Die Kristallstruktur von Ytterbiumdisulfid: YbS2 / The Crystal Structure of Ytterbiumdisulfide: YbS2

Abstract

X-ray investigations are described using a single crystal of YbS2 for the first time which formed during a ammono thermal synthesis. It crystallizes in the monoclinic space group C2h 6-C2/c with a = 9,326, b = 4,754, c = 9,025 and β = 118,39°. The atomic parameters and a detailed description of the crystal structure are given. Especially the sulfur-sulfurbridges (dS-S = 2,11 A) represent a characteristic structural element in the a lattice of the genuine disulfide.
