| Darstellung und Kristallstruktur vom Arsen(III)arsen(V)oxidhydroxid As305(0H) Preparation and Crystal Structure of the Arsenic(III) Arsenic(V) Oxide Hydroxide As305(0H)  | | | | Abstract
| The title compound was prepared by heating the hydrolysis products of AS2O4 in a sealed tube. The crystal structure was determined and refined to R = 0.058 [P2j./c, a = 1250.4(6), b = 459.3(2), c = 1097.6(6) pm, ß = 118.08(5)°, Z = 4]. The structure consists of infinite layers, containing pyramidal As(III)03 and tetrahedral As(V)04 groups, and stabilised by hydrogen bonding. | | | |

| Darstellung und Struktur von Di-gold(III)bis(selenit)(diselenit), Au2(Se0 3 )2(Se 2 05) Preparation and Crystal Structure of Di-gold(III)bis(selenite) Diselenite, Au2(Se0 3 )2(Se 2 05) | | | | Abstract
| The compound Au 2 (Se0 3) 2 (Se 2 0s) was pre-pared from gold metal and seienic acid at 553 K. The crystal structure [C2/c, a = 2034.4(5), b = 413.0(1), c = 1325.4(3) pm, ß = 115.88(3)°, Z = 4] was refined to R = 0.035. Both gold atoms lie on crystallographic centres of sym-metry and show square planar coordination (Au-0 196.9-201.3 pm). The extended structure consists of three cross-linked systems of the form [ • • • -Au-(selenite or diselenite) -Au----]. | | | |

| 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. | | | |

| 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. | | | |

| Darstellung und Kristallstruktur von Di-gold(III)bis(selenit)oxid, Au2(Se03)20 Preparation and Crystal Structure of Di-gold(III) Bis(selenite) Oxide, Au2(Se03)20 | | | | Abstract
| Au2(Se0s)20 was prepared from gold and excess selenic acid in a sealed tube at 533 K. The crystal structure [P6a2, a = 659.2(2), b = 1183.7(3), c = 399.8(1) pm, Z = 2,R = 0.087] was determined; gold atoms are bridged by oxide ions (lying on twofold axes) and selenite ions. The extended structure consists of polymeric layers parallel to the ««/-plane. The light atom positions are inaccurate because of the presence of a heavy atom in a polar space group. | | | |
