“…[11] Some recent examples include, for instance, the intermetalloid [CuBi 8 ] 3 + cluster cation in [CuBi 8 ][AlCl 4 ] 2 [Al 2 Cl 7 ], [12] the highly coordinated Sn(II)I 8 subunit in the carbonyl [SnI 8 {Fe(CO) 4 } 4 ][Al 2 Cl 7 ] 2 , [13] the [Sb 10 Se 10 ] 2 + cation in [Sb 10 Se 10 ][AlCl 4 ] 2 , [14] or the heavy-metal porphyrin-analogue [Hg 4 Te 8 (Te 2 ) 4 ] 8À in [DMIm] 8 [Hg 4 Te 8 (Te 2 ) 4 ] ([DMIm] + = 1-decyl-3-methylimidazolium).

Dedicated to Professor Josef Breu on the occasion of his 60 th birthday.The halogenido stannates(II) [BMIm][Sn 3 Cl 7 ] and [BMIm][Sn 4 Br 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, moisturesensitive crystals and exhibit layered anionic networks. [BMIm][Sn 3 Cl 7 ] contains "horseshoe"-like 1 1 (SnCl 1/1 Cl 2/2 ) chains that are linked via [SnCl 3 ] À anions to 1 2 [Sn 3 Cl 7 ] À zigzag-planes. [BMIm][Sn 4 Br 9 ] contains a complex 1 2 [Sn 4 Br 9 ] À network with altogether four different crystallographic Sn 2 + sites and differ-ent 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 1 [PbCl 3 ] À 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 ] (3 %) and [BMIm][PbCl 3 ] (21 %) are low, [BMIm][Sn 3 Cl 7 ] shows surprisingly efficient photoluminescence with a quantum yield of 46 %.

“…Most relevant features of ILs are the high redox stability and the weakly‐coordinating properties. Prominent examples include, for instance, □ 24 Ge 136 as a new modification of germanium (□ indicates non‐occupied regular lattice sites), [4] [Hg 4 Te 8 (Te 2 ) 4 ] 8− with a porphyrin‐analogous structure, [5] or the Zintl‐like cation [CuBi 8 ] 3+ [6] . In addition to the redox stability and the weakly‐coordinating properties, the inherent stabilization of compounds via cation‐anion interactions as well as the presence of voluminous and inert cations/anions are further merits of ILs [7] .…”

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).

“…Besides application in classic solid state chemistry, ILs can be used as reaction media to prepare (oligomeric) metal complexes, metal organic frameworks, coordination polymers [25–35] or cluster compounds incorporating main group elements [36–41] . Within SPP 1708, the synthesis of intermetallic cluster and nanoparticles, [3,42–56] the controlled synthesis of polyanions and cations, [57–61] solvent‐free chalcogenidometal‐containing materials, [62–75] deposition of nanocrystalline materials, [76–80] ionic liquids as precursors for inorganic materials, [81–83] ionic‐liquid‐modified hybrid materials, [84–87] as well as the low‐temperature synthesis of thermoelectric materials [88–92] were investigated. Moreover, theoretical [93–106] and solubility [107–114] aspects during the synthesis process were studied.…”

Within the second funding period of the SPP 1708 “Material Synthesis near Room Temperature”,which started in 2017, we were able to synthesize novel anionic species utilizing Ionic Liquids (ILs) both, as reaction media and reactant. ILs, bearing the decomposable and non‐innocent methyl carbonate anion [CO3Me]−, served as starting material and enabled facile access to pseudohalide salts by reaction with Me3Si−X (X=CN, N3, OCN, SCN). Starting with the synthesized Room temperature Ionic Liquid (RT‐IL) [nBu3MeN][B(OMe)3(CN)], we were able to crystallize the double salt [nBu3MeN]2[B(OMe)3(CN)](CN). Furthermore, we studied the reaction of [WCC]SCN and [WCC]CN (WCC=weakly coordinating cation) with their corresponding protic acids HX (X=SCN, CN), which resulted in formation of [H(NCS)2]− and the temperature labile solvate anions [CN(HCN)n]− (n=2, 3). In addition, the highly labile anionic HCN solvates were obtained from [PPN]X ([PPN]=μ‐nitridobis(triphenylphosphonium), X=N3, OCN, SCN and OCP) and HCN. Crystals of [PPN][X(HCN)3] (X=N3, OCN) and [PPN][SCN(HCN)2] were obtained when the crystallization was carried out at low temperatures. Interestingly, reaction of [PPN]OCP with HCN was noticed, which led to the formation of [P(CN)2]−, crystallizing as HCN disolvate [PPN][P(CN⋅HCN)2]. Furthermore, we were able to isolate the novel cyanido(halido) silicate dianions of the type [SiCl0.78(CN)5.22]2− and [SiF(CN)5]2− and the hexa‐substituted [Si(CN)6]2− by temperature controlled halide/cyanide exchange reactions. By facile neutralization reactions with the non‐innocent cation of [Et3HN]2[Si(CN)6] with MOH (M=Li, K), Li2[Si(CN)6] ⋅ 2 H2O and K2[Si(CN)6] were obtained, which form three dimensional coordination polymers. From salt metathesis processes of M2[Si(CN)6] with different imidazolium bromides, we were able to isolate new imidazolium salts and the ionic liquid [BMIm]2[Si(CN)6]. When reacting [Mes(nBu)Im]2[Si(CN)6] with an excess of the strong Lewis acid B(C6F5)3, the voluminous adduct anion {Si[CN⋅B(C6F5)3]6}2− was obtained.
