Not a chiral helicate but an achiral meso ‐helicate assembles from six catecholate units—bound pairwise by (CH 2 ) 3 chains—and two Ti 4+ as well as four Na + or K + ions. NMR spectroscopic investigations at several temperatures allow the direct observation of the inversion of configuration of the chiral metal centers of the potassium salt.
