Abstract

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.
