✦ Synopsis

Mittelgroße Kanäle durchziehen die Struktur des ersten Zirconiumfluoridphosphats, das jetzt synthetisiert worden ist (Strukturausschnitt im Bild). Das Gerüst wird aus ZrO~6~‐ und ZrO~5~F‐Oktaedern sowie PO~4~‐ und PO~3~(OH)‐Tetraedern aufgebaut. Durch Variation des als Templat verwendeten Amins sollten weitere offene Gerüststrukturen dieser Art synthetisierbar sein.magnified image

Hydrothermal reaction of Zr(OPr) 4 with H 3 PO 4 in the presence of ethylene diamine and HF yields three crystalline phases; the 1-D [enH 2 ][Zr(HPO 4 ) 3 ], 1, which can grow as needles over 1 mm in length, the 2-D [enH 2 ] 0.5 [Zr(PO 4 )(HPO 4 )], 2, which is found as thin plates, and the previous
