“…The second compound, ZnP 2' has two modifications: fJ-ZnP 2, monoclinic, with black color (6) and o:-ZnP 2, tetragonal, with light-red color (7). The first was very intensively investigated in (8), where it was found that {3-ZnP 2 represents a so called order-disorder structure.…”

“…Black ZnP2 behaves similarly with a low resistivity parallel to c (10 f2cm) although the anisotropy is less pronounced (Hegyi et al, 1963). In contrast, tetragonal red ZnP2 is a high-resistivity semiconductor, with a resistivity of about 10 s f2cm.…”

“…The semiconductor ZnA% is markedly anisotropic in ~espect to certain physical properties, especially electrical resistivity and optical absorption, and has been investigated extensively in this regard (Fritzsche, 1956;Turner, Fischler & Reese, 1961 ;Hegyi, Loebner, Poor & White, 1963). However, the similarity in X-ray scattering factors of Zn and As (atomic numbers 30 and 33 respectively) has lead to some confusion in characterizing its crystallographic properties.…”

“…The crystal structure of black ZnP2 (Hegyi et al, 1963) is rather unusual in that it contains both P-P and Zn-Zn bonds (Fig. 1).…”

“…The monoclinic cell is analogous to that of black ZnP2 [a=8.85,b=7.29,c=7.56 A, fl= 102 ° 18', space group P21/c (Hegyi, Loebner, Poor & White, 1963)] and, presumably, it is because of the good correlation between these unit-cell characteristics that later workers have assumed monoclinic ZnAs2 to have the black Z nPz crystal structure (Hulliger & Mooser, 1965). The crystal structure of black ZnP2 (Hegyi et al, 1963) is rather unusual in that it contains both P-P and Zn-Zn bonds (Fig.…”

ZnAs2 is monoclinic with a = 9.287 (1), b = 7691 (2), c = 8.010(1) Å, β = 102°28 (1)′, space group P21/c (C52h), Z = 8. The crystal structure was indicated by Patterson synthesis using preliminary intensity data for a pseudo‐orthorhombic unit cell and refined to a weighted residual index of 0 050 using 2031 reflexions collected on a single‐crystal diffractometer with Mo Kα (λ = 0.7107 Å) radiation. The two non‐equivalent Zn sites and four non‐equivalent As sites are each coordinated tetrahedrally, the Zn sites to four As and the As sites to two Zn and two As. The As atoms are arranged in semi‐spiral chains parallel to c. The structure of ZnAs2 differs from that previously assumed for it, the moncclinic black ZnP2 structure, in that it does not contain Zn‐Zn bonds. The marked resistivity anisotropy of ZnAs2 may be a consequence of the arrangement of the Zn(1) and Zn(2) sites in layers parallel to (100).

Professor Wilhelm Klemm rum 8.5. Geburtstag gewidmet Cluster der Hauptgruppenelemente sind keine Raritat; vielrnehr werden imrner neue Spezies diescs Typs gefunden. Die Cluster sind die natiirlichen Stufen zwischen einem Element und seincn isolierten Atomen oder Ionen. Sie bieten als Polykationen und Polyanionen auch Modelle fur die schrittwcise Oxidation und Reduktion eines Elements und bilden die Briicke zwischen den Elementen. Die groBe Mehrheit homonuclear verknupfter Strukturen kommt in den festcn Phasen einfacher Systerne vor. Sie in molekularer Form zu mobilisieren, bedeutet eine groMe Herausforderung. ..Da sagt der kleine Max: Das ist ganz einfach!" [ Wilhelm Klemm.
