It takes two to tango: When ligand H4-1 (see scheme) reacts with MoIV and TiIV, the different binding preferences of the O–O and S–S donor groups lead to the formation of the helicate [TiMo(1)3]4− with a parallel orientation of the ligand strands. With different cations, the supramolecular complexes {Λ,Λ-[TiMo(1)3]-(PNP)-Δ,Δ-[TiMo(1)3]}7− and {Δ,Δ-[TiMo(1)3]-Na-Δ,Δ-[TiMo(1)3]}7− can be crystallized. PNP=bis(triphenylphosphoranylidene)ammonium.
