 Title    Elektroneutrale Pb40 4 -Heterokubaneinheiten in den Aluminatsodalithen Ln4[Al12024](Pb404)2 (Ln = Nd, Sm) Electrically Neutral Pb40 4 Heterocubane Units in Aluminate Sodalites Ln4[A l,2 0 24](Pb4 0 4 )2 (Ln = Nd, Sm)  
 Abstract    Single crystals of Ln4[A lI20 24](Pb40 4)2 (Ln = Nd, Sm) have been prepared by flux techni­ ques. The compounds crystallize with cubic symmetry, space group Oh-Pn3m, a ^ = 9.514(1), asm = 9.481(1) A, Z = 1. The crystal structure is characterized by a [A1120 24] U~ framework. Four of the eight six-membered rings of A104-tetrahedra per sodalite cage are centered by Ln3+ ions. The cages of the resulting electrically neutral network are filled with [Pb40 4]±) heterocubane units. Oxygen of the heterocubane units completes the coordination spheres of the rare earth ions to hexagonal bipyramids.
