Abstract
The crystal structure of germanium selenide has been analysed by X-ray method. The structure is orthorhombic with the space group D 2 h 16 - Pcmn . The dimensions of the unit cell containing four chemical units, GeSe, are a =4.38, b =3.82 and c =10.79 Å. It follows from the positions of all atoms determined by means of the electron-density projection that the structure is of a distorted NaCl type isomorphous with SnS and SnSe, The distances Ge–Se are 2.54, 2.58, 3.30 and 3.39 Å.Keywords
