Tris-chelated compounds with three symmetrical bidendate ligands (in
inorganic chemistry these are the prototypical tris-chelate complexes of
transition metals) can also be conceived as three-bladed propellers with
their helicities specified accordingly.
(M)4-Tris(biphenyl-2,2'-diyl)-A 6 -sulfane
4 Inorganic chemists prefer here the symbols A, A (lamda) and 1' 1, <5 (delta).
