Reactions of EBr3 (E = P, As) with iPr2PAcenapLi (Acenap = acenaphthene-5,6-diyl) afforded the thermally stable peri-substitution supported donor–acceptor complexes, iPr2PAcenapEBr2 3 and 4. Both complexes show a strong P→E dative interaction, as observed by X-ray crystallography and 31P NMR spectroscopy. DFT calculations

    analogy to our successful "PX2+" insertion reactions, an "AsX2+" insertion route was explored to obtain new arsenic halogen cations. Two new salts were prepared: AsBr4+[Al(OR)4]-, starting from AsBr3, Br2 and Ag[Al(OR)4], and I2As-PI3+[Al(OR)]4 from AsI3, PI3 and Ag[Al(OR)4](R=C(CF3)3). The first cation is formally a product of an "AsBr2+" insertion into the Br2 molecule and the latter clearly a "PI2+"
    与我们成功的“ PX2 +”插入反应相似,我们探索了“ AsX2 +”插入途径以获得新的砷卤阳离子。制备了两种新的盐:从AsBr3,Br2和Ag [Al(OR)4]开始的AsBr4 + [Al(OR)4]-和从AsI3,PI3和Ag [Al]的I2As-PI3 + [Al(OR)] 4 (OR)4](R = C(CF3)3)。第一个阳离子形式上是“ AsBr2 +”插入到Br2分子中的产物,而后者显然是“ PI2 +”插入到AsI3分子的As-1键中的产物。两种化合物都通过IR和NMR光谱表征,第一个也是通过X射线结构表征。Ag [Al(OR)4]与AsI3的反应不会导致电离和AgI的形成,而是会导致边缘稳定的Ag(AsI3)2+ [Al(OR)] 4盐。尽管进行了许多尝试,我们仍未能制备其他PX阳离子类似物,例如AsI4 +,As2X5 +和P4AsX2 +(X = Br,I)。为了解释这些负面结果,使用MP2

Two of these compounds were characterised by X-ray diffraction, making them the first structurally characterised examples of AsX2 ligands (X = halogen). AsBr3

  • Formation of M4Se4 cuboids (M = As, Sb, Bi) via secondary pnictogen–chalcogen interactions in the co-crystals MX3·SeP(p-FC6H4)3 (M = As, X = Br; M = Sb, X = Cl; M = Bi, X = Cl, Br)

    The reactions of the group 15 trihalides, MX3 (M = As, Sb, Bi; X = Cl, Br), with the phosphine selenide SeP(p-FC6H4)3 result in the formation of co-crystals of formula MX3·SeP(p-FC6H4)3. No reaction was observed with MI3 (M = As, Sb, Bi). The structures of MX3·SeP(p-FC6H4)3 (M = As, X = Br 2; M = Sb, X = Cl 3; M = Bi, X = Cl 5; M = Bi, X = Br 6) have been established, and are isomorphous, crystallising in the cubic I23 space group. All the structures feature a primary MX3 unit, which has three weak secondary M⋯Se interactions to SeP(p-FC6H4)3 molecules. However, each of these SeP(p-FC6H4)3 molecules bridges three MX3 molecules, resulting in the generation of an M4Se4 (M = As, Sb, Bi) distorted cuboid linked by the pnictogen–chalcogen interactions. Four opposing corners of the cuboid are occupied by the M atom (M = As, Sb, Bi) of an MX3 pyramid, and the other four by the selenium atom of the phosphine selenide.
    第15族三卤化物MX3(M = As, Sb, Bi;X = Cl, Br)与膦硒化物SeP(p-FC6H4)3的反应导致了化学式为MX3·SeP(p-FC6H4)3的共晶体的形成。没有观察到与MI3(M = As, Sb, Bi)的反应。已确定了MX3·SeP(p-FC6H4)3(M = As, X = Br 2;M = Sb, X = Cl 3;M = Bi, X = Cl 5;M = Bi, X = Br 6)的结构,并且它们是同构的,结晶在立方I23空间群中。所有结构都具有一个主要MX3单元,该单元通过三个次级M…Se相互作用与SeP(p-FC6H4)3分子相连。然而,每个SeP(p-FC6H4)3分子桥接三个MX3分子,从而产生了一个由氮族-硫族相互作用连接的M4Se4(M = As, Sb, Bi)扭曲立方体。立方体的四个相对角被MX3金字塔的M原子(M = As, Sb, Bi)占据,另外四个角则被膦硒化物的硒原子占据。
