摘要：
Based on the new binuclear gold(I) complex [(AuCl)(2)(L1)] (1) (L1 = 2,3-bis(diphenylphosphino)maleic anhydride) four new polynuclear compounds were synthesized by reactions of 1 with E(SiMe3)(2) (E = S, Se). During the formation of these new compounds the initial ligand L1 undergoes various transformations (e.g. substitution, hydration or hydrogenation) leading to the new ligands: trans-2,3-bis(diphenylphosphino)succinic anhydride (L2), 2-diphenylphosphino-3-mercapto-maleic anhydride anion (L3), 2-diphenylphosphino-3-selenolato-maleic anhydride anion (L4) and 2,3-bis(diphenylphosphino)succinic acid (L5). In case of using the sulfur species S(SiMe3)(2) a pentanuclear cluster, [Au-5(PPh2)(3)(L3)(2)] (2), and a 24-nuclear cluster, [Au24S6(PPh2)(4)(L3)(8)] (3), could be obtained. With Se(SiMe3)(2) the binuclear complex, [(AuCl)(2)(L2)] (4), and the dodecanuclear cluster, [Au12Se4(L4)(4)(L5)(2)] (5), were yielded.
