    previously described Ce or Pr complexes containing the (C5Me5)- ligand. The η1-C5Me5 alkyl-like reactivity of the (C5Me5)3Ln complexes was investigated with CO, ethylene, THF, and H2. The sterically induced reduction (SIR) reactivity of the (C5Me5)3Ln complexes was examined with SePPh3, AgBPh4, C8H8, and phenazine. All of these data indicate that (C5Me5)3Ln reactivity increases with decreasing size

    (C(5)Me(5))(2)Sm (2 equiv) reacts with Ph(2)EEPh(2) to give (C(5)Me(5))(2)SmEPh(2) (E: P, 1; As, 2), while (C(5)Me(5))(2)Sm(THF)(2) (2 equiv) reacts with Ph(2)EEPh(2) to give (C(5)Me(5))(2)Sm(EPh(2))(THF) (E: P, 3; As, 4). 3 and 4 are also available from the reactions of 1 and 2 with THF. 3 and 4 undergo further reaction to produce the THF ring-opened products (C(5)Me(5))(2)Sm[O(CH2)(4)EPh(2)](THF) (E: P, 5; As, 6). (C(5)Me(5))(2)Sm (4 equiv) reacts with Ph(2)EEPh(2) to give the mixed-valent (C(5)Me(5))(2)Sm(mu-EPh(2))Sm(C(5)Me(5))(2) (E: P, 7; As, 8). These compounds are also available from the reaction of 1 and 2 with (C(5)Me(5))(2)Sm.

As a result, one phenyl group is closer to the metal (2.901 Angstrom minimum Sm-C distance). 4, crystallized from toluene (P2(1)/n; a 10.713(9) Angstrom, b = 14.143(11) Angstrom, c 21.620(16) Angstrom, beta = 101.08(6)degrees, V = 3215(4) Angstrom(3), D-calcd = 1.492 Mg/m(3); Z = 4; T = 163 K), and 6, crystallized from-hexanes (P2(1)/n; a 9.3958(16) Angstrom, b = 22.245(3) Angstrom, c 17.931(3) Angstrom, beta = 96.497(11)degrees, V = 3724(1) Angstrom(3), D-calcd = 1.416 Mg/m(3); Z = 4; T = 163 K), have conventional eight-coordinate, bent metallocene structures.

    Zintl phases of arsenic and molecular compounds containing Zintl‐type polyarsenide ions are of fundamental interest in basic and applied sciences. Unfortunately, the most obvious and reactive arsenic source for the preparation of defined molecular polyarsenide compounds, yellow arsenic As4, is very inconvenient to prepare and neither storable in pure form nor easy to handle. Herein, we present the
    包含Zintl型聚砷离子的砷和分子化合物的Zintl相在基础科学和应用科学中具有根本的意义。不幸的是,用于制备确定的分子聚砷化物化合物的最明显的和反应性的砷源,即黄色砷As 4,制备起来非常不方便,而且不能以纯净形式储存,也不易于处理。在这里,我们介绍了元素As 0纳米粒子(As 0 Nano,d = 7.2±1.8 nm)的合成和反应性,这些纳米粒子已成功地用作还原性元素化学中的反应性砷源。从开始的[Cp * 2 SM](CP * =η 5 -C 5我5),钐polyarsenide配合物[(CP * 2 SM)2(μ - η 2:η 2 -As 2)]和[(*的Cp 2 SM)4作为8 ]从作为获得0纳米,从而产生最大的分子中的多分子砷化物,并避免了As 4在制备化学中的使用。
