Abstract
Alkali metal dihydrogen-antimonides [M(L)x SbH2 ], short: alkali metal antimonides (M=Li, Na, K, Rb, Cs; 1: L=pmdta; 2: L=crown-ether), were prepared from stibine and n-Butyllithium, M(hmds) (hmds=hexamethyldisilazane) or MOtBu, respectively. We developed a generally applicable synthesis route for these compounds and the obtained compounds were examined on their stability depending on the alkali metal and stabilizing additives used, whereby the use of appropriate crown-ethers allowed their isolation and characterization at room temperature. Moreover, the 1,4-dioxane adduct [Na(dioxane)x SbH2 ] was the appropriate starting compound for the synthesis of the first primary silylstibane (Me3 Si)3 SiSbH2 (3) which was characterized by NMR and IR spectroscopy. Reaction of 3 with (Dipp2 NacNac)Ga (Dipp2 NacNac=HC{C(Me)N(Dipp)}2 ; Dipp=2,6-iPr2 C6 H3 ) resulted in the formation of (Dipp2 NacNac)GaH(SbHSi(SiMe3 )3 ) (4) which was furthermore characterized by single crystal x-ray diffraction.

Abstract
Multiple interpnictogen compounds with covalent single bonds between a diarylbismuth fragment and all lighter pnictogens were prepared from the corresponding diarylhalido bismuthanes. The aminobismuthanes Ph2BiNMe2 (1) and Mes2BiNMe2 (2) (Mes = 2,4,6-trimethylphenyl-) have been obtained via a salt metathesis reaction and compound 2 was successfully reacted with tBuNH2 in a condensation reaction to yield Mes2BiNHtBu (3). The bismuthanyl phosphanes Ar2BiPtBu2 (Ar = Ph: 4 and Ar = Mes: 5) and arsanes Ar2BiAstBu2 (Ar = Ph: 8 and Ar = Mes: 9) were also obtained via salt metathesis. Through a trimethylsilyl halide abstraction reaction of the diaryl halido bismuthanes and EtBu(SiMe3)2 (E = P and As), the bismuthanyl phosphanes Ar2BiPtBu(SiMe3) (Ar = Ph: 6; Ar = Mes: 7) and the arsanes Ar2BiAstBu(SiMe3) (Ar = Ph: 10; Ar = Mes: 11) have been prepared. Bismuthanyl stibanes were accessed via a condensation reaction of Mes2SbH with 1 or 2, respectively. The compound Ph2BiSbMes2 (12), which has different substituents at the bismuth and antimony atoms, was isolated and fully characterised. In contrast, the isolation of Mes2BiSbMes2 (13) was not possible due to a dynamic equilibrium with Mes4Bi2 and Mes4Sb2 which was investigated via low-temperature 1H-NMR spectroscopy in solution. The isolated compounds with a single bond between bismuth and the heavy pnictogens arsenic and antimony are rare examples of their kind. All isolated compounds (1-12) were characterised by NMR and IR spectroscopy, mass spectrometry, elemental analysis and single crystal X-ray diffraction.

Abstract
Heteroatomic bridged paracyclophanes were obtained by two independent synthetic approaches. The required precursors consist of para R2SiCl (R = Me, iPr) substituted aromatic rings (2 and 4). They were subsequently functionalised by using NH3, [LiPH2(dme)] or LiAl(PH2)4. In the case of the Me-substituted species 2, the reaction with NH3 directly yielded the Si2N bridged paracyclophane 5. The Si2P incorporated derivative 10 was obtained by lithiation of p-C6H4(SiiPr2PH2)2 (9) and subsequent salt metathesis with the chlorosilane 4. The second approach involves the use of GaEt3 in the formation of four membered (GaPn)2 cycles (Pn = N, P). p-[C6H4{SiiPr2N(H)GaEt2}2]2 (11) and p-[C6H4{SiiPr2P(H)GaEt2}2]2 (12) represent the first examples of stable (GaPn)2cis isomers as the trans species did not appear in solution. Although 11 and 12 show a similar coordination pattern, they differ in the orientation of the aromatic systems: in the solid structure, 11 adopts a - for paracyclophanes so far unique - T-shape conformation of the phenyl rings, while 12 shows the predominant coplanar orientation. All cyclophanes were characterized by X-ray diffraction, elemental analysis, NMR and IR spectroscopy.
