A new linear hexaphosphine, rac‐cis,cis,trans‐ bis[(diphenylphosphinomethyl)phenylphosphinomethyl]phenylphosphino}methane (P6), was synthesized and isolated as a pure isomer, confirmed by transforming to the corresponding phosphine sulfide. The methylene‐bridged linear hexaphosphine readily organized flexible gold(I) and silver(I) hexanuclear chains, [M6(μ‐P6)2]X6 (X6=(OTf)6, M=Au (1), Ag (2); X6=Cl2(PF6)4
合成并分离出一种新的线性六膦酸酯,即顺式,顺式,反式双双[(((二苯基膦基甲基)苯基膦基甲基]苯基膦基}甲烷(P 6),并分离为纯异构体,通过转化为相应的膦膦酸酯得到证实。亚甲基桥连的线性hexaphosphine容易组织灵活金(I)和银(I)六核链,[M 6(μ- P 6)2 ] X 6(X 6 =(OTF)6,M =金(1), Ag(2); X 6 = Cl 2(PF 6)4,M = Au(3))。所述hexaphosphine还支持复合物的tetrasilver(I)将[Ag 4(μ- P 6)2 ](OTF)4(4),将其容易地通过用的AgOTf转化为3,揭示两者的急剧交替P 6布置。所述hexagold(I)链显示出显着的红移吸收(~410 nm)与发射(540-580 nm)至1 [5D σ* →6P σ ]和从3 [5D σ* →6P σ金属中心的激发态。新的线性六膦可能是
