Abstract

The structure of the yellow «potassium carbonyl», obtained from CO and K in liquid ammonia, has been shown to be potassium acetylenediolate, KOCCOK. From X‐ray powder‐diagrams a tetragonal cell containing two KOCCOK units with a = 3.93, Å, c = 12.75 Å (space group I 4/mmm) has been derived. The KOCCOK units are arranged parallel to the c‐axis with the following internuclear distnaces: K0: 2.67 and 2.78 Å; KK: 3.65 Å; C0 : 1.28 Å; CC: 1.21 Å.
