 Title    Die Struktur von GaAs0 4 *2 H20 : Ein neues Mitglied der Variscit-Familie The Structure of GaAsC>4-2 H20 : A New M ember of the Variscite Family  
 Abstract    GaAs0 4 -2 FF0 was synthesized hydrothermally from Ga2Ü3 and a K+-AsC>4~ solution at pH=2. A single crystal structure determination showed that GaAs0 4 -2H20 is isotypic with variscite and therefore the first gallium arsenate with octahedrally coordinated Ga(III). Crys­ tal data: space group Pbca, a = 1016,0(1), b = 886,2(1), c = 994. 1(1) pm, R g = 0,0266. GaAs0 4 -2 H2 0 dehydrates at 439 K with formation of an amorphous material and poor cry­ stalline GaAsC>4. The crystal data of all known compounds with variscite structure have been compiled.
