    Description / Table of Contents: Structures with AIB2- and BaAl4-type Units. I The Compounds Sr4Pd5P5 and Sr2Pd3P3Sr4Pd5P5 (Cmcm, a = 4.177(1) Å, b = 31.377(5) Å, c = 8.581(2) Å, Z = 4) und Sr2 Pd3P3(Pmmm, a = 4.199(1) Å, b = 4.212(1) Å, c = 34.227(4) Å, Z = 4) have been prepared by heating the elements. Both structures contain exclusively units characteristic for the AIB2- and BaAl4-type. The ratio between isolated P-atoms and P2-pairs is interpreted with an ionic splitting of the formulas.
    Notes: Sr4Pd5P5 (Cmcm, a = 4,177(1) Å, b = 31,377(5) Å, c = 8,581(2) Å, Z = 4) und Sr2 Pd3P3(Pmmm, a = 4,199(1) Å, b = 4,212(1) Å, c = 34,227(4) Å, Z = 4) wurden durch Erhitzen der Elemente dargestellt. Beide Strukturen setzen sich ausschließlich aus Baueinheiten zusammen, die für AlB2- und BaAl4-Varianten charakteristisch sind. Das jeweils vorliegende Verhältnis von ,isolierten′ P-Atomen zu P2-Hanteln wird anhand einer ionischen Aufspaltung der Formel interpretiert.

    Description / Table of Contents: Structures with AlB2- and CeMg2Si2-Type Units. The Compounds Eu3Pd4As4, Ca4Pd5P5, and Ca5Pd6P6The new compounds Eu3Pd4As4, Ca4Pd5P5, and Ca5Pd6P6 (space groups and lattice constants see „Inhaltsübersicht“) have been prepared by heating mixtures of the elements. Their structures were determined by means of single-crystal X-ray methods and contain exclusively units, which are characteristic for the AlB2- and CeMg2Si2-type. The non-metal atoms are isolated from each other or connected to pairs; the ratio between these two kinds can be interpreted by ionic splittings of the formulas.
    Notes: Eu3Pd4As4 (Pmmm; a = 4,205(2) Å, b = 4,308(1) Å, c = 12,640(7) Å; Z = 1), Ca4Pd5P5 (Cmcm; a = 4,094(1) Å, b = 31,061(4) Å, c = 8,168(1) Å; Z = 4) und Ca5Pd6P6 (Pmma; a = 8,172(2) Å, b = 4,088(1) Å, c = 19,077(6) Å; Z = 2) wurden durch Erhitzen der jeweiligen Elemente dargestellt. Die mit Röntgen-Einkristallmethoden bestimmten Kristallstrukturen setzen sich ausschließlich aus AlB2- und CeMg2Si2-analogen Einheiten zusammen. Die Nichtmetallatome sind teils voneinander isoliert und teils zu Hanteln miteinander verknüpft; das jeweilige Verhältnis läßt sich mit Hilfe einer ionischen Formelaufspaltung interpretieren.
