“…There are long inter-chain Bi···Br contacts of 3.883(1), 3.940(1) Ǻ, which slightly exceed the sum of the Van der Waals radii (3.85 Ǻ) [17]. The chain structure is similar to that found in BiPh 2 Cl [18], whereas Bi(mesityl) 2 Br is better described as composed of trigonal pyramidal monomers with very long Bi···Br (3.795 Ǻ) contacts linking them into chains [19]. The BiÀC distances in BiMe 2 Br of 2.235(7)À2.256(6) Ǻ, are shorter than in BiMeCl 2 (2.330(1) Ǻ) [10], but similar to those in Bi(mesityl) 2 Br (2.268(12), 2.270(10) Ǻ) [19].…”

a b s t r a c tMethyldihalobismuthines, BiMeX 2 (X ¼ Cl or Br) prepared from MeLi and a stoichiometric amount of BiX 3 in thf, react with 1,10-phenanthroline, 2,2 0 -bipyridyl or Me 2 NCH 2 CH 2 NMe 2 (LÀL) in thf or MeCN to give [BiMeX 2 (LÀL)], which are poorly soluble in non-polar solvents. X-Ray structures of [BiMeBr 2 (LÀL)] and of [BiMeCl 2 (Me 2 NCH 2 CH 2 NMe 2 )] show discrete square pyramidal molecules with apical methyl groups, and no intermolecular contacts within the sum of the appropriate Van der Waals radii. The structure of BiMe 2 Br is a 1-D polymer chain with bromine bridges containing a pseudo-trigonal bipyramidal geometry at bismuth. The reactions of BiMe 2 X with the bidentate N-donor ligands result in disproportionation to also form [BiMeX 2 (LeL)]. An unusual [BiMeBr 4 ] 2À anion in the salt [Li(H 2 O)(1,10-phen) 2 ][Li(1,10-phen) 2 (m-Br)BiMeBr 3 ]$thf, was isolated as a by-product and shows a LiÀBrÀBi bridge to one of the Li cations. BiMe 2 Br disproportionates on reaction with [M(CO) 5 (thf)] (M ¼ Cr or W) to form [M(CO) 5 (BiMe 3 )].

“…Moreover, diaryl bismuth halides of the heavier halogens can be prepared via halogen exchange reactions with alkaline or earth alkaline metal halides and diaryl bismuth halides of lighter halogens [1,11,12] . It is common for bismuth halides to show secondary bonding interactions between bismuth and halogen atoms of neighboring molecules in the solid state [8–10,12–14] . The tendency for intermolecular interactions lowers when sterically more demanding substituents are employed [2,4] .…”

“…Consequently, steric demand greatly influences the solid state structure of substituted halido bismuthanes. Most dialkyl and diaryl halido bismuthanes with low steric bulk around the bismuth center form one dimensional polymeric chains with alternating bismuth and halide atoms [9,10,12–14] . Sterically shielded dialkyl and diaryl halido bismuthanes form monomers, [2,4] dimers [8] or oligomers [12] .…”

2,6‐Diisopropylphenyl‐Substituted Bismuth Compounds: Synthesis, Structure, and Reactivity

et al. 2021

The 2,6‐diisopropylphenyl (Dipp) substituent is introduced to diaryl bismuth chemistry. Dipp2BiBr (1‐Br) was prepared by a Grignard reaction and subsequently used as precursor for synthesis of the other diaryl halido bismuthanes Dipp2BiX (1‐X, X=F, Cl, I) and the corresponding triflate Dipp2BiOTf (1‐OTf). Moreover, 1,1,2,2‐tetrakis(2,6‐diisopropylphenyl)dibismuthane (2) was prepared. All isolated compounds were characterized via single crystal X‐ray diffraction analysis, NMR spectroscopy, IR spectroscopy, and elemental analysis. Furthermore, the reactivity of a dibismuthane towards elemental sulfur was investigated, and the formed dibismuthanyl tri‐ and pentasulfide (3 a, 3 b) were characterized by single crystal X‐ray analysis. Functionalization of the diaryl halido bismuthanes with LiPtBu2 or tBu2PTMS (TMS=SiMe3) gives access to the interpnictogen compound Dipp2Bi−PtBu2 (4), which shows a rare example of a covalent Bi−P bond.

“…Apart from a small number of compounds with lead-metal bonds or with relatively simple anions (tetramethyllead, [1] trimethyllead chloride, [2] trimethyllead iodide, [3] trimethyllead acetate, [4] trimethyllead 2-furate, [5] trimethyllead diphenylphosphinate [6] or trimethyllead methylthiolato [7] ), the only such structure in the CSD [8] is that of the complex bis(tetraphenylimidodiphosphanato)dimethyllead(IV), which was obtained in the recrystallization of the corresponding trimethyllead compound. [6] This paucity of information is probably related to the intrinsic instability of methyllead(IV) compounds, which are more unstable than the corresponding phenyl derivatives.…”

The reaction of the bis(thiosemicarbazone) of dimethyl pyridine‐2,6‐diyl diketone, H2DAPTSC, with PbMe2(OAc)2, PbMePh(OAc)2 or PbPh2(OAc)2 in MeOH afforded the complexes [PbMe2(DAPTSC)], [PbMePh(DAPTSC)] or [PbPh2(DAPTSC)] (in the first two cases together with [Pb(DAPTSC)]). X‐ray crystallography of the Pb(IV) complexes showed that the metal has a pentagonal bipyramidal coordination sphere. The N3,S2‐bound DAPTSC2– anion occupied the equatorial plane and the organic groups were in the apical positions. These compounds retain the same coordination mode in DMSO solution. DAPTSC2– is also N3,S2‐bound in [Pb(DAPTSC)], a complex with a stereochemically active PbII lone pair. The reaction of PbPh2Cl2 with H2DAPTSC, also in methanol at room temperature, afforded [PbPh2(H2DAPTSC)]2[PbPh2Cl4]Cl2·6CH3OH. X‐ray crystallography of this centrosymmetric complex showed it to consist of two [PbPh2(H2DAPTSC)]2+ cations of similar structure to the neutral [PbR2(DAPTSC)] complexes, together with a trans‐octahedral [PbPh2Cl4]2– anion and two Cl– anions. This compound decomposes in DMSO solution, probably evolving to H2DAPTSC and PbPh2Cl2(DMSO)n. In order to evaluate the changes undergone by H2DAPTSC under metallation, the X‐ray structure of the free molecule was also determined.(© Wiley‐VCH Verlag GmbH & Co.
