Magnetism in coordination complexes

Neu dargestellt wurden K[RhF6], Rb[RhF6] (hex.) Ba[GeF6]-Typ (a = 7,468 Å, c = 7,360 Å bzw. a = 7,611 Å, c = 7,625 Å) und Na RhF6, LiSbF6-Typ (a = 5,246 Å, c = 14,627 Å). Erneut dargestellt wurde Cs[RhF6] (Ba[GeF]6-Typ, a = 7,818 Å, c = 8,021 Å. Alle Verbindungen zeigen eine leuchtend orange Farbe. Magnetische Messungen und der Madelunganteil der Gitterenergie (MAPLE) werden diskutiert. We obtained hitherto unknown K[RhF6] and Rb[RhF6] of (hexag.) Ba[GeF6]-type (a = 7,468 Å, c = 7,360 Å and a = 7,611 Å, c = 7,625 Å) as well as Na RhF6 of (hexag.) LiSbF6-type (a = 5,246 Å, c = 14,627 Å). Cs[RhF6] was prepared again (Ba[GeF6]-type a = 7,818 Å, c = 8,021 Å). All compounds are coloured bright-orange. Magnetic measurements and the Madelung-part of lattice-energy (MAPLE) are discussed.
