The cover page shows the highly symmetrical cluster [[C5Me5]3Re3O6]2⊕, which forms surprisingly readily from the trioxo half-sandwich complex [[C5Me5]Re3O3] and PPh3 in aerated tetrahydrofuran. M3O6 structural groups of this kind were hitherto unknown. ReO4⊕ is formed as the counterion. The salt—blue-green crystals—is stable towards oxygen. Further details are reported by W. A. Hermann et al. on p. 50.
