis(p-phenyl-ene-oxy)]diacetate.

Project description:In the title mol-ecule, C(37)H(38)O(6), the non-fused C atom belonging to the five-membered ring of the fluorene system is connected to two p-phenyl-ene rings, the rings opening up the C(ar-yl)-C-C(ar-yl) angle to 113.1?(1)°. The four-atom -O-CH(2)-C(=O)-O- chain between the p-phenyl-ene ring and the tert-butyl group assumes a more regular W-shaped conformation for one substituent [O-C-C-C torsion angle = 171.9?(2)°] but a less regular W-shaped conformation for the other [torsion angle = 147.4?(2)°].

Crystal structure of 9-butyl-3-(9-butyl-9H-carbazol-3-yl)-9H-carbazole.

Project description:In the title carbazole derivative, C32H32N2, the mol-ecule resides on a crystallographic twofold axis, which runs through the central C-C bond. The carbazole ring system is almost planar, with a maximum deviation of 0.041?(1)?Å for one of the ring-junction C atoms. The crystal packing is stabilized by C-H?? inter-actions only, which form a C(7) chain-like arrangement along [110] in the unit cell.

2-(9,9-Diethyl-9H-fluoren-2-yl)-1-benzofuran.

Project description:In the title compound, C(25)H(22)O, the dihedral angle between the benzofuran and fluorene ring systems is 9.06 (6)°, and that between the two benzene rings of the fluorene system is 1.78 (12)°. Weak inter-molecular C-H⋯π inter-actions help to stabilize the crystal structure.
