Zur Kristallstruktur von Ba3(CrO4)2 / On the Crystal Structure of Ba3 (CrO4) 2

Abstract

For the first time single crystals of Ba3 (CrO4)2 have been examined by X-ray diffraction. The already well known isotypy with Ba3 (PO4)2 has been completed by exact parameters. There are isolated tetrahedrons of O2- surrounding Cr5+ and octahedrons surrounding BaI. The complicated coordination of BaII is discussed.
