1-Bromo-2-chloro-4,5-dimethoxybenzene
The mol-ecule of the title compound, C(8)H(8)BrClO(2), sits on a crystallographic inversion centre, which ensures that the halogen sites are disordered, with exactly 50% Br and 50% Cl at each halogen site. The inversion renders the two meth-oxy groups equivalent. These groups lie almost in the plane of the aromatic ring system, making dihedral angles of 8.8 (4)° to the ring.
متن کامل2-Bromo-4-chloro-6-[(1-phenylethyl)iminomethyl]phenol
The title compound, C(15)H(13)BrClNO, is a Schiff base derived from the condensation of equimolar quanti-ties of 3-bromo-5-chloro-salicylaldehyde and 1-phenyl-ethanamine. The structure displays a trans configuration with respect to the imine C=N double bond. The N atom is also involved in an intra-molecular O-H-N hydrogen bond, which stabilizes the configuration of the compound.

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 کاملAcetylferrocene–2-chloro-1-ferrocenylethanone (1/1)
In the title co-crystal, [Fe(C(5)H(5))(C(7)H(6)ClO)][Fe(C(5)H(5))(C(7)H(7)O)], both substituted ferrocene mol-ecules show the expected sandwich structure. The crystal packing exhibits weak inter-molecular Cl⋯Cl contacts of 3.279 (4) Å, π-π inter-actions between the substituted Cp rings of two neighbouring 2-chloro-1-ferrocenyl-ethanone mol-ecules [centroid-centroid distance = 3.534 (3) Å], and ...
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...
