    Description / Table of Contents: Zweiwertiges Samarium: Synthese und Kristallstrukturen von Sm4OCl6 und KSm2Cl5Einkritalle von Sm4OCl6 und KSm2Cl5 erhält man bei der metallothermischen Reduktion von SmCl3 mit Lithium (in Gegenwart von Sm2O3 oder SmOCl) bzw. Kalium bei höheren Temperaturen in verschweißten Tantalbehältern. Sm4OCl6 (hexagonal, P63mc, Z = 2, a = 946,59(4); c = 717,88(4) pm) und KSm2Cl5 (monoklin, P21/c, Z = 4, a = 888,06(6); b = 784,81(5); c = 1262,77(8) pm; ß = 90,085(6)°) enthalten beide zweiwertiges Samarium. In Sm4OCl6 treten mit 236,0 und 237,6 (3x) pm bemerkenswert kurze Abstände Sm2+—O2- innerhalb des Tetraeders [Sm4O] auf.
    Notes: Single crystals of Sm4OCl6 and KSm2Cl5 have been obtained by metallothermic reductions of SmCl3 with lithium (in the presence of Sm2O3 or SmOCl) and potassium, respectively, at elevated temperatures in sealed tantalum containers. Sm4OCl6 (hexagonal, P63mc, Z = 2, a = 946.59(4), c = 717.88(4) pm) and KSm2Cl5 (monoclinic, P21/c, Z = 4, a = 888.06(6), b = 784.81(5), c = 1262.77(8) pm, ß = 90.085(6)°) are true divalent samarium compounds, Sm4OCl6 with remarkably short Sm2+-O2- distances (236.0, 237.6 (3x) pm) within the [Sm4O] tetrahedron.
