Preparative and spectroscopic investigations on the dimorphy of CsNiF3
Description
While the stable modification of CsNiF3 is of green colour, a yellow phase is obtained by fluorination of CsNiCl3 and decomposition of the product 'CsNiF4', which contains Ni4+ and Ni3+ besides Ni2+. The two modifications have the 2L- and 9L-perovskite-structure, respectively, and are characterized by their X-ray patterns and low-temperature ligand field spectra. The differences in colours and spectral band positions are discussed with respect to the Ni-F-Ni bond angles. (orig.)
Abstract (German)
Die stabile Modifikation CsNiF3 ist leuchtend hellgruen; eine gelbe Phase erhaelt man durch Fluorinierung von CsNiCl3 und Aufspaltung des Produkts 'CsNiFu4', das nicht nur Ni2+, sondern auch Ni4+ und Ni3+ enthaelt. Die beiden Modifikationen besitzen eine 2L- bzw. 9L-Perowskitstruktur und unterscheiden sich in ihren Roentgenmustern und Ligandenfeldspektren. Die unterschiedlichen Farben und Spektralbandenpositionen werden im Hinblick auf die Ni-F-Ni-Bindungswinkel diskutiert. (orig./AK)Additional details
