Abstract top

In the title compound, [Fe(CH3CN)2(C14H32O4P2)2]Cl2, the FeII atom lies on a crystallographic inversion center and has a distorted trans-FeN2P4 octahedral coordination environment arising from two P,P'-bidentate 1,2-bis[bis(3-hydroxypropyl)phosphino]ethane ligands in the equatorial plane and two acetonitrile molecules in the axial positions. One of the pendant -(CH2)3OH groups of the ligand is disordered over two sets of sites in a 0.597 (5):0.403 (5) ratio. In the crystal, O-H...Cl and O-H...O hydrogen bonding helps to establish the packing.

Comment top

The bidentate phosphine 1,2-bis[di(3-hydroxypropyl)phosphino]ethane (DHPrPE) was developed as a water soluble ligand for use in making iron complexes capable of binding dinitrogen and hydrogen (Miller et al., 2002). It was found that the hydroxypropyl groups were non-innocent in reactions with iron(II), and a stable complex was isolated in which the chelating phosphine ligands are tridentate and coordinate through one of the hydroxypropyl groups in addition to both phosphines. This results in a coordinatively saturated complex where the alcohols ligands are cis to one another. The current work shows that addition of acetonitrile to this species results in the rearrangement to the trans geometry.

The stucture of the cation [Fe(DHPrPE)2(CH3CN)2]2+ in the title compound, (I), is shown in Fig. 1. The four phosphine donors from the DHPrPE ligands form a square planar arrangement around the iron atom and the two coordinated acetonitrile ligands occupy the trans axial sites to form a distorted octahedral geometry around the iron. Such trans bis acetonitrile complexes of iron(II) with bidentate phosphines are not uncommon. The first reported structure was of the DMPE analog (Barron et al. 1987). An examination of similar compounds (George et al. 1997, Martins et al. 1998, Gilbertson et al. 2007 and Edwards et al. 2006) shows there are minor variations within the primary coordination sphere of all of these complexes. The Fe—N bond distances vary from 1.895 to 1.917 Å; the Fe—P bond distances vary from 2.255 to 2.3032 Å and the P—Fe—P bite angles are between 84.0° and 85.5°. The Fe—P distances in the title compound, 2.2883 (5) and 2.3044 (5) Å, are at the high end of the expected range while the bite angle of 84.2° is at the low end of the range, indicating significant steric crowding around the iron center.

Experimental top

The title compound was prepared by dissolving 60 mg of iron(II)chloride tetrahydrate (0.30 mmole) and 200 mg of 1,2-bis[di(3-hydroxypropyl)phosphino]ethane (0.61 mmole) in 3.0 ml of methanol to give a dark purple solution. After addition of 2.0 ml of acetonitrile, the solution slowly turned orange indicating formation of the title complex. Addition of diethylether and filtration yielded 215 mg (90%) of the title compound as an orange, crystalline powder and gave a single resonance in the 31P{1H} NMR spectrum at 61.4 p.p.m.. Yellow blocks of (I) were grown by vapor diffusion of diethylether into a 3:1 methanol/acetonitrile solution of the complex.

Refinement top

One of the hydroxypropyl side chains is disordered over two postions in ratio 60/40. The disordered fragment was refined with the same displacement parameters for atoms in each disordered positions. The H atoms on the acetonitrile methyl groups and the alcohol groups except for the disordered one were located on residual density map and refined with isotropic thermal parameters and with restrictions; the average O—H distance of 0.967 Å (Allen et al. 1987) was used as a target for corresponding O—H bonds. All H atoms in –CH2 groups were positioned geometrically and refined as riding with C—H = 0.99 Å and Uiso(H)=1.2 Ueq(C).

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes)

are estimated using the full covariance matrix. The cell e.s.d.'s are taken

into account individually in the estimation of e.s.d.'s in distances, angles

and torsion angles; correlations between e.s.d.'s in cell parameters are only

used when they are defined by crystal symmetry. An approximate (isotropic)

treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
