  bibo_abstract:
  - The substitution of heavier, more metallic atoms into classical organic ligand
    frameworks provides an important strategy for tuning ligand properties, such as
    ligand bite and donor character, and is the basis for the emerging area of main-group
    supramolecular chemistry. In this paper, we explore two new ligands [E(2-Me-8-qy)3]
    [E = Sb (1), Bi (2); qy = quinolyl], allowing a fundamental comparison of their
    coordination behavior with classical tris(2-pyridyl) ligands of the type [E′(2-py)3]
    (E = a range of bridgehead atoms and groups, py = pyridyl). A range of new coordination
    modes to Cu+, Ag+, and Au+ is seen for 1 and 2, in the absence of steric constraints
    at the bridgehead and with their more remote N-donor atoms. A particular feature
    is the adaptive nature of these new ligands, with the ability to adjust coordination
    mode in response to the hard–soft character of coordinated metal ions, influenced
    also by the character of the bridgehead atom (Sb or Bi). These features can be
    seen in a comparison between [Cu2{Sb(2-Me-8-qy)3}2](PF6)2 (1·CuPF6) and [Cu{Bi(2-Me-8-qy)3}](PF6)
    (2·CuPF6), the first containing a dimeric cation in which 1 adopts an unprecedented
    intramolecular N,N,Sb-coordination mode while in the second, 2 adopts an unusual
    N,N,(π-)C coordination mode. In contrast, the previously reported analogous ligands
    [E(6-Me-2-py)3] (E = Sb, Bi; 2-py = 2-pyridyl) show a tris-chelating mode in their
    complexes with CuPF6, which is typical for the extensive tris(2-pyridyl) family
    with a range of metals. The greater polarity of the Bi–C bond in 2 results in
    ligand transfer reactions with Au(I). Although this reactivity is not in itself
    unusual, the characterization of several products by single-crystal X-ray diffraction
    provides snapshots of the ligand transfer reaction involved, with one of the products
    (the bimetallic complex [(BiCl){ClAu2(2-Me-8-qy)3}] (8)) containing a Au2Bi core
    in which the shortest Au → Bi donor–acceptor bond to date is observed.@eng
