    Description / Table of Contents: NaNb6Cl15 - Darstellung, Struktur, IonenleitungNaNb6Cl15 wird durch Erhitzen von Nb3Cl8, NaCl und Nb unter Ar auf 1 170 〈 T [K] 〈 1 270 in Form schwarzer regulärer Dodekaeder dargestellt. Die Verbindung kristallisiert in der kubischen Raumgruppe Ia3d (a = 2 041,7(2) pm bei Raumtemperatur) und wandelt sich unterhalb 150 K unter Ausbildung tetragonaler Symmetrie um (wahrscheinlich I41/acd, a = 2 037,2(6), c = 2 028,2(2) bei 80 K). Die Na+-Ionen sind bei Raumtemperatur in einer Splitposition dynamisch fehlgeordnet. Die Na+-Ionenbewegung wird IR-spektroskopisch und auf elektrochemischem Weg untersucht.
    Notes: NaNb6Cl15 is prepared by heating Nb3Cl8, NaCl and Nb under Ar at 1 170 〈 T [K] 〈 1 270 forming black regular dodecahedra. It crystallizes in the cubic space group Ia3d (a = 2 041.7(2) pm at room temperature) and transforms to a tetragonal structure below 150 K (probably I41/acd, a = 2 037.2(6), c = 2 028.2(2) pm at 80 K). The Na+ ions are at room temperature dynamically disordered in a split position. Their mobility is investigated by IR spectroscopy and electrochemical methods.
