In the title compound, [Fe(L)₂Cl(H₂O)]·0.5CH₃CN, (HL is 3-ethoxy-2-hydroxy-benzaldehyde, C₉H₁₀O₃), there are two independent complex molecules and one acetonitrile solvent molecule in the asymmetric unit. In each complex molecule, the Fe^III ion has a distorted O₅Cl octahedral coordination environment defined by two bidentate 2-ethoxy-6-formylphenolato ligands, one Cl atom and one water molecule. In the crystal, O—H⋯O hydrogen bonds link the two independent molecules to form a dimer. The solvent molecule is linked to the complex molecule by a weak C—H⋯O hydrogen bond. Further weak C—H⋯O interactions along with weak C—H⋯Cl hydrogen bonds link the components into chains parallel to [001].

Keywords: crystal structure; solvothermal synthesis; Fe(III) complex; dimer; hydrogen bonding..

1. Chemical context

Metal complexes containing the 2-hydroxy-benzaldehyde ramification are one of the most fundamental chelating systems in coordination chemistry. Their interesting chemical and physical properties and their wide-ranging applications in numerous scientific areas have been explored widely (Han 2008 ; Ghelenji et al., 2011 ; Kia et al., 2010 ; Zhang et al., 2013 , 2014a ,b ; Zhao et al., 2014 ). During the last few years, we have investigated the chemistry of 3d metal complexes of 2-hydroxy-benzaldehyde ramification ligands with the aim of preparing mono- and heterometallic polynuclear clusters or polymers (Zhang et al., 2011 , 2013, 2014a,b; Zhao et al., 2014).

Recently, we have investigated the coordination behavior of the tridentate 2-hydroxy-benzaldehyde ramification ligand 3-ethoxy-2-hydroxy-benzaldehyde and reported two heterometallic polymers [ZnNa(ehbd)₂(N₃)]_n and [Cu₃Na₂(ehbd)₂(N₃)₆]_n (ehbd is the 2-hydroxy-3-ethoxy-benzaldehyde anion) (Zhang et al., 2014b) and a cubane cluster [Ni₄(μ₃-OMe)₄(heb)₄(MeOH)_1.05(H₂O)_2.95] (heb is the 2-hydroxy-3-ethoxy-benzaldehyde anion) (Zhang et al., 2011). The polymers [ZnNa(ehbd)₂(N₃)]_n and [Cu₃Na₂(ehbd)₂(N₃)₆]_n were prepared by room-temperature synthesis and the cubane cluster [Ni₄(μ₃-OMe)₄(heb)₄(MeOH)_1.05(H₂O)_2.95] was prepared by solvothermal synthesis. Those complexes display dominant ferromagnetic interactions between metal ions.

The title compound, [Fe(L)₂Cl(H₂O)]·0.5CH₃CN (HL = C₉H₁₀O₃), was prepared similarly to the cubane cluster [Ni₄(μ₃-OMe)₄(heb)₄(MeOH)_1.05(H₂O)_2.95] (Zhang et al., 2011) except that Ni(ClO₄)·6H₂O was replaced by FeCl₃·6H₂O in an attempt to prepare a cubane-type iron cluster. The crystals obtained, however, were those of the title mononuclear Fe^III complex.

2. Structural commentary

The asymmetric unit of the title compound consists of two neutral [Fe(L)₂Cl(H₂O)] molecules and a acetonitrile solvent molecule. One of the independent molecules is shown in Fig. 1. Each Fe^III ion is coordinated by four O atoms from two different L⁻ ligands, one Cl⁻ ion and one terminal water molecule, forming a distorted octahedral geometry. The Fe—O bond lengths are in the range 1.909 (2)–2.157 (2) Å (Table 1), while the Fe—Cl distances are 2.299 (1) and 2.301 (1) Å. The trans-angles at the Fe^III atom lie in the range 169.4 (1)–171.4 (1)°, the cis-angles vary from 81.6 (1) to 99.9 (1)°. The L⁻ ligand displays a μ₁:κ¹:κ¹ coordination mode, which is the same as that of [Ni₄(μ₃-OMe)₄(heb)₄(MeOH)_1.05(H₂O)_2.95] (Zhang et al., 2011) but the coordination mode is different from the that in [Cu₃Na₂(ehbd)₂(N₃)₆]_n (Zhang et al., 2014b) in which the ehbd⁻ ligand displays a pentadentate μ₃:κ²:κ²:κ¹ coordination mode.

3. Supramolecular features

In the crystal, O—H⋯O hydrogen bonds link the two independent molecules to form a dimer (Table 2, Fig. 2). All –OH group H atoms act as donors for two acceptor-O atoms, forming R₁²(5) and R₂²(6) graph-set motifs. A π–π interaction within the dimer with a Cg1⋯Cg2 distance of 3.575 (1)Å is observed, where Cg1 and Cg2 are the centroids defined by ring atoms C1–C6 and C19–C24, respectively. The solvent molecule is linked to the complex molecule by a weak C—H⋯O hydrogen bond. Further weak C—H⋯O interaction along with weak C—H⋯Cl hydrogen bonds link the components into chains parallel to [001] (Fig. 3).

4. Synthesis and crystallization

A mixture of FeCl₃·6H₂O (0.135 g, 0.5 mmol), 3-ethoxy-2-hydroxy-benzaldehyde (0.168 g, 1 mmol), methanol (5 mL) and acetonitrile (5 mL), with a pH adjusted to 7.5 by addition of triethylamine, was poured into a Teflon-lined autoclave (15 mL) and then heated at 413K for 3 days. Black crystals of the title compound were collected by filtration, washed with methanol and dried in air. Phase pure crystals were obtained by manual separation (yield: 124 mg, ca 54% based on Fe).

5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 3. All H atoms bonded to C atoms were positioned geometrically and refined as riding atoms, with C—H distances of 0.93 (aromatic), 0.96 (CH₂) or 0.97 Å (CH₃) with U_iso(H) = 1.2U_eq(C) or 1.5U_eq(C_methyl). H atoms bonded to O atoms were included with O—H = 0.84–0.85 Å and with U_iso(H) = 1.5U_eq(O).

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.
