Abstract
The reaction of MeSi{Me2SiN(Li)(p-tol)}3(Et2O)2 with SnCl2 in a 1:1 molar ratio leads the tris(amido)stannate MeSi{Me2SiN(p-tol)}3SnLi(Et2O) (1), which further reacts with neutral AuCl(PPh3) and anionic PPNAuCl2, PPNAuRCl (R = C6F5. mes), and chlorogold(I) complexes yielding Au(MeSi{Me2SiN(p-tol)}3Sn)(PPh3) (2) and PPNAu(MeSi{Me2SiN(p-tol)}3Sn)2 (3) and Au(MeSi{Me2SiN(p-tol)}3Sn)(R) (R = C6F5, 4; R = mes, 5), respectively. The reaction of 1 with the dinuclear gold(II) derivative Au2(CH2PPh2CH2)2Cl 2 in a 1:2 ratio affords Au2(CH2PPh2CH2)2(Me 2i{Me2SiN(p-tol)}3Sn)2 (6). In a similar way but starting from PPNAu(C6F5)3,Cl and reacting with 1 in a 1:1 ratio, the Au(III) complex PPNAu(MeSi{Me2SiN(p-tol)}3Sn)(C6F 5)3 (7) has been obtained. X-ray crystal structure analyses were performed for compounds 2 and 6, establishing the Sn-Au bonds d(Au-Sn) = 2.5651(13) and 2.6804(13) Ã , respectively). Compound 6 has a nearly linear Sn-Au-Au-Sn array and features the first examples of tin-gold(II) bondsKeywords
