چکیده
In the title mol-ecule, [Fe(C(5)H(5))(C(7)H(6)BrO)], the C atoms of the substituted ring have disparate Fe-C bond lengths compared with the unsubstituted ring. In the bromo-acetyl residue, the Br and O atoms are co-planar [the O-C-C-Br torsion angle is 5.7 (4)°] and are syn to each other. Helical supra-molecular chains along the b axis are formed in the crystal structure mediated by C-H⋯O contacts; the carbonyl-O atom is bifurcated. The chains are linked into layers by C-H⋯π(unsubstituted ring) inter-actions that stack along the a-axis direction.

Methyl 5-(2-bromoacetyl)-2-propoxybenzoate
The title compound, C(13)H(15)BrO(4), was synthesized from methyl 5-acetyl-2-hydroxy-benzoate. With the exception of the ester group and some H atoms, the molecule is planar, the average deviation from planarity being 0.086 (5) Å. The dihedral angle between the phenyl ring and the ester group is 41.6 (3)°. Adjacent mol-ecules are inter-connected by C-H⋯O bonds, generating a layered structure.

A new ferrocene derivative (1-[(4-amino) phenylethynyl]ferrocene, Fc-NH(2)) was synthesized for the first time. The ferrocene derivative molecule contained the phenylethynyl skeleton, ferrocene and amino groups with excellent electrochemical properties. The graphene/Fc-NH(2) nanocomposite was prepared by mixing graphene solution and Fc-NH(2) solution in one pot and the nanocomposite was utilize...
