## Abstract The synthesis of the previously unknown parent ring system was developed. Treatment of 3‐hydrazino‐1,2,4,5‐tetrazine (4) with diethoxymethyl acetate gave the parent ring system. Similar treatment of 3‐(3,5‐dimethylpyrazol‐1‐yl)‐6‐hydrazino‐1,2,4,5‐tetrazine (2) with one carbon cyclizing
