Decomposition of Molybdenum Hexacarbonyl
THE publication of results by Clougherty 1 and by Kaye 2 of the preparation of face-centred cubic molybdenum monocarbide, and by Goldschmidt 3 of the preparation of face-centred cubic ditungsten carbide, have led us to re-examine the face-centred cubic dimolybdenum carbide reported by Lander and Ger...
