| 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. | | |

| Über Cyanatomercurate M2Hg3(NCO)8 (M = K, Rb, Cs) - Synthesen, Kristallstrukturen und Schwingungsspektren On Cyanatomercurates M2Hg3(NCO)8 (M = K, Rb, Cs) - Syntheses, Crystal Structures and Vibrational Spectra  | | | Abstract
| By mixing aqueous solutions of Hg(CH3COO)2 and MOCN (M = K, Rb, Cs) the tri-clinic compounds M2Hg3(NCO)8 are formed. In a first approximation the crystal structure analysis indicates isolated Hg(NCO)2 molecules besides K+ and NCO~ ions. As in the range of van der Waals radii additional NCO-neighbours are noticed the mercury atoms are surrounded by distorted octahedra. The octahedra around 2/3 of the Hg form infinite chains as in KHg(NCO)3 which are linked together by additional Hg(NCO)2 molecules. Therefore the compound can be formulated as a double salt 2 KHg(NCO)3 • Hg(NCO)2. The vibrational spectrum is discussed. Rb2Hg3(NCO)8 is isotypous while the caesium salt has a double cell volume. | | |

The anion lattice consists of three-dimen-sionally connected Frank-Kasper polyhedra with C. N. 12 and 16. The structure comprises isolated GeTe4-tetrahedra and silver ions, statistically distributed over a number of sites with distorted tetrahedral, trigonal and linear co-ordination. Structural data for some other compounds of the argyrodite family are given. | | |
