 Title    Synthesen, Kristallstrukturen und Eigenschaften von Trisilber-und Trikalium-tri-/x-imido-cyclotriphosphat, Ag3(P 0 2NH)3 und K3(P 0 2NH)3 Syntheses, Crystal Structures, and Properties of Trisilver and Tripotassium Tri-^-im ido Cyclotriphosphate, Ag3(P 0 2N H)3 and K3(P 0 2N H)3 N. Stock  
 Abstract    Coarse crystalline Ag3(P 0 2NH)3 (1) and K3(P 0 2NH)3 (2) are obtained by addition of an aqueous solution of A gN 03 to an acidified solution of Na3(P 0 2NH)3 • 4H20 and by diffusion controlled addition of ethanol to a solution of K3(P 0 2NH)3 in water, respectively. The crystal structures of 1 and 2 have been determined by single crystal X-ray methods (Ag3(P 0 2NH)3: P2,/c; a = 1166.6(1), b = 786.4(1), c = 997.8(1) pm, ß = 106.91(1)°; Z = 4. K3(P 0 2NH)3: R3; a = 1271.4(2), c = 1017.9(2) pm, Z = 6). In Ag3(P 0 2NH)3 the cyclic anion is markedly distorted because of interactions between Ag+ and one nitrogen atom of the anion. In K3(P 0 2NH)3 the trimetaphosphimate ring shows a chair conformation and two cyclic anions are connected to each other by hydrogen bonds. DTA/TG investigations show thermal decomposition above 275 and 250 °C for 1 and 2, respectively.
