1-Bromo-1′-(diphenylthiophosphoryl)ferrocene
The title compound, [Fe(C(5)H(4)Br)(C(17)H(14)PS)], crystallizes with two practically undistiguishable mol-ecules in the asymmetric unit, which are related by a non-space-group inversion. The ferrocene-1,1'-diyl units exhibit a regular geometry with negligible tilting and balanced Fe-ring centroid distances, and with the attached substituents assuming conformations close to ideal synclinal ecli...
متن کامل1-Bromo-2,4,6-tricyclohexylbenzene
The title compound, C(24)H(25)Br, packs efficiently in the crystal structure with no solvent-accessible voids and several inter-molecular H⋯H contacts approximating the sum of the van der Waals radii. The mol-ecule is quite crowded, with intra-molecular Br⋯H and C⋯H contacts ca 0.38 and 0.30 Å, respectively, less than the sum of the corresponding van der Waals radii. All cyclo-hexyl rings adopt...
متن کامل2-Bromo-1-phenylethanone
The title compound, C(8)H(7)BrO, is a halogenated derivative of acetophenone. The mol-ecule shows noncrystallographic C(s) symmetry. The intra-cyclic C-C-C angles cover the range 118.8 (2)-120.4 (3)°. In the crystal structure, C-H⋯O contacts connect the mol-ecules into undulating sheets perpendicular to the crystallographic c axis.

In the mol-ecule of the title compound, C(11)H(13)BrO, the adjacent C atoms are almost coplanar with the aromatic ring [maximum deviation 0.035 (3) Å]. In the crystal structure, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into chains along the b axis. A very weak C-H⋯π inter-action is also present.
متن کامل1-Bromo-3,5-diphenylbenzene
The title compound, C(18)H(13)Br, crystallizes with two crystallographically independent mol-ecules in the asymmetric unit. The C-Br bond lengths and the C-C bond lengths between the benzene rings are slightly different in the two mol-ecules. The dihedral angles between adjacent benzene rings are 26.85 (2) and 39.99 (2)° in one mol-ecule, and 29.90 (2) and 38.01 (2)° in the other. There are thr...
