    Description / Table of Contents: Preparation and Crystal Structure of K3La(NH2)6.Single crystals of K3La(NH2)6 were obtained by the reaction of the metals (3 K + 1 La) during five days at 200°C and 4000 atm NH3 pressure. The compound crystallizes monoclinic with a = 6.74, b = 11.67, c = 7.23 Å and β = 108.1°; the space group is C2/m (No. 12). The lattice contains 2 formula units. The amide ions are arranged in a strongly distorted cubic closepacking. All cations occupy edging anion-octahedra.

Die Verbindung kristallisiert monoklin mit a = 6,74, b = 11,67, c = 7,23 Å und β = 108,1°; die Raumgruppe ist C2/m (Nr. 12). Die Elementarzelle enthält 2 Formeleinheiten. Die Amidionen sind stark deformiert kubisch dicht angeordnet. Alle Kationen besetzen kantenverknüpfte Oktaederlücken des Anionenteilgitters.
