The alkaline earth metals in liquid ammonia react with carbon monoxide to form the so‐called ‘alkaline earth metal carbonyls’. These products which according to older literature are formulated as M(CO) 2 (M = Ca, Sr, Ba) contain only 65–70% of the expected amount of carbon monoxide. As can be seen from the nitrogen content of the compounds the solvent ammonia participates in the reaction. By hydrolysis leading to a variety of compounds it is demonstrated that the ‘alkaline earth metal carbonyls’ are mixtures of substances such as metal acetylenediolates, metal methoxides, and ammonium carbonate. These mixtures are different from the ‘alkali carbonyls’ as for instance can be seen from the low acetylenediolate content of the ‘alkaline earth metal carbonyls’.
