Abstract

The carbonyl cluster compound [GeRu6(CO)18HI] is unique in regard to its structure and bonding with a GeRu6 cluster core, a planar GeRu4HI unit, extensive multi‐center bonding, and an aromatic ring current similar to benzene (9‐10 nA T−1). The open‐shell cluster core is a Ge‐centered five‐membered Ru4(Ru2) ring with CO ligands and an additional H and I atom, each bridging two Ru atoms on opposite sides of the cluster core. The compound is prepared at 130 °C in a weakly‐coordinating ionic liquid. [ABSTRACT FROM AUTHOR]

Abstract

The halogenido stannates(II) [BMIm][Sn$_{3}$Cl$_{7}$] and [BMIm][Sn$_{4}$4Br$_{9}$] are obtained by ionic-liquid-based synthesis with SnX$_{2}$ and [BMIm]X (X=Cl, Br; [BMIm]=1-butyl-3-methylimidazolium) near room temperature (45–50 °C). Both form colorless, moisture-sensitive crystals and exhibit layered anionic networks. [BMIm][Sn$_{3}$3Cl$_{7}$7] contains “horseshoe”-like $_{∞}$$^{1}$(SnCl$_{171}$Cl$_{2/2}$) chains that are linked via [SnCl$_{3}$]− anions to $_{∞}$$^{2}$[Sn$_{3}$Cl$_{7}$]− zigzag-planes. [BMIm][Sn$_{4}$Br$_{9}$] contains a complex $_{∞}$$^{2}$[Sn$_{4}$Br$_{9}$]− network with altogether four different crystallographic Sn$_{2+}$ sites and different coordination. For comparison with these complex halogenido stannates(II), PbCl$_{2}$/PbBr$_{2}$ are reacted with similar conditions, which, however, only results in [BMIm][PbCl$_{3}$] containing $_{∞}$$^{1}$[PbCl$_{3}$]− chains. Beside the crystal structures, the thermal and optical properties are examined and feature certain emission of visible light for all title compounds at room temperature. Whereas the quantum yields of [BMIm][Sn$_{4}$Br$_{9}$9] (3 %) and [BMIm][PbCl$_{3}$] (21 %) are low, [BMIm][Sn$_{3}$Cl$_{7}$] shows surprisingly efficient photoluminescence with a quantum yield of 46 %.

Abstract

Nine Ge−Fe carbonyl cluster compounds are prepared via ionic liquids‐based synthesis. This includes the novel compounds [EMIm][Fe(CO)3I(GeI3)], [EHIm][Fe(CO)3I(GeI3)], [BMIm][GeI2{Fe(CO)4}2(μ‐I)][AlCl4]2, [GeI2{Fe(CO)4}2(μ‐I)][Fe(AlBr4)3], [BMIm]2[(FeI2)0.75{Fe(CO)2I(GeI3)2}2], and [EHIm][Fe(CO)4(GeI2)2Fe(CO)3GeI3] as well as the previously reported compounds (Fe(CO)4(GeI3)2, FeI4{GeI3Fe(CO)3}2, and Ge12{Fe(CO)3}8(μ‐I)4 (EMIm: 1‐ethyl‐3‐methylimidazolium, EHIm: 1‐ethylimidazolium, BMIm: 1‐butyl‐3‐methylimidazolium). With this series of compounds, a comparison of synthesis conditions and structural features is possible and, for instance, allows correlating the composition and structure of the respective Ge−Fe carbonyl cluster compounds with the type and acidity of the ionic liquid. With [EMIm][{GeI3}2Fe(CO)3I], moreover, we can exemplarily show the thermal decomposition as a single‐source precursor in the ionic liquid, resulting in bimetallic Ge−Fe nanoparticles with small size and narrow size distribution (7.0±1.4 nm).
