A Novel Type of Alkynylgold(I) Complex. Crystal and Molecular Structures of PPN[Au(Ar)(C⋮CH)] [Ar = C6F5, C6H2(NO2)3-2,4,6]
摘要:
Complexes of the type PPN[Au(acac)(Ar)] [PPN = (Ph3P)(2)N, acac = acetylacetonate], obtained in solution from Tl(acac) and the corresponding PPN[Au(Ar)Cl] derivatives after removal of TlCl, react in situ with ethyne to give a new type of ethynylgold(I) complex, PPN[Au(Ar)(C drop CH)] [Ar = C6F5 (1), C6H4NO2-2 (2), C6H2(NO2)(3)-2,4,6(3)]. The crystal structures of 1 and 3 have been determined.
