The iron(II) complexes FeX2[P(CH2CH2CH2PMe2)3] with X = CN (4), N3 (5). and NCS (6) have been prepared by metathetical reaction of FeCl2[P(CH2CH2CH2PMe2)3] (1) with the corresponding sodium pseudohalide. Treatment of the dihalo compounds FeX2[P(CH2CH2CH2PMe2)3] (X2 = Cl2 (1). Br2 (2), I2 (3)) with LiAlH4 gave the halohydro derivatives FeHX[P(CH2CH2CH2PMe2)3], where HX = HCl (7). HBr (8). and HI (9). Consistent with a cis-octahedral coordination geometry, the 31P NMR spectra of 1−9 exhibit AMX2 type splitting. The halohydro complexes 7−9 have also been studied by IR and 1H NMR spectroscopy. 57Fe Möβbauer data have been collected for compounds 1, 4, and 5.
