The metal-controlled self-assembly of nanometer-sized
trinuclear cylinder-like assemblies is described.
The 1,3,5-triphenylbenzene-derived trisimidazolium salt
[1](PF6)3 reacts with 1.5 equiv of Ag2O to yield the trinuclear
AgI hexacarbene complex [2](PF6)3, where three AgI ions are
sandwiched in between two C3-symmetric tris-NHC ligands.
Transmetalation of [2](PF6)3 with 3 equiv of [AuCl(SMe2)] or
CuI yields the trinuclear AuI hexacarbene complex [3](PF6)3 or
the trinuclear CuI hexacarbene complex [4](PF6)3, respectively,
with retention of the metallosupramolecular structure. The
1,3,5-triphenylbenzene ligand in the gold complex adopts a
nonplanar geometry to allow π interactions between the central phenyl rings. [-]
