Abstract top

The title extended solid coordination compound, {[Fe(C44H40N2O4P2)(C3H7NO)2](ClO4)2·2C3H7NO}n, was crystallized unexpectedly from the reaction mixture containing the Trost ligand (1R,2R)-(+)-1,2-diaminocyclohexane-N,N'-bis(2'-diphenylphosphinobenzoyl) and Fe(ClO4)2·6H2O in a 1:1 ratio in dimethylformamide (DMF) under reflux conditions. The polymeric complex is characterized by FeII metal centers that are coordinated by two oxidized Trost ligands, each coordinated in a bidentate fashion in a square plane, along with two DMF molecules above and below the plane [average Fe-ODMF = 2.086 (4) Å], forming an overall pseudo-octahedral geometry. The Trost ligand binds adjacent FeII centers, each FeII being bound through the O atom of one of the phosphine oxides [average Fe-OPPh2 = 2.115 (4) Å] and the carbonyl O atom of the adjacent amide [average Fe-Oamide = 2.192 (3) Å]. Disorder is observed in the co-solvated solvent: there are two DMF molecules per FeII centre, which were modeled as one DMF molecule with complete occupancy and the other being modeled in two positions with equal occupancy. Disorder was also observed with one of the perchlorate anions, which was modeled in two positions with 0.75:0.25 occupancy.

Comment top

In the course of examining metal-amidato systems, we reacted the Trost ligand (1R,2R)-(+)-1,2- diaminocyclohexane-N,N'-bis(2'-diphenylphosphinobenzoyl) with Fe(ClO4)2.6H2O in order to form the tetracoordinated FeII complex using similar conditions reported by Wong (Gao et al., 1996) for the analogous RuII complex (Figure 1). Using Fe(ClO4)2.6H2O as the metal salt and DMF as the solvent, a pale brown solid was obtained which was recrystallized for x-ray analysis.

The structure of the extended cation of [[Fe(µ-(κ4-O1:O2, O1': O2' H2N2(P O)2)2(DMF)2](ClO4)2.2DMF]x is shown in Figure 2. It is noted that adventitious water and/or oxygen oxidized the phosphine moieties. Only one isomer of the product was observed; where two oxidized Trost ligands (phosphine oxides) adopt a trans-coordination geometry with respect to each other, and two DMF molecules binding to the apical sites forming an octahedral FeII complex (Figure 3). The ligands bond to FeII through the amide carbonyl O atom and the O atom of the oxidized PPh2 unit. The Fe—OPPh2 bond lengths are 2.089 (3) and 2.140 (4) Å, which are in the range of those reported (2.097 (2) - 2.132 (2) Å) for other FeII phosphine oxide complexes (e.g. Buchard et al., 2009 and Escriche et al., 2006).

The Fe-OAmide bond distances (2.187 (3) and 2.197 (3) Å) are longer than those observed in [FeII(BPGm)(O2CCH3)(CH3OH)]BPh4 (2.170 (5) Å; BPGm = bis(2-pyridylmethyl)glycinamide: Mandal et al., 1997) and significantly longer than those in Fe—ODMF complexes (2.12 Å average; Constant et al., 1971; Müller et al., 1989), including those in the title structure (Fe—ODMF: 2.084 (4) and 2.087 (4) Å). Disorder was observed solely from the co-solvated DMF molecules and one of the perchlorate anions (see Figure 3). The co-solvated DMF was modeled with one molecule at 100% occupancy and the other modeled at two positions (DMF's containing N3s and N4s) with 50:50 occupancy. Bond distances of one DMF molecule were restrained owing to unmodelable disorder. The disordered perchlorate ion (containing Cl2) was modeled in two positions with 75:25 occupancy and some of the thermal parameters were restrained to be similar to each other because of NPD's.

Experimental top

To a 100 ml sidearm flask containing a stirbar and ligand (1R,2R)-(+)-1,2- diaminocyclohexane-N,N'-bis(2'-diphenylphosphinobenzoyl) (0.1235 g, 1.787x10-4 mol) was added Fe(ClO4)2.6 H2O (0.06650 g, 1.833x10-4 mol). The sidearm had a septum placed on it and was evacuated under high vacuum and re-filled with N2 (x3) and left under an N2 atmosphere. De-oxygenated acetonitrile (dried via Innovative Technologies solvent purification system: SPS) was cannulated (25 ml) into the sidearm. The mixture was left unstirred for 4 h and then it was stirred and all solid dissolved leaving a light yellow solution. The septum on the sidearm was replaced with a reflux condenser and gas-inlet adaptor (oven dried overnight), all flushed with N2. The reaction mixture was heated to reflux in an oil bath (80–85 °C) and left to stir for 14 h. The solution was cooled to room temperature and the solution was filtered into another sidearm flask. The filtrate solvent was removed under reduced pressure leaving a resulting brown solid (mass) that was transferred to the glovebox for storage. The solid (20 mg) was dissolved in minimal DMF (dried via SPS), filtered to remove any undissolved particles, and placed in a 1 dram vial. The vial was placed in a 3 dram vial containing diethyl ether (dried via SPS) and the 3 dram vial was sealed to allow vapor diffusion crystallization to occur. After 2 days, oval crystals of the title complex precipitated and one was characterized by x-ray crystallography.

Refinement top

Owing to unmodelable disorder, the bond distances on one of the co-solvated molecules of DMF was restrained. Furthermore, one of the co-solvated DMF molecules was disordered 75:25. One of the perchlorates was disordered 50:50 and some of the thermal parameters were restrained to be similar to each other because of NPD's.

Special details top

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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.
