Bis[(μ-1,3-diphenylpropane-1,3-dionato-O,O′:O′)dimethylthallium], [(CH₃)₂Tl(bzbz)]₂

D. Britton

The title compound, [Tl₂(CH₃)₄(C₁₅H₁₁O₂)₂], contains two five-coordinate Tl atoms. Two crystallographically independent molecules, symmetries 1 and $\overline 1$ , have essentially the same geometry except for the rotations of the phenyl rings. The Tl—O distances in the monomer chelate ring average 2.467 (15) Å. The Tl—O distances between the two monomer units average 2.78 (2) Å. The Tl—C distances average 2.123 (11) Å. The Tl atoms are not coplanar with the chelate rings. The independent molecules are related by an approximate pseudosymmetry.

Comment top

In a discussion of the structures of some dimethylthallium compounds (Chow & Britton, 1975), we reported a partial determination of the structure of the title compound, (I). The complete structure is reported here.

There are one and one-half molecules in the asymmetric unit; using the notation suggested by Zorky and co-workers (Zorky at al., 1967; Belsky et al., 1995; Zorky, 1996), the structure is in Pbca, Z = 12 (1, 1). The two independent molecules are shown in Figs. 1 and 2. Selected bond lengths and angles are given in Table 1.

The six Tl—C distances average 2.123 (11) Å. The three Tl—O distances to the non-bridging O atoms in the chelates average 2.467 (15) Å, while those to the bridging O atoms average 2.445 (4) Å; this is not a significant difference. The Tl—O distances to the bridging O average 2.78 (2) Å, significantly longer than in the chelate. The increase in distance from Tl—C to Tl—O suggests that the former are predominantly covalent while the latter have more ionic character.

The overall geometries of the two molecules are quite similar. The Tl₂O₂ ring is exactly planar in the molecule including Tl1 since this lies on a center of symmetry. The other molecule is only approximately centrosymmetric. In this case, the Tl₂O₂ ring has a dihedral angle of 7.0 (3)° at the O atoms. The central Tl₂O₄ fragment is close to planarity, although the small deviations from planarity are significant. The TlO₂ fragment in the chelate ring has a dihedral angle of 6.0 (4)° to the TlO₂ fragment in the bridging ring at Tl1; the corresponding angles at Tl2 and Tl3 are 3.9 (4) and 4.6 (4)°, respectively.

The C₃O₂ fragment in the chelate ring is approximately planar but has a dihedral angle of 23.8 (3)° to the TlO₂ fragment in the ring for Tl1; the corresponding angles for Tl2 and Tl3 are 26.9 (3) and 26.7 (4)°, respectively. Similar angles, 11.7 and 25.0°, are found in Sn(bzbz)₂ (Uchida et al., 1977). However, this bending is not universal. The same ligand forms a compound with terbium in which there are two similar chelate rings (Ward et al., 1999), but where the dihedral angles are 0.5 and 2.1°. When the phenyl groups are replaced with methyl, the chelate ring is exactly planar (Chow & Britton, 1975). Presumably the bending, when it occurs, is a consequence of the packing.

We would expect the phenyl rings to tend to be coplanar with the chelate ring in order to maximize the delocalization in the pi system. In the free ligand, these dihedral angles are 4 and 17° in one polymorph (Hollander et al., 1973), and 8 and 24° in the other (Etter et al., 1987). In our compound, the phenyl rings furthest from the bridging ring make dihedral angles to the C₃O₂ fragment of 29.2 (4), 24.3 (4) and 21.4 (4)° at Tl1, Tl2, and Tl3, respectively. The phenyl rings nearest the bridging ring make dihedral angles to the C₃O₂ fragment of 47.2 (4), 50.5 (3) and 61.1 (3)° at Tl1, Tl2, and Tl3, respectively. These larger angles are a consequence of the crowding in this molecule. This crowding also has the consequence that the Tl is only five-coordinate rather than six-coordinate, as it is when the chelating and bridging ligand is acetate, tropolonate or acetylacetonate.

The packing is shown in Fig. 3. There is a pseudosymmetric relationship bewteen the two independent molecules. It is far from exact but can be approximated as a pseudo-glide plane where the coordinates of molecule 2 are given by 0.55 - x₁, y₁-1/6, z₁. This is reflected in the intensities in the 0kl layer where the l = 6n reflection are much more intense than the l = 6n±2 reflections.
