    Description / Table of Contents: Zusammenfassung Die Kristallstrukturen von Na4SiO4 und Na4GeO4 sind isotyp, trotz eines Unterschiedes in den Koordinationszahlen: im Na4SiO4 ist nur eines der symmetrisch unabhängigen Natriumatome vierfach koordiniert, während es im Na4GeO4 derer zwei sind.
    Notes: Abstract The crystal structures of Na4SiO4 and Na4GeO4 are isotypic, despite a difference in coordination numbers: in Na4SiO4 only one of the four symmetrically independent sodium atoms is four coordinated, in Na4GeO4 two of them are.

    Description / Table of Contents: Entscheidung zwischen den Raumgruppen Pnam und Pna21 bei der Kristallstruktur des Zr3N4Es wird gezeigt, daß die Kristallstruktur des Zr3N4 in der zentrosymmetrischen Raumgruppe Pnam und nicht in der nichtzentrosymmetrischen Raumgruppe Pna21 kristallisiert.
    Notes: The crystal structure of Zr3N4 is shown to crystallize in the centrosymmetric space group Pnam rather than in the noncentrosymmetric space group Pna21.
