Cobalt(II) oxide (CoO) has been prepared in the zincblende structure by the decomposition of cobalt(II) acetate under vacuum at 290°C. Calorimetric experiments have shown that the zinc‐blende structure is energetically 37 ± 10 kJ/mol less stable than the common rock‐salt form of CoO. This value is in good agreement with the value recently reported by Grimes and Lagerlof of 38 kJ/mol found by a lattice energy calculation
