“…Therefore, (Ca 2 EuN 0.75 )Sn may be regarded as an example for the rare case of a homogeneously mixed-valent europium situation, e.g., similarly occurring in the cubic Perovskite system Eu 1-x Ce x (Pd 3 B y ). [75][76][77] [24,27,28] Cubic (anti)Perovskite nitrides with group 15 elements have been reported for the systems (Mg 3 N)E with E = As, Sb, [19] (Ca 3 N)E with E = P, As, Sb, Bi, [18] and (Sr 3 N)E with E = Sb, Bi. [21,70] Table 1 gathers selected interatomic distances.…”
