  Gold(I) Chloride Complexes of Polyphosphine Ligands with Electron-Rich Arene Spacer: Gold–Arene Interactions

  摘要：

  The reactions of Au(tht)Cl (tht = tetrahydrothiophene) with the electron-rich-arene-spacer-containing polyphosphine ligands N,N'-bis((diphenylphosphino)methyl)benzene-1,4-diamine (Dpba), N,N'-bis((diphenylphosphino)methyl)naphthalene-1,5-diamine (Dpna), N,N,N',N'-tetralcis((diphenylphosphino)methyl)benzene-1,4-diamine (Pbaa), N,N,N',N'-tetrakis-((diphenylphosphino)methyl)naphthalene-1,5-diamine (Pnaa), and N,N,N',N'-tetralcis((diphenylphosphino)methyl)biphenyl-4,4'-diamine (Pbbaa) lead to [Dpba(AuCl)2] (1), [Dpna(AuCl)(2)] (2), [Pnaa(AuCl)(4)] (3), [Pbbaa(AuCl)(4) (4). and [Pbaa(AuCl)(4)] (5), which are characterized by H-1 and P-31 NMR, IR, elemental analysis, and X-ray crystal structure analysis. These complexes exhibit weak Au arene interactions with the electron-rich arene spacer, while the Au arene interactions are modified by a combination of electronic and steric effects from the ligands. Different from monomeric complexes 1, 2, 3, and 4, complex 5 in the solid state exhibits a centrosymmetric trimeric unit that is constructed by intermolecular Au center dot center dot center dot Au interactions between the central molecule and the two symmetry-related terminal molecules and in which the conformation of the central molecule is different from that of the two symmetric terminal molecules. On the basis of the Kochi's geometric criteria and the crystal structural parameters relating to Au-arene interactions, the Au center dot center dot center dot C-arene contacts in 3 and 4 feature nearly eta(2)-arene interactions, while the Au center dot center dot center dot C-arene contacts in 5 can be described as eta(1)-arene interactions, and the Au center dot center dot center dot C-arene contacts in 1 and 2, are very weak due to intermolecular N-H center dot center dot center dot Cl interactions.
