On new pathways in the synthesis of metal fluorides

Abstract

It seems to be certain that many metal fluorides unknown and even unexpected today may be obtained. The tools we need are new ideas and new techniques for preparation. I. What has been done? Key examples (1950–1975) II. What can we do? a) Change the starting material: On K 2MnF 6 b) Change the ‘wall’: CsPd 2F 3 - c) Control ourselves: On Ba 2Ni IINi IIIF, d) Be patient: On diamagnetic Cs [CuF 4] e) Use high pressure fluorination: On Ba[NiF 6] f) Drop temperature: On BaAlF 5 g) Knot Rings; On Ba 6F 4[Al 4F 26] and Ru 4F 26 III. What should we do? a)Prepare what should exist b)Seard for what exists in textbooks c)Look at the unbelievable IV. Still open questions.
