Graphical Abstract
Neue Ringe: Die 1:2-Reaktion von Eisennitrat mit Benzilsäure Ph2C(OH)COOH in Methanol bei pH≈4.0 führt zu einem neuen Mitglied der Klasse molekularer Eisen-Ringsysteme („ferric wheels“) mit verbrückender Carboxylatobis(alkoxo)-Einheit. Die Molekülstruktur von [{Fe(OMe)2[Ph2C(OH)COO]}12] (siehe Bild) besteht aus einem zentrosymmetrischen, ca. 11 Å großen Ring aus zwölf nahezu coplanaren FeIII-Atomen, der von 24 μ2-Methoxyliganden und zwölf 1,3-verbrückenden Carboxylatliganden zusammengehalten wird. Das Mößbauer-Spektrum und Messungen der magnetischen Suszeptibilität werden vorgestellt.

- 17 Crystal data for 1: crystal dimensions 0.15×0.30×0.60 mm, monoclinic, space group P21/c, a=21.14(1), b=27.16(1), c=19.274(9) Å, β=104.99(1)°, V=10 689(1) Å3, Z=2, ρcalcd=1.321 g cm−3, 2θmax=43.8°, MoKα (λ=0.710730 Å), θ-2θ scan, T=298 K, 13 445 measured reflections, 12 909 independent reflections (Rint=0.0268), 12 391 reflections included in the refinement. Lorentz, polarization corrections were applied, μ=0.867 mm−1, (Δ/σ)=0.095, 1262 parameters refined, R1=0.0624 (for 8482 reflections with I>2σ(I)), wR2=0.1453 (on F 2). Max./min. residual peaks in the final difference map 0.619/−0.414 e Å−3. A crystal of 1 was mounted in a glass capillary with drops of mother liquor because of its sensitivity to air exposure. The structure was solved by direct methods using SHELXS-86 and refined by full-matrix least-squares techniques on F 2 using SHELXL-93. All non-hydrogen atoms were refined anisotropically, except for the solvent molecules, which were refined isotropically. All hydrogen atoms were introduced at calculated positions as riding on bonded atoms. CCDC-180394 (1) contains the supplementary crystallographic data for this paper.
