(Received 25 June 2013; accepted 30 June 2013; online 6 July 2013)

The title compound,[FeCl2(C18H25N3O2)], has a distorted tetra­hedral Cl2N2 coordination of the FeII atom as a result of the constraints imposed by the 2-[2,2-bis­(4,4-dimethyl-4,5-di­hydro-1,3-oxazol-2-yl)prop­yl]pyridine ligand. The pyridine ring is almost perpendicular to the six-membered chelated ring containing the metal atom [dihedral angle between their mean planes = 88.5 (1)°].

Comment top

Metal complexes containing bis(oxazoline) ligands have been widely investigated in the field of homogeneous and asymmetric catalysis. This type of ligands could stabilize the pseudotetrahedral coordination environment of iron(II) affording to efficient ATRP catalyst. The complex Fe(box-py)Cl2 is analogous to Fe(box)Cl2, described in the literature (Ferro et al., 2007) and has been investigated in order to obtaining an improved understanding of the factors influencing efficient ATRP catalysis in iron-based systems. The title compound Fe(box-py)Cl2 (box-py = 2-[2,2-Bis-(4,4-dimethyl-4,5-dihydro-oxazol-2-yl)-propyl]-pyridine), C18H25Cl2Fe1N3O2, has been used as catalyst in the framework of still not published studies on atom transfer radical polymerization (ATRP) of styrene and methylmethacrylate. The molecular structure of Fe(box-py)Cl2 shows a distorted tetrahedral geometry, due to the constraints imposed by the ligand (N1—Fe1—N3 = 88.85 (7)°; Cl1—Fe1—Cl2 = 113.81 (3)°). The Fe—N and Fe—Cl bond distances are similar to that found for Fe(box)Cl2 and for similar saliclylaldiminato complex (O`Reilly et al., 2003). Finally, the heteroaromatic ring is almost perpendicular to the six-membered chelated ring (angle between their mean planes is equal to 88.5 (1)°) and shows the nitrogen atom pointing towards the coordination environment of the iron.

Experimental top

Fe(box-py)Cl2 was obtained by the reaction of FeCl2 with the ligand. Details for the synthesis will be reported in forthcoming work. Prismatic yellow crystals of the title complex were obtained by slow evaporation of a methylene chloride solution at room temperature.

Refinement top

All the H atoms were generated stereochemically and refined by the riding model with C–H in the range 0.95 Å–0.99 Å and Uiso(H)=1.2Ueq(C); (1.5 for H atoms of methyl groups).

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.
