The reaction of In(CH2Ph)3 and InMes3 with BF·OEt2 forms the corresponding monofluorides (PhCH2)2InF(1) and Mes2InF (2), while [iPr2In][BF4] (3) is precipitating, when BF3·OEt2 is given to a solution of In(iPr)3 in ether. 3 can be recrystallized from an Et2OTHF-mixture as colorless needles of [iPr2In(THF)2][BF4] (4). An X-ray structure determination of 4 shows [iPr2In(THF)2]+-ions, bridged by [BF4]−-ions

the interactions of f-block metal ions with p-block polyanions in multinary cluster compounds is becoming increasingly attractive but remains a challenge in terms of both the synthetic approach and the control of the structures that are formed during the syntheses. So far, two types of reactions were dominant for the formation of corresponding clusters: the reaction of binary anions of p-block elements
研究多元簇化合物中 f 区金属离子与 p 区聚阴离子的相互作用变得越来越有吸引力,但在合成方法和合成过程中形成的结构控制方面仍然是一个挑战。到目前为止,两种类型的反应对于相应簇的形成占主导地位:p区元素的二元阴离子在1,2-二氨基乙烷( en )溶液中的反应或有机铋化合物与相应的f区金属的反应THF 中的络合物。在此,我们报道了 [La@In 2 Bi 11 ] 4– ( 1 ) 及其双 μ-Bi 桥类似物在双 [K(crypt-222)] +配位 [K(crypt-222) 中的合成。 )] 2 [La@In 2 Bi 11 ](μ-Bi) 2 [La@In 2 Bi 11 ]} 4– ( 2 ) 作为它们的 [K(crypt-222)] +盐 [K(crypt-222) ] 4 1和 [K(crypt-222)] 4 2分别通过 [InMes 3 ] 和 [La(C 5 Me 4 H)

The reaction of MMes(3) (M = Ga, In; Mes = 2,4,6-Me(3)C(6)H(2)) with CsF in acetonitrile yields the trimesitylfluorometalates [Cs(MeCN)(2)}Mes(3)MF}](2) . 2MeCN([1](2) . 6MeCN, M = Ga; [2](2) . 6MeCN, M = In). Ga(CH(2)Ph)(3) gives with CsF under the same conditions the salt [Cs(PhCH(2))(3)GaF}](2) . 2MeCN ([3](2) . 2MeCN). The treatment of 1 equiv CsF with 2 equiv of GaMes(3) does not lead to Cs[Mes(3)GaFGaMes(3)] but to [1](2) . 6MeCN and the adduct [Mes(3)Ga(MeCN)] (4). [1](2) . 6MeCN-4 have been characterized by NMR, IR, and MS techniques as well as by X-ray analyses. [1](2) . 6MeCN and [2](2) . 6MeCN are solvated ion pairs in acetonitrile, while [3](2) . 2MeCN shows a monomer-dimer equilibrium. According to the X-ray structure determinations, [1](2) . 6MeCN and [2](2) . 6MeCN are isostructural and contain Cs-F four-membered rings. The fluorine centers at the rings are bound to the metallane groups. Each cesium cation is coordinated by two molecules of acetonitrile and by one mesityl group in a eta(3)-fashion. The basic structural feature of [3](2) . 2MeCN is also a Cs-F four-membered ring; however, the cations in [3](2) . 2MeCN are surrounded by three phenyl groups of the benzyl substituents. The three eta(6)-bound phenyl rings are contributed from two different metallane units. 4 possesses a distorted tetrahedral coordination sphere with a low pyramidalization of the Ga center (angular sum: 355 degrees).
