The ligands KS(2)CN(Bz)CH(2)CH(2)N(Bz)CS(2)K (K(2)L(1)), N(CH(2)CH(2)N(Me)CS(2)Na)(3) (Na(3)L(2)), and the new chelates {(CH(2)CH(2))NCS(2)Na}(3) (Na(3)L(3)) and {CH(2)CH(2)N(CS(2)Na)CH(2)CH(2)CH(2)NCS(2)Na}(2) (Na(4)L(4)), react with the gold(I) complexes [ClAu(PR(3))] (R = Me, Ph, Cy) and [ClAu(IDip)] to yield di-, tri-and tetragold compounds. Larger metal units can also be coordinated by the longer, flexible linker, K(2)L(1). Thus two equivalents of cis-[PtCl(2)(PEt(3))(2)] react with K(2)L(1) in the presence of NH(4)PF(6) to yield the bimetallic complex L(1){Pt(PEt(3))(2)}(2)(2). The compounds [NiCl(2)(dppp)] and [MCl(2)(dppf)] (M = Ni, Pd, Pt; dppp = 1,3-bis(diphenylphosphino)propane, dppf = 1,1'-bis(diphenylphosphino)ferrocene) also yield the dications, L(1){Ni(dppp)}(2) and L(1){Ni(dppf)}(2) in an analogous fashion. In the same manner, reaction between [(L'(2))(AuCl)(2)] (L'(2) = dppm, dppf; dppm = bis(diphenylphosphino)methane) and KS(2)CN(Bz)CH(2)CH(2)N(Bz)CS(2)K yield [L(1){Au(2)(L'(2))}(2)]. The molecular structures of L(1){M(dppf)}(2)(2) (M = Ni, Pd) and [L(1){Au(PR(3))}(2)] (R = Me, Ph) are reported.
配体 KS(2)CN(Bz)CH(2)CH(2)N(Bz)CS(2)K(K(2)L(1))、N(CH(2)CH(2)N(Me)CS(2)Na)(3)(Na(3)L(2))，以及新的螯合物{(CH(2)CH(2))NCS(2)Na}(3)(Na(3)L(3))和{CH(2)CH(2)N(CS(2)Na)CH(2)CH(2)CH(2)NCS(2)Na}(2)(Na(4)L(4))，与金（I）配合物[ClAu(PR(3))]（R = Me、Ph、Cy）和[ClAu(IDip)]反应，生成二、三、四金化合物。较长的柔性连接体 K(2)L(1)也可以与较大的金属单元配位。因此，两个当量的顺式-[PtCl(2)(PEt(3))(2)]与 K(2)L(1)在 NH(4)PF(6)的存在下反应，生成双金属配合物L(1){Pt(PEt(3))(2)}(2)(2)。化合物[NiCl(2)(dppp)]和[MCl(2)(dppf)]（M = Ni、Pd、Pt；dppp = 1,3-双（二苯基膦基）丙烷，dppf = 1,1'-双（二苯基膦基）二茂铁）也以类似的方式生成二阳离子L(1){Ni(dppp)}(2)和L(1){Ni(dppf)}(2)。同样，[(L'(2))(AuCl)(2)]（L'(2) = dppm、dppf；dppm = 双（二苯基膦基）甲烷）与 KS(2)CN(Bz)CH(2)CH(2)N(Bz)CS(2)K 之间的反应生成[L(1){Au(2)(L'(2))}(2)]。报道了L(1){M(dppf)}(2)(2)（M = Ni、Pd）和[L(1){Au(PR(3))}(2)]（R = Me、Ph）的分子结构。
