The reaction of cis-[FeH2(DMPE)2] (DMPE = 1,2-bis(dimethylphosphino)ethane) (1a) and trans-[FeCl2(DMPE)2] (7a) with acetonitrile, cyanocyclopropane, benzonitrile, p-bromobenzonitrile and terephthalonitrile and reaction of trans-[FeCl2(DEPE)2] (DEPE = 1,2-bis(diethylphosphino)ethane) (7b) with acetonitrile, cyanocyclopropane and benzonitrile in methanol solution resulted in a series of nitrile chloride complexes trans-[FeCl(N≡C-R)(PP)2]+ and bis-nitrile complexes trans-[Fe(N≡C-R)2(PP)2]2+ of iron. All of the complexes have been characterised spectroscopically and four bis-nitrile complexes have been characterised crystallographically. Crystals of trans-[Fe(N≡CCH3)2(DMPE)2][2PF6] (3a) are monoclinic, space group P2/c, with a = 8.697(3), b = 9.165(5), c = 20.026(5)A, β = 107.54(3)°, Z = 2 and R = 0.058 (2300 F values). Crystals of trans-[Fe(N≡CC3H5)2(DEPE)2][2BF4] (4b) are monoclinic, space group P21/n, with a = 11.146(1), b = 15.396(2), c = 11.810(2)A, β= 111.06(1)°, Z = 2 and R = 0.050 (3011 F values). Crystals of trans-[Fe(N≡CPh)2(DMPE)2][2PF6] (5a) are monoclinic, space group P21/n, with a = 11.006(2), b = 12.351(3), c = 13.650(4)A, β = 93.60(2)°, Z = 2 and R = 0.035 (2650 F values). Crystals of trans-[Fe(p-N≡CC6H4Br)2(DMPE)2][2PF6][0.5KPF6] (6a) are tetragonal, space group 14c2, with a = b = 20.015(6), c = 21.610(3) A, β = 90.00°, Z = 8 and R = 0.049 (2235 F values).
