Tetracarbonyl-1κ²C,3κ²C-bis[1,3(η⁵)-cyclopentadienyl]dihydroxido-2κ²O-diirontin(2 Fe—Sn) monohydrate

In the title hydrate, [Fe₂Sn(C₅H₅)₂(OH)₂(CO)₄]·H₂O, the central Sn atom is tetrahedrally coordinated by two {Cp(CO)₂Fe} fragments and two hydroxide groups. The [{Cp(CO)₂Fe}₂Sn(OH)₂] and water molecules are linked by O—H

O hydrogen bridges, giving two-dimensional arrays with 4.8² topology that stack along the c axis.

In the structure of the title compound, (I), a known material but with limited characterisation data (Nesmeyanov et al., 1966), the tin atom is surrounded by two {Cp(CO)₂Fe} fragments and two OH groups in a distorted tetrahedral arrangement (Fig. 1). The {Cp(CO)₂Fe}₂Sn unit shows experimentally equivalent Sn—Fe bond lengths of 2.534 (1) and 2.535 (1) Å, and a Fe—Sn—Fe angle of 122.8 (1) °. Compared to [{Cp(CO)₂Fe}₂SnCl₂] (Sn—Fe: 2.492 (8) Å; Fe—Sn—Fe: 128.6 (3) °), the Sn—Fe distances are around 0.05 Å longer and the Fe—Sn—Fe angle is reduced by 6° (O'Connor & Corey, 1967). Compound (I) also contains two Sn—O bonds of 2.016 (2) and 2.026 (2) Å which are close to the Sn—O distance found in [{Cp(CO)₂Fe}₃SnOH] (Fässler & Schütz, 1997). As compared to the dihydroxy derivatives (2,6-Mes₂H₃C₆)₂Sn(OH)₂ (Sn—O: 1.97 (4) Å ) (Pu et al., 2001) and (Bbt)(Titp)Sn(OH)₂ (Sn—O: 1.990 (4) and 2.005 (4) Å) ((Bbt = 2,6-{(CH(SiMe₃)₂}₂-4-{CSiMe₃}₃H₂C₆; Titp = 2,6-{2,4-(i-Pr)₂H₃C₆}H₄C₆) (Tajima et al., 2006), the Sn—O bonds in (I) are slightly enlongated. This might be due to the presence of hydrogen bonds involving both OH groups but in different types of hydrogen bridges, Fig. 2. Two hydrogen bridges are formed between the O7-water molecule as donator and the hydroxyl oxygen atoms O5ⁱⁱⁱ and O6 as acceptors. Additionally, the hydroxyl group O5–H1 forms a hydrogen bridge to the water oxygen atom O7ⁱ and the hydroxyl group O6–H2 is involved in a hydrogen bridge with the carbonyl oxygen atom O1ⁱⁱ. Consequently, a two-dimensional array is formed that comprises 8-membered O₄H₄ rings (I in Fig. 2), 12-membered Sn₂O₆H₄ rings (II), 12-membered Sn₂Fe₂C₂O₄H₂ rings (III) and 20-membered Sn₂Fe₂C₂O₈H₆ rings (IV). The interconnection of theses rings leads to a three-connected net with 4.8²topology.

Experimental top

To a solution of 3.24 g (6.2 mmol) [{Cp(CO)₂Fe}₂SnCl₂] in CH₂Cl₂ (15 ml), a solution of NaOH (2.4 g, 60 mmol) in water (9 ml) was added at 273 K. Within 3 h, yellow-orange crystals of (I) were formed at the CH₂Cl₂/H₂O interface. The precipitate was filtered, washed with water, and dried. Yield: 2.37 g (73 %). Anal.

Special details top

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