of two hydrides in the isolated clusters is confirmed by the synthesis and characterization of its deuteride analogue [Cu15(D)2(S2CNR2)6(C2Ph)6]+, and a single-crystal neutron structure of 2H. Structural characterization of 1H reveals a new bicapped icosahedral copper(I) cage encapsulating a linear copper dihydride (CuH2)− unit. Reaction of 3H with Au(I) salts yields a highly luminescent [AuCu12(S2CNiBu2)6(C2Ph)4]+
高活性二氢化铜簇,[Cu 15 (H) 2 (S 2 CNR 2 ) 6 (C 2 Ph) 6 ](PF 6 ) R = n Bu ( 1 H ), n Pr ( 2 H ), i Bu ( 3 H )},在[Cu 28 H 15 S 2 CN n Bu 2 } 12 ](PF 6) 与十当量的苯乙炔。发现它们是形成早先报道的双电子超原子 [Cu 13 (S 2 CNR 2 ) 6 (C 2 Ph) 4 ] + 的中间体。通过使二硫代氨基甲酸钠盐、[Cu(CH 3 CN) 4 ](PF 6 )、BH 4 -和苯乙炔反应获得更好的产率。通过其氘化物类似物 [Cu 15 (D) 2 (S 2 CNR 2 ) 6的合成和表征证实了在分离的簇中存在两种氢化物(C 2 Ph) 6 ] +,以及2 H的单晶中子结构。1 H 的结构表征揭示了一种新的双封端二十面体铜 (I) 笼,其封装了线性二氢化铜
