 Title    Darstellung und Kristallstruktur von Arsen(III)phosplior(V)oxid, AsP04 Preparation and Crystal Structure of Arsenic(III) Phosphorus(V) Oxide, AsP04  
 Abstract    The compound ASPO4 was prepared from AS2O3 and P2O5 in a sealed tube at 673 K. The crystal structure, isostructural with As02, was refined to R = 0.021 [Pnma, a — 843.15(10), b = 502.29(10), c = 720.39(12) pm, Z = 4]. The structure consists of infinite layers. The arsenic(III) atoms are coordinated by three oxygen atoms at right angles; phosphorus(V) by four oxygens in the form of a distorted tetrahedron.

 Title    Darstellung und Kristallstruktur von Arsen(III)phosphor(V)oxidhydroxid As2P05(0H) Preparation and Crystal Structure of the Arsenic(III) Phosphorus(V) Oxide Hydroxide As2POs(OH)  
 Abstract    The title compound was prepared by heating the hydrolysis products of ASPO4 in a sealed tube. The crystal structure was determined and refined to R = 0.028 [P2i/n, a = 454.5(1), b = 1229.0(2), c = 972.8(3) pm, ß = 100.13(2)°, Z = 4]. The structure, which is not isostructural with As30s(0H), consists of infinite layers, containing pyramidal AS(III)03 and tetrahedral P(V)04 groups, and stabilised by hydrogen bonding of the form P-O-H -O-P.
