Highly crystalline potassium (heptazine imides) were prepared by the thermal condensation of substituted 1,2,4‐triazoles in eutectic salt melts. These semiconducting salts are already known to be highly active photocatalysts, for example, for the visible‐light‐driven generation of hydrogen from water. Herein, we show that within the solid‐state structure, potassium ions can be exchanged to other metal ions while the crystal habitus is essentially preserved.
