Meso complex versus helicate: A naphthalene‐bridged bis(benzene‐o‐dithiol) ligand reacts with Ti4+ to give both dinuclear triple‐stranded meso complexes and helicates, depending on the counterion employed during synthesis. DFT calculations performed with a simplified complex revealed that the interconversion of Λ to its Δ enantiomer proceeds via a C3h‐symmetric transition state (see figure).

Reaction of the 1,5-diamidonaphthalene bridged bis(benzene-o-dithiol) ligand H4-B with Ti4+ leads to the unexpected formation of a dinuclear meso-complex anion [Ti2(B)3]4−, while the catechol analog H4-A has been reported to yield the tetrahedral [M4(A)6]8−cluster.
