Comment top

After the first report of the synthesis of a [1]ferrocenophane by Osborne and Whiteley in 1975 (Osborne et al., 1975), Manners and coworkers discovered that thermal ring-opening polymerization (ROP) of dimethylsila[1]ferrocenophane yield high-molecular weight polymers (Foucher et al., 1992). This discovery was a breakthrough in the area of organometallic polymers. Recently, the field of strained sandwich compounds was reviewed by Manners (Herbert et al., 2007) and Rehahn (Bellas et al., 2007).

Over the last four years, we characterized aluminium- and gallium-bridged [1]ferrocenophanes (Schachner et al., 2005a, b), (Lund et al., 2006), [1]chromarenophanes (Lund et al., 2006), [1]vanadarenophanes (Lund et al., 2006), [1]ruthenocenophanes (Schachner et al., 2007), and [1]molybdarenophanes (Lund et al., 2007).

We published the synthesis and characterization of the first strained sandwich compound with gallium in the bridging position in 2005 (Schachner et al., 2005b) (Scheme 1). However, details of the molecular structure of the title compound could not be extracted from the single-crystal X-ray analysis; only the molecular framework was revealed with certainty from the analysis (Schachner et al., 2005b). After several attempts, we succeeded in growing single crystals of high quality that allowed a complete structural solution of the compound. The galla[1]ferrocenophane crystallizes in the monoclinic space group P2₁/c with two independent molecules in the asymmetric unit. Figure 1 depicts the two independent species. In both molecules the bond lengths around the bridging Ga atoms are very similar (Ga1a—C16a = 2.018 (3); Ga1b—C16b = 2.026 (3); Ga1a—C21a = 2.023 (3); Ga1b—C21b = 2.023 (3); Ga1a—N1a = 2.084 (3); Ga1b—N1b = 2.050 (3); Ga1a—C7a = 2.043 (3); Ga1b—C7b = 2.038 (3) Å). [1]Metallacyclophanes can only be ring-open polymerized because they are intrinsically strained. The so-called α angle in strained sandwich compounds is defined as the angle between the two planes of two π-ligands. The angle between the two least squares planes of C16 - C20 and C21 - C25 are 15.4 (2)° for molecule (Ia) and 16.4 (2)° for molecule (Ib). Both values compare well with the value of the 15.83 (19)° found for the only other known galla[1]ferrocenophane (Lund et al., 2006).

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.
