 Title    Zur Struktur der Verbindungen BaZn2P2 und BaZn2As2 The Crystal Structure of BaZii2P2 and BaZn2As2  
 Abstract    New yü?2-X^2-compounds, BaZn2?2 and BaZn2As2, were prepared. The structures were determined by X-ray methods. In the case of BaZn2P2 (S.G. I4/mmm; a = 4.019 A, c = 13.228 A) layers of edgeshared ZnP4-tetrahedra alternate with Ba-layers; in the case of BaZn2As2 (S.G. Pnma; a = 10.010 A, b = 4.246 A, c = 10.910 A) Zn and As build a 3D-network of edge and vertex shared tetrahedra with Ba in the holes of this network.

 Title    Ternäre Verbindungen in den Dreistoffsystemen Calcium-Kupfer-Phosphor (Arsen) Ternary Compounds in the Systems Calcium -Copper -Phosphorus (Arsenic)  
 Abstract    By investigations in the systems Ca-Cu-P(As) we found two ternary phases of the formulas CaCuP and CaCuAs, which crystallize in a hexagonal lattice. We suppose a modified Ni2ln-type structure. Some details about a Calcium Copper Phosphide with a ThCr2Si2-type struc-ture are given.

 Title    Darstellung und Struktur der Verbindung CaCu4P2 Preparation and Crystal Structure of CaCu4P2  
 Abstract    of the system Ca-Cu-P resulted in the discovery of CaCu4P2. The compound crystallizes in a trigonal-rhombohedral structure (hexagonal axes: a = 403.6(1) pm, c = 2227.2(2) pm; space group R3m) which contains structural elements of the compound CU3P.

 Title    Darstellung und Kristallstruktur der Verbindungen SEPdP (SE = Seltenerdelement) Preparation and Crystal Structure of SEPdP C om pounds (SE = Rare Earth Element)  
 Abstract    The new compounds SEPdP (SE = L a -G d), which were prepared by heating the elements, crystallize with a modified N i2In-type structure. The phosphides o f SE = D y -L u attain the orthorhombic TiNiSi-type structure. A comparison o f the cell volumes suggests that europium has intermediate valence in EuPdP.

 Title    Strukturvarianten des MgCu2 -Typs: Die Verbindungen Mg2 Ni3P und Mg2 Ni3As  
 Abstract    Variants of the M gC u2 Type: The C om pounds M g2N i3P and M g2N i3As The com pounds M g2N i3P and M g2N i3A s were prepared by heating the elements. Their structures have been determined from single-crystal X-ray data. The structure o f the phosphide is a rhombohedral ternary variant o f the cubic Laves structure type M gCu2 (R 3m ; hexagonal lattice constants: a = 4.971(0)Ä , c = 10.961 (2) Ä). The ordered substitution o f one quarter o f the metal atom s by phosphorus and the resulting shorter distances are responsible for the rhombohedral symmetry. The arsenide crystallizes in the M gC u2 type structure (F d3m ; a = 6.891(1)A , com position M g2N i3A s) with a statistic distribution o f the N i and As atoms; the relevant hom ogeneity range extends from M g2N i2 9A s , , to M g2N i3 5A s0 5.
