Abstract
The structure of hemimorphite, Zn4(OH)2Si2O7 · H2O, has been redctermined by means of hk0 and 0kl electron-density projections. The Si2O7 ion consists of two SiO4 tetrahedra with a shared corner; the Si–O–Si angle is 133° and the Si–O distances are 1.72 Å (central) and 1.60, 1.62 Å (peripheral). Preliminary results for thortvoitite, Sc2Si2O7, (with H. Lynton) show that the crystals do not have 2/m symmetry and that the Si–O–Si angle is not 180° as formerly supposed.Keywords
