Symmetry from within: Coordination of a triphosphanyl–borane ligand to gold(I) and platinum(0) affords metallaboratranes exhibiting C3 symmetry both in solution and in the solid state. Such a helical geometry is supported by axial M→B dative interactions and results from the envelope conformations of the PCCBM metallacycles.
