It is also shown that theoretically a binary compound should have the sphalerite or wurzite structure instead of the sodium chloride structure if the radius ratio is less than 0.33. The oxide, sulfide, selenide and telluride of beryllium conform to this requirement, and are to be considered as ionic crystals. It is found, however, that such tetrahedral crystals are particularly apt to show deformation, and it is suggested that this is a tendency of the anion to share an electron pair with each cation.

Wohler (182812) thought he had prepared the selenide, telluride, arsenide and phosphide by fusing with the respective elements hut his observations have not been confirmed. Beryllium has probably never been obtained in combination with hydrogen although Winkler, (1891 3) thought he had produced a hydride. Beryllium unites directly with carbon, boron and silicon at the heat of the electric furnace (Ldieau, 1895 2, 1898 7, 1899 ii). It reduces SiCl when heated, (Rauter, 1892 2). 

Johann Heinrich Biltz (Berlin, 26 May 1865-Breslau, 29 October or 2 November 1943), a pupil of Victor Meyer, professor in Breslau (1911), determined the vapour densities of stannous chloride, cuprous and silver chlorides, phosphorus, sulphur, selenium, tin, arsenic, antimony and bismuth, detecting the molecule Sg. His later work was largely on organic chemistry. His brother Eugen Wilhelm Biltz (Berlin, 8 March 1877-Heidelberg, 13 November 1943) was professor in Gottingen (1900), Clausthal (1908), and Hannover. He published an immense number of papers, on colloids, the conductivities of fused salts, the compounds of ammonia with salts, compounds of beryllium and other rarer metals, sulphides, phosphides and tellurides, etc., and the molecular volumes of solid compounds. ...
