 Title    (H30)[A13(H2P04)6(HP04)2] * 4 H20 - ein Al-O-P vernetztes Phosphat mit Oxoniumionen enthaltenden Hohlräumen (H30)[Al3(H2P04)6(HP04)2] * 4 H20 - a <g Al-O-P Linked Phosphate with Hollows Containing Oxonium Ions  
 Abstract    The crystal structure of (H30)[Al3(H2P04)6(HP04)2] • 4 H20 contains layers consisting of AIOÖ octahedra which share vertices with 02P(0H)2 and 03P(0H) tetra-hedra. Within these layers there are vacancies (hollows) which are occupied by H30+ species. Water molecules are fixed between neigh-bouring layers by hydrogen bonds. The identity of some other related phosphates is discussed with respect to the crystal structure described in this paper.

 Title    A New Form of A1(H2P0 4 )3 with Three-Dimensional Al-O-P Crosslinking  
 Abstract    3 [A1(H 2 P0 4) 3 ] has been prepared and characterized as a second modification of alu-minium tris(dihydrogenphosphate). Its crystal structure is a three-dimensional Al-O-P network of AlOß octahedra, linked by common vertices through 0 2 P(0H) 2 tetrahedra with six further octahedra. Each P-OH group is a proton donor as well as a proton acceptor of 0-H---0 hydrogen bonds arranged in angular chains of alternating polarity in macroscopic domains.
