Summary

The chemistry of the topotactic transformation of the Zintl phases CaSi2 and CaGe2 into sheet polymers is discussed. While silicon sheet polymers are predominantly obtained in the form of the partially hydroxyl-substituted siloxene, germanium sheet polymers are found to be pure polygermyne. Only after extended reaction times, the Ge-analogue germoxene is formed.
