The cover picture shows the first crystallographically characterized cationic triazacyclohexane complex of titanium. The hydrogen atoms of the ring‐CH 2 groups engage in C−H···Cl interactions with the anion (only the shortest shown) and give rise to two characteristic doublets in the 1 H NMR spectrum with shifts that are highly dependent on the N ‐substituents, solvent and anion. The cationic complex is readily formed by the treatment of triazacyclohexanes with excess TiCl 4 which often results in large crystals containing the Ti 2 Cl 9 anion. Details are discussed in the article by R. D. Köhn et al. on p. 3217 ff.
