文摘

The reaction of [(AuCl)₂dppm] (dppm = Ph₂PCH₂PPh₂) with PhP(SiMe₃)₂ and P(SiMe₃)₃ leads to the formation ofthe gold cluster compound [Au₁₈(P)₂(PPh)₄(PHPh)(dppm)₆]Cl₃ (1). The crystal structure investigation shows a centralAu₇P₂ unit formed by two P centered gold tetrahedra sharing the central gold corner. This central unit is surroundedby a 10-membered Au₅P₅ ring which, together with the remaining six gold atoms, builds two Au₄P rectangular andtwo Au₃P trigonal pyramids. The different structure motifs are connected by the phosphine ligands. The compoundhas been characterized using microanalysis, IR spectroscopy, ESI-MS, and ³¹P NMR techniques. Luminescencemeasurements have also been carried out.
