Abstract: Organometallic salt[CpFe (C6H6)]2·[Ni (mnt)2] was synthesized by the metathetical reaction of [CpFe (C6H6) ]PF6 with Na2[Ni (mnt)2]. It was characterized by elementary analysis, IR and 1H NMR spectra. The structure of this compound was determined by X-ray single crystal diffraction analysis. The crystallographic data are as follows: triclinic,space group P1, α=0. 838(2) nm, b=1. 084(6)nm, c=1. 816(7) nm,α=83. 41 (4)°, β=89. 30(3)°,γ= 80. 22(3)°, Z= 2. The cations exist in two directions, which are perpendicular to each other. The anions also exist in two directions, which form a dihedral angle of 75. 4°. Conductivity measurements of the compound showed a semiconductor behavior with a conductivity of 4.1×10-5 S·cm-1 at room temperature.
